Opis:
Common citrus fruit peels (banana, grapefruit and orange) as well as low quality lignite were used as precursors for the preparation of cheap activated carbons. In the first step, each of the precursors was air-dried at 110°C, crushed and sieved to the grain size of 5÷6 mm. Next the crushed materials were divided into two parts and subjected to two different treatments: direct activation of the precursors with carbon dioxide or pyrolysis of raw materials followed by physical activation with carbon dioxide. The effect of two variants of thermo-chemical treatment on the elemental composition, textural parameters and acidicbasic character of the surface of adsorbents prepared has been tested. Finally, the activated carbons were tested as adsorbents against two very hazardous and widespread gas pollutants, namely nitrogen dioxide and hydrogen sulphide, as well as toward inorganic and organic liquid pollutants represented by iodine and methylene blue. Depending on the precursor as well as method of preparation, the final products were microporous or mesoporous activated carbons with rather poorly developed surface area ranging from 107 to 527 m2/g and total pore volume from 0.09 to 0.37 cm3/g, showing strongly basic character of the surface. The results obtained have also proved that a proper choice of activation procedure for biomass or low quality lignite allows to produce effective adsorbents with good sorption capacity toward gaseous and liquid pollutants, especially for nitrogen dioxide and iodine.
W pracy przedstawiono wyniki badań nad otrzymywaniem węgli aktywnych ze skór owoców cytrusowych oraz niskiej jakości węgla brunatnego. Adsorbenty węglowe otrzymano na drodze aktywacji bezpośredniej prekursorów oraz aktywacji fizycznej karbonizatów za pomocą tlenku węgla(IV). Zbadano wpływ wariantu aktywacji na skład elementarny, parametry teksturalne i właściwości kwasowo-zasadowe wytworzonych materiałów węglowych, a także na efektywność usuwania tlenku azotu(IV) i siarkowodoru ze strumienia powietrza oraz jodu i błękitu metylenowego z roztworów wodnych. Na podstawie przeprowadzonych badań stwierdzono, że produkty aktywacji charakteryzują się dość przeciętnie rozwiniętą powierzchnią właściwą mieszczącą się w przedziale od 107 do 527 m2/g i całkowitą objętością porów wynoszącą od 0,09 do 0,37 cm3/g. Wykazano również, że zarówno aktywacja bezpośrednia prekursorów, jak i aktywacja fizyczna karbonizatów za pomocą CO2 prowadzi do uzyskania materiałów o wysokiej zawartości popiołu i wyraźnie zasadowym charakterze powierzchni. Przeprowadzone testy sorpcyjne wykazały ponadto, iż węgle otrzymane poprzez aktywację skór owoców cytrusowych oraz niskiej jakości węgla brunatnego charakteryzują się dobrymi zdolnościami sorpcyjnymi wobec zanieczyszczeń gazowych i ciekłych, w szczególności wobec tlenku azotu(IV) i jodu.

Opis:
Effects of 24-epibrassinolide (EBR) treatments on chlorophyll (Chl) degradation and postharvest quality of two lime (‘Persian lime’ and ‘Tahiti’) cultivars during chilling-induced storage were studied in this work. EBR at 0, 2.5, 5 and 10 µM were applied to fruit by vacuum infiltration at 30.63 kPa for 7 min and afterward stored at 4°C for 60 days. Postharvest EBR application effectively maintained greater fruit firmness and lessened weight loss during cold storage. The results displayed that EBR treatments efficiently delayed the reduction of the Chl a contents and hue values. EBR treatments significantly increased ascorbic acid content, total phenolic content (TPC), antioxidant activity, and titratable acidity (TA). On the other hand, the treatments reduced soluble solids concentration (SSC), pH, and SSC/TA ratios during cold storage. Overall, EBR application by vacuum infiltration could be an effective and simple method for maintaining postharvest quality of limes during cold storage.

