Opis:
Filtration through biologically active carbon (BAC) filters is an effective method of organic matter removal during drinking water treatment. In this study, the microbial community in the initial period of filters’ operation, as well as its role in the organic matter removal were investigated. Research was carried out in a pilot scale on two BAC filters (Filter 1 and Filter 2) which were distinguished by the type of inflowing water. It was observed that the number of heterotrophic plate count bacteria and total microbial activity were significantly higher in water samples collected from Filter 2, which received an additional load of organic matter and microorganisms. Despite the differences in the values of chemical and microbiological parameters of inflowing water, the composition of the microbiome in both filters was similar. The predominant taxon was a bacterium related to Spongiibacter sp. (Gammaproteobacteria) (>50% of relative abundance). In both filters, the efficiency of organic matter removal was at the same level, and the composition and relative frequency of predicted functional pathways related to metabolism determined using PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States Software) at level 3 of KEGG (Kyoto Encyclopedia of Genes and Genomes) Orthology – were also similar. The study demonstrated that a 40-day period of filter operation after filling with virgin granular activated carbon, was sufficient to initiate biofilm development. It was proved, that during the initial stage of filter operation, microorganisms capable of biodegradation of various organic compounds, including xenobiotics like nitrotoluene, colonized the filters.
Filtracja przez biologicznie aktywne filtry węglowe (BAF) jest skuteczną metodą usuwania materii organicznej podczas uzdatniania wody przeznaczonej do spożycia przez ludzi. W niniejszej pracy zbadano zbiorowisko drobnoustrojów w początkowym okresie eksploatacji filtrów oraz jego rolę w usuwaniu materii organicznej z wody. Badania przeprowadzono w skali pilotowej na dwóch filtrach BAF (Filtr 1 i Filtr 2) różniących się składem dopływającej wody. Stwierdzono, że liczba bakterii heterotroficznych i całkowita aktywność mikrobiologiczna były znacząco większe w próbkach wody pobranych z Filtra 2 – zasilanego wodą wzbogaconą o dodatkowy ładunek materii organicznej i mikroorganizmów. Pomimo różnic w wartościach parametrów chemicznych i mikrobiologicznych dopływającej wody, skład mikrobiomu w filtrach był podobny. W obu filtrach dominującym taksonem była bakteria spokrewniona z Spongiibacter sp. (Gammaproteobacteria) (>50% względnej liczebności). W obydwóch filtrach efektywność usuwania materii organicznej była na podobnym poziomie oraz skład i względna częstość występowania przewidywanych szlaków funkcjonalnych związanych z metabolizmem, oznaczone przy użyciu PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States Software) na poziomie 3 KEGG (Kyoto Encyclopedia of Genes and Genomes) Orthology były również zbliżone. Badania wykazały, że 40-dniowy okres pracy filtrów po napełnieniu świeżym granulowanym węglem aktywnym był wystarczający do rozwoju biofilmu. Udowodniono, że w początkowym okresie pracy złoża filtracyjne zasiedlane były przez mikroorganizmy zdolne do biodegradacji różnych związków organicznych, w tym ksenobiotyków, np. nitrotoluenu.

Opis:
Characterization of water quality in Lake Qarun indicated that the water is very poor for irrigation and aquatic life. At the same time, the bacterial community was represented mainly by five bacterial phyla with different proportions: Firmicutes (53%), Proteobacteria (33%), Bacteroidetes (7%), Actinobacteria (5%) and Thermi (1%). Furthermore, metagenomes prediction of bacterial communities using PICRUSt indicated important functional gene families associated with metabolism, environmental information, genetic information processing, and cellular processes. It is worth noting that Benzoate degradation had the highest average relative abundance, followed by aminobenzoate degradation among 18 individual KEGG pathways from xenobiotics biodegradation and metabolism which showed higher relative abundance. The obtained data indicate that a different source of pollution in Qarun Lakes has an impact on the bacterial community’s structure, as well as the biota and is expected to cause health problems.

The lime plasters of the excavated monument of Salvankuppam, previously submerged and exposed by the Tsunami occurred in the Indian Ocean on 26th December 2004 was studied with different analytical techniques. The temple is dated 4-5th century CE. The XRF, XRD, FTIR, NMR, SEM-EDX analysis of the lime plasters evidenced particular occurrence of phosphatised bacterial remains in saline conditions. The formation of amorphous Ca-phosphate by bio mineralization was identified in the plasters by the analyses. The plasters are made of air-lime with coarse aggregates and seashells inclusion as confirmed by the thermal and chemical analysis. The microstructure and morphological investigations of mineralized microbial structures by SEM-EDX indicated the formation of amorphous Ca-phosphate. The unordered and fibrous spherulites have hardened and reduced porosity of the plaster by bio mineralization as observed through MIP analysis. The 16S rRNA sequencing has identified the Pseudomonas strains mainly responsible for the clustering of amorphous Ca-phosphate particles around the bacterial colony.

Opis:
The soil microbiome is exposed to technogenic influence during the operation of metal structures. There are quantitative and qualitative changes in the microbiota of the technogenic ecosystem. During the study of the technogenic soil ecosystem (ferrosphere), samples of which were taken in the field (Chernihiv, Ukraine: 51°29’58”N, 31°16’09”E), the presence of corrosively active microbial cenosis was established: sulfate-reducing, denitrifying, iron-reducing (using acetate as the only electron donor, and Fe (III) as the only electron acceptor) and ammonifying bacteria. The predominant representatives of corrosively active groups of bacteria were isolated. They were identified as Bacillus simplex, Streptomyces gardneri, Streptomyces canus (ammonifying bacteria), Fictibacillus sp. (ammonifying bacteria with iron-reducing ability), Anaerotignum (Clostridium) propionicum (organic acid-producing bacteria), Desulfovibrio oryzae (sulfate-reducing bacteria) based on some microbiological, physiological and biochemical, genetic features. Strains of heterotrophic and hemolitotrophic bacteria (individual representatives and their associations) isolated from the technogenic ecosystem can be used in both industrial and technological spheres. The interaction of isolated bacteria in the process of microbial induced corrosion is a prospect for further research.

