Opis:
The capacity of five white rot fungi species to degrade linuron, metribuzin and chlorpyrifos when applied both as single pesticides and mixed together in different concentrations on nutritionally poor media was investigated. Our results suggested that Pleurotus ostreatus, Pycnoporus coccineus, Phlebiopsis gigatea and Τrametes versicolor showed a remarkable tolerance to the pesticides, in all media tested. The EC50 values presented a noticeable difference in the mixtures as compared with the individual ones. The minimum growth rate in the mixture was obtained by P. ostreatus whereas P. coccineus appeared to be more efficient than the rest fungal isolates, when cultivated in the soil extract medium. P. coccineus, P. gigantea and T. versicolor produce high levels of polyphenol oxidase, but only T. versicolor was capable of decomposing linuron when combined with metribuzin and chlorpyrifos.

Opis:
White rot disease caused by Sclerotium cepivorum is a major yield reducing fungal disease of garlic found throughout the world, including Iran. The use of chemical fungicides is the most common control method for the disease at the present time. This control measure is costly, contaminates the environment, and harms non-target organisms. Moreover, since the pathogen is soil-borne, chemical control strategy is not quite effective against the disease. In this study, we tried to develop and prepare some new bioformulations based on three antagonistic fungal species: Trichoderma harzianum, T. asperellum, and Talaromyces flavus. Six isolates of the abovementioned fungi were used along with the organic and inorganic carriers, rice bran and talc, to develop twelve new bioformulations. The effectiveness of the bioformulations were then evaluated in the control of garlic white rot disease in the greenhouse conditions in comparison with the healthy control, infected control, and the commonly used fungicide Carbendazim. The design of the experiment was completely randomised. There were 15 treatments each, with four replicates. The results of the greenhouse experiments indicated that almost all the developed bioformulations resulted in significant reductions (34.50 to 64.50%) in the incidence of white rot disease. In general, bioformulations which contained the organic carrier (rice bran) performed more effectively than those that contained the inorganic carrier (talc). Bioformulations which contained an organic carrier (rice bran) were as effective as the fungicide Carbendazim.

Opis:
Związki nitrowe to szeroka grupa ksenobiotyków, które ze względu na swoją silną toksyczność, wyjątkową odporność na rozkład biologiczny oraz skłonność do bioakumulacji, stanowią bardzo poważny problem dla biosfery. Prowadzi się obecnie wiele badań nad mikroorganizmami, które zdołały wykształcić szlaki metaboliczne pozwalające na rozkład takich związków jak 2,4,6-trinitrotoluen, kwas pikrynowy czy kwas 3,5-dinitrosalicylowy. Jednym z takich mikroorganizmów jest podstawczak Phanerochaete chrysosporium, należący do grupy grzybów białej zgnilizny drewna. Artykuł ten poświęcony jest badaniom nad rozkładem kwasu 3,5-dinitrosalicylowego przez P. chrysosporium w warunkach hodowli stacjonarnej w pożywce zawierającej 0,05–0,5% masowego kwasu 3,5-dinitrosalicylowego. Uzyskane wyniki wskazują na zdolność wybranego mikroorganizmu do rozkładu substratu na drodze redukcji grup nitrowych.
Despite intensive efforts put on prevention of environment pollution by nitroaromatic compounds, these xenobiotics have not been eliminated from the biosphere. The physicochemical properties make nitroaromatics extremely recalcitrant to biodegradation. Therefore, microbial degraders of these pollutants are sought after. This paper reports preliminary results of the study on degradation of 3,5-dinitrosalicylic acid (DNS) by a basidiomycetous fungus Phanerochaete chrysosporium under stationary conditions in a culture medium containing 0.05–0.5% v/v of DNS. The results obtained suggest that the fungus degrades DNS through the reductive pathway.

Opis:
Three species of white rot fungi: Cerrena unicolor, Phlebia lindtneri and Pycnoporus sanguineus were cultured in two different media under five different lighting conditions: dark, white, red, blue, and green light. Laccase, cellobiose dehydrogenase, and protease activities were examined in the samples. Blue light efficiently boosted laccase synthesis in C. unicolor and P. sanguineus, whereas the highest activities (20 654 nkat/l) of P. lindtneri laccase were observed when this fungus was maintained in green light. On the contrary, the green light allowed obtaining the highest activities of cellobiose dehydrogenase of C. unicolor and P. lindtneri, while CDH of P. sanguineus seems to be dependent on white light. It is clearly visible that differences in protease activities are noticeable not only between the lights variants but also among the media used. However, high proteases activities are correlated with light variants inducing laccase in Lindeberg and Holm medium. Contrary to the cellulose-based medium, where they are weak in light variants that lead to high CDH activities.

Opis:
The white rot fungi (WRF) isolated from the plantation and natural forests of Arsi forest enterprise (Dagaga and Gambo sites) were screened for their ligninolytic potentials and their Laccases were quantitatively determined. The fungi were grown in both submerged fermentation (SmF) and solid state fermentation (SSF) of wheat bran (WB) and sawdust of Eucalyptus grandis (sawdust). The activities of Laccases of the fungal isolates were quantified and their productions were optimized. Quantification of Laccases indicated that the fungal isolates secreted their highest enzymes on the 8th day of SmF and on 12th day of SSF in WB and sawdust substrates. Laccase activities of SSF were higher than Laccase activities of SmF in both growth substrates. The highest Laccase activities of 0.345 U/ml and 0.379 U/ml were obtained during SmF and SSF of WB, respectively, by isolate 003-2G. Laccase activities of 0.430 U/ml and 0.446 U/ml were also obtained while SSF of sawdust by the same isolate. Laccase quantification data indicated sawdust to be more suitable than WB for Laccase production. 45 °C was most optimum for the Laccase activities and the enzyme was stable in the temperature range of 40-45 °C. It was also found that the Laccases of the fungi were active and stable at pH 5.0. Optimization experiments also revealed that production of Laccases from the fungal isolates can be maximized by adjusting the fungi cultivation conditions and supplementations of the growth media.

Opis:
Within the scope of this study, the hydrolyzed keratin which is an ecological and harmless material, was applied to the wood material surfaces by dipping and spraying method in different concentration rate 1%, 3% and 5%. Within the scope of the research, as wood materials Scots pine (Pinus sylvestris L.) and beech (Fagus orientalis L.) were used. Wood samples were exposed to white and brown rot fungi for 16 weeks and water absorption rate tests for 48-hour period to in order to determine protection performances. According to the results of the water absorption tests, it was observed that the keratin concentrations reduced the water absorption of wood material at least 7 times than control samples. Keratin concentrations were determined to reduce mass loss by at least 50% compared to control samples against rot fungus. As a result; it has been determined that keratin has positive effects on the protection of wood material in tests and that keratin substance can be applied as a natural preservative on wooden surfaces.