Opis:
Essential oil extraction technique from mandarin pixie peels by hydro-distillation is optimized by respon-se surface methodology (RSM). Mathematical techniques were used in experimental design to evaluate the impacts of factors that affect the extraction process and improve the yield of the extraction process. A central mixed design based on infl uencing variables such as water ratio (3–5 mL/g), temperature (110–130° C) and extraction time (90–150 min) was adopted with essential oil yield as the target func-tion. Correlation analysis of the mathematical regression model showed that the quadratic polynomial model can be used to optimize hydro-distillation of pixie mandarin oil. The results showed that under the optimum extraction conditions, the highest quantity of essential oils was achieved (7.28 mL/100 g materials). In terms of statistical analysis, the signifi cance levels (p-value <0.05) of the model showed that the experimental results had a good impact between factors. The coeffi cient of determination indicating the match between the experimental value and the predicted value of the model was high (R2>0.9). The chemical composition of the essential oil was analyzed by Gas Chromatography-Mass Spectrometry, revealing the dominance of limonene content (97.667%), which implies that the essential oil of pixie mandarin could be an alternative source of limonene.

Opis:
Currently, agriculture has shifted to green production, in which the recycling of post-production by-products is a key issue. In the present work, by-products such as pomelos were studied to promote consumption and enhance the value of pomelo. From pomelo material, essential oils extracted from pomelo peels, pectin, and drying pomelo products have been diversifi ed. In the extraction process of essential oils, the hydrodistillation method was applied in conjunction with the response surface method to obtain the optimal conditions of infl uence factors. These essential oils were quantifi ed as well as determined for components by GC-MS. The pectin recognition process was done by immersion method in HCl acid (pH 2) and the drying process was made with a heat pump dryer under the effects of drying temperature, drying time and wind rate. The results of the essential oil products reached the highest (0.88 ±0.006 g) at the material size of 3 mm, the distillation time of 27 min, and the ratio of raw materials/solvents of 1/12 g/mL. The main components found in pomelo peeling essential oils included limonene (71.768%), γ-terponene (12,847%), α-Phellandrene (2.979%), β-myrcene (2.668%), 1R-α-pinene (2,656%), and β-pinene (1,191%). The pectin content was the highest under the temperature of 90 oC, extraction time of 60 min and ratio/solvent ratio of 1:32 g/mL. Under these extraction conditions, 48% of concentrated pectin content was obtained. Surveying conditions for drying white pomelo peels are capable of reversing: refunded drying pomelos are drying heat pumps in the following conditions: 50 oC drying temperature, the drying time of 90 min, and wind rate of 12 m/s. Product with hardness 309.862 N.

Opis:
Oxidative stress occurs as a result of an imbalance between production of reactive oxygen species and the regulatory mechanism produced by human cells. The stress contributes to the pathogenesis of inflammatory diseases. Synthetic antioxidants like butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and ascorbic acid, are used in curtailing the menace of the stress. Their potential depends on the type of phytochemicals in the oil. It is on this basis this study aimed at isolating, characterizing and investigating antioxidant potential of rind essential oil of C. reticulata. To achieve this aim, 500g of fresh rinds of C. reticulata were pulverized and hydro-distilled for three hours. GC and GC-MS analysis of the oil revealed the abundance of hydrocarbon monoterpenoids (96%). The most abundant compounds in the oil were D-limonene (82.4%), γ-Terpinene (9.4%) and β-Myrcene (2.2%). The oil exhibited antioxidant activity, with IC50 value (10.73 μl/ml), which was lower to the activity of ascorbic acid (49.14 μl/ml). This shows that the oil is more active than ascorbic acid. Hence, the oil could be explored for the treatment of oxidative stress.

Proteases are one of the most important enzymes that have various physiological and industrial applications. This study was carried out to purify and partially characterize proteases from Citrus sinensis fruit peel. Three active fractions of the proteases (I, II and III) were obtained. The Vmax for proteases I, II, III and pooled fraction were 185.19, 192.31, 111.11 and 163.93 U/ml with Michaelis-Menten’s constant (Km) 1.01, 0.44, 0.67 and 0.37 mg/ml respectively. The enzymes were optimally active at 40-50 °C. However, they retained activity at 60-70 °C. Protease I was stable up to 60 °C while proteases II and III retained more than 80% activity in the range of 25-70 °C. The optimal pH of proteases II and III was 7 while protease I was optimally active at pH 8. The enzymes were stable at alkaline pH especially between 6 and 9 retaining more than 60% of its activity. The stability of these enzymes at high temperature and different pH may be an indication of its potential applications in food, chemical and laundry industries.

Opis:
In this study, cassava starch cross-linked using sodium trimetaphosphate was used as basic material to prepare the preservation coating agent. The addition levels of β-cyclodextrin, phytic acid and glycerol were optimized by response surface methodology with the comprehensive index of oil permeability (OP) and the water vapor permeability (WVP) of starch-based coating. The optimal formulation of the cross-linked cassava starch-based coating was as follows: 3 g/100 g cassava cross-linked starch, 0.7 g/100 g β-cyclodextrin, 0.5 g/100 g phytic acid, and 0.5 g/100 g glycerol. The preservation coating solution prepared by the optimized formula was applied to the postharvest storage of ‘Shatangju’ mandarins. The coating treatment effectively slowed down the decline of firmness during storage for 20 days at room temperature, reduced the decay rate (by 111.73%) and weight loss rate (by 43.40%), and inhibited the postharvest respiration (by 42.06%) of fruit. The soluble solid content, titratable acidity and ascorbic acid content of the coated ‘Shatangju’ mandarins were higher 1.32 times, 1.55 times, and 1.52 times, respectively, compared with the corresponding indexes of the control fruits. All these results indicate that the coating treatment could effectively reduce the loss of nutrients, delay the wilting and decay, prolong the shelf life after harvest, and improve the commercial value of ‘Shatangju’ mandarins.

Opis:
Historia uprawy roślin cytrusowych sięga czasów starożytnych, jednak to w dobie renesansu zyskały one szczególne znaczenie jako element sztuki ogrodowej. Wtedy też zaczęto wykorzystywać nie tylko ich użytkowy charakter, ale również wartości dekoracyjne i znaczenie symboliczne. Pierwsze udokumentowane wykorzystanie cytrusów do celów propagandowych miało miejsce w ogrodzie Medyceuszy w Castello nieopodal Florencji. W okresie tym owoce cytrusów utożsamiano z mitycznymi „złotymi jabłkami” Hesperyd, fakt ten wykorzystany został przez ród Medyceuszy w tworzeniu ogrodu o politycznym przesłaniu. Wspaniałą kolekcję roślin kubłowych, w tym cytrusów, posiadał również w Wersalu król Francji Ludwik XIV. W okresie tym oranżeria i parter pomarańczowy stały się znaczącym eremem ogrodowej kompozycji i programu. Wielkim miłośnikiem uprawy roślin cytrusowych był także elektor saski i król Polski August II Mocny. Podobnie jak Kosma I Medyceusz, utożsamiał się on z mitycznym Heraklesem, a w swych ogrodach w Dreźnie i Warszawie zgromadził olbrzymią kolekcję tych roślin - zwłaszcza pomarańczy gorzkiej. Uprawą cytrusów pasjonował się również ostatni król Polski, Stanisław August Poniatowski, a także car Aleksander II, który odkupił część kolekcji Augusta oraz wybudował nową oranżerię w parku łazienkowskim w Warszawie w celu jej utrzymywania.
The history of growing citrus plants dates back to ancient times but in the Renaissance era they gained particular importance as an element of garden art. At that time they became popular for their decorative and symbolic significance, as well as their originally intended purpose. The first documented use of citrus fruit as “garden art” took place in the garden of the Medici at Castello near Florence. During this period, citrus fruits were identified with the mythical “golden apples” of Hesperides. This fact was used by the Medici family in the garden to create a political message. The great collection of container plants including citrus was also held in Versailles, by French King Louis XIV. From that time the conservatory and orange parterre have become a sig- nifi cant element of garden composition and program. The Elector of Saxony and the King of Poland - August II the Strong was also a great lover of citrus fruits. Similar to Cosimo I de’ Medici, he identified himself with the mythical Heracles, and in his gardens in Dresden and Warsaw amassed huge collections of those plants - especially the bitter oranges which bear “golden” fruits. The last Polish king, Stanislaw August Poniatowski, was fascinated by citrus cultivation, as was Tsar Alexander II, who repurchased part of August II collection and built a new orangery in Lazienki Park in Warsaw for its maintenance.

Nucellar embryony is the major obstacle in getting hybrid seedlings in interspecific crosses in citrus. Hence, the present study was conducted to standardize embryo age, culture media for maximizing germination, and subsequent identification of simple sequence repeat (SSR) markers to differentiate the hybrids. A factorial experiment was conducted with three embryo ages – 80–90, 110–120, and 130–140 days after pollination (DAP). The germination of the rescued immature embryos of acid lime × lemon crosses was initiated on three different growing media. The fruits harvested at 130–140 and 80–90 DAP had a higher number of functional seeds (90%). Older embryos (130–140 DAP) and middle-aged embryos (110–120 DAP) germinated in 100% on Murashige and Skoog (MS) medium supplemented with 500 mg·l -1 malt extract, 1.5 mg·l-1 gibberellic acid (GA3), and 0.02 mg·l-1 naphthalene acetic acid (NAA). MS medium supplemented with 500 mg·l-1 malt extract proved better for the germination of embryos taken at 80–90 DAP. Plantlet survival was the highest in younger embryos (80–90 DAP) cultured on MS basal medium (84.21%) and the lowest in older embryos cultured on MS medium supplemented with 500 mg·l-1 malt extract plus 1.5 mg·l-1 GA3 and 0.02 mg·l-1 NAA. The seedlings obtained from the culture 80–90 DAP had the highest root length (4.9 mm) and shoot length (5.3 mm) at 60 days after inoculation (DAI) on the above medium. SSR marker analysis revealed that CCSM-4 and CAC-33 markers expressed polymorphism between female and male parents, proving their ability to identify the hybrids of ‘Kagzi’ acid lime × ‘Konkan Seedless’ lemon.

Opis:
Evaluating the ecological economic benefits of different ecological restoration patterns in abandoned mines is important in ecological restoration study. Taking the abandoned coal mine in Luoshi Township of Fengcheng county, Jiangxi province, as a case, 4 different ecological restoration patterns (grapefruit with grass vegetation – Pattern I, pine with grass vegetation – Pattern II, grapefruit – Pattern III, and bare slope – Pattern IV) have been conducted to study the runoff and sediment yield under natural rainfall conditions. The results showed that the ecological restoration patterns and rainfall intensity can significantly affect runoff and sediment yield which increased as rainfall intensity increased: Pattern IV > Pattern III > Pattern II > Pattern I. For the optimal ecological restoration with Pattern I, the average runoff and sediment reduction was 59.01 and 77.1%, respectively, in all rainfall intensities. Multivariate analysis of variance (MANOVA) showed that runoff and sediment were significantly affected by ecological restoration pattern and rainfall intensity (P < 0.05). Correlation analysis of runoff and sediment yields indicated that the reduction effect on sediment yield increased with the decrease of runoff, and the relationships between runoff and sediment at different ecological restoration patterns could be fitted with a linear function. Moreover, the vegetation configuration that combines fruit farming with grass can be not only beneficial to control soil and water conservation but produce considerable economic and ecological benefits.

Opis:
This research aimed to study the effect of the position of fruits in a tree (inner or outer) and the number of fruits per panicle (one, two or three) on the growth and quality of citrus ‘Pontianak’. The study was conducted in a citrus orchard in Central Java, Indonesia for two seasons, 2014/2015 and 2015/2016. The results indicated that position of fruits on the tree did not influence weight and diameter of fruits, weight of fruit pulp, and contents of sugars and total acids. Increasing the number of fruits per panicle decreased the weight and diameter of fruits and the weight of pulp but increased the contents of vitamin C and total acids.

Opis:
Citrus bacterial canker, caused by Xanthomonas citri subsp. citri (Xcc), is a destructive disease. So far, the chemicals used to control this pathogen are either ineffective or harmful to the environment. To improve control of this disease, lime (Citrus aurantifolia) were treated with L-arginine, L-methionine, L-ornithine, and distilled water. Plants were inoculated with Xcc, 48 hours post treatment. Lesion diameters of inoculated leaves were evaluated four weeks after inoculation with a bacterial suspension. Changes in β-1,3-glucanase transcript levels and activity of antioxidant enzymes, catalase, peroxidase, and phenylalanine ammonia-lyase were investigated at 48 hours post treatment and 24, 48, and 72 hours post inoculation. Based on the results of phenotypic, antioxidant enzyme activity and a molecular study of the stressed plants, it was found that those plants treated with the amino acid methionine significantly increased the plant induced resistance as well as decreased the severity of disease by reducing necrotic lesion size.