Opis:
In the last few decades, there has been a growing interest in environmentally friendly sustainable agricultural practices, thus increasing the role of biofertilizers such as rhizobia, which can decrease the need for chemical fertilizers, reduce adverse environmental effects, and help to save money. Therefore, information on the distribution and genetic variation of native rhizobial isolates would aid in selecting novel rhizobial strains that could be developed and used as biofertilizers in legume production. This research was conducted to characterize 24 rhizobial isolates from five legumes on morphological, biochemical, and molecular aspects and determine the phylogenetic relationships among them. Rhizobial isolates were obtained from five Egyptian legumes: faba bean, lentil, pea, clover, and soybean. Morphological characterization classified the isolates into fast and slow growers. Biochemical characterization using API 20E and API 20NE systems showed a large diversity, which may reflect their adaptation in different environments. Moreover, molecular detection of the 16S rRNA gene enabled to characterize 19 of them to the species level. Rhizobial isolates from pea, faba bean, clover, and lentil were identified as Rhizobium leguminosarum and those from soybean were identified as Bradyrhizobium japonicum. These data reflected a narrow diversity of rhizobial species in Egypt. A phylogenetic analysis of the 19 isolates confirmed that B. japonicum isolates were divergent from all other isolates. Furthermore, the phylogram revealed that each group of isolates that originated from the root nodule of a certain legume formed a separate subcluster. The obtained data suggested a narrow range of interspecies variations, which is consistent with the idea of the presence of biovars among the species.

Opis:
Modern molecular techniques have greatly increased our knowledge concerning phylogenetic and functional diversity of microorganisms inhabiting the soil environment. Soil ecosys-tem is relatively complex with a high level of microbiologically diversity. The application of traditional culture-based techniques dose not reflect the total diversity of microbial community in-habiting in soil environment. On the other hand commonly used molecular methods allow for quick and accurate identification and evaluation of the genetic diversity of microorganisms in-habiting this environment. Free-living bacteria belonging to the genus Azotobacter commonly occurring in soil. Azotobacter spp. are the subject of many studies conducted both in Poland and in the world. The interest in these bacteria is largely related to their properties very useful for agriculture. Owing to their capability of fixing atmospheric nitrogen and making it available to plants and production of plant growth promotion and fungicidal substances, they are used in the production of soil bacterial inoculants. In addition, these bacteria are an excellent indicator of soil fertil-ity, which is why they are often used as test microorganisms in many studies. The paper presents an overview of molecular mi-crobiological techniques used to identify and evaluate the genetic diversity of Azotobacter spp. in studies conducted both in Poland and across the world. The ITS PCR, PCR-RFLP methods and 16S rRNA gene amplification are used to identify bacteria of the ge-nus Azotobacter, and PCR MP, RAPD PCR and ARDRA are used to assess the genetic diversity of these microorganisms.

Opis:
Microbial contamination and biodiversity were determined for the drinking water samples collected from selected points of the water supply system in Wroclaw, Poland. All tested samples met the requirements of Polish law, i.e., the Regulation of the Minister of Health. However, the antibiotic resistant bacteria were found. The correlation between the distance of sampling points from water treatment plants and their microbial contamination was not established. Nevertheless, the Na Grobli treatment plant seemed to produce water of higher microbial quality than the Mokry Dwor treatment plant at the moment of sampling. The identification of representative isolates was performed with 16S rRNA gene sequencing and MALDI-TOF mass spectrometry and the results of these two methods were compared, indicating some discrepancies. Nevertheless, bacteria dwelling in drinking water in Wroclaw belonged to the phyla Actinobacteria, Proteobacteria (alpha-, beta-, gamma-Proteobacteria) and Firmicutes . The determination of antibiotic resistance profiles showed that 12 from 17 tested isolates revealed resistance to at least one antibiotic and two strains were multi-drug-resistant.

The aim of this study was to investigate the soil microbial communities of a phosphogypsum waste heap. The soil microbial community structures can differ over time, as they are affected by the changing environmental conditions caused by a long-term exposure to different kinds of pollutions, like is the case of soil in the post-production waste area in Wiślinka (in the northern part of Poland) currently undergoing restoration. Our analyses indicated that the most abundant phyla were Proteobacteria, Acidobacteria, and Actinobacteria, and generally such an abundance is common for most of the studied soils. The most dominant class were Alphaproteobacteria, with their participation in 33.46% of the total reads. Among this class, the most numbered order was Sphingomonadales, whereas among this order the Sphingomonadaceae family was the most abundant one. The Sphingomonadaceae family is currently in the center of interest of many researchers, due to the ability of some of its members to utilize a wide range of naturally occurring organic compounds and many types of environmental contaminants. This kind of knowledge about microbial populations can support efforts in bioremediation and can improve monitoring changes in the contaminated environments.

The aim of the study was to examine the differences in microbial community structure as a result of agricultural practices. Sixteen samples of cultivated and the same number of non-cultivated soils were selected. Gel bands were identified using the GelCompar software to create the presence-absence matrix, where each band represented a bacterial operational taxonomic unit. The data were used for principal-component analysis and additionally, the Shannon-Weaver index of general diversity, Simpson index of dominance and Simpson index of diversity were calculated. Denaturing gradient gel electrophoresis profiles clearly indicated differentiation of tested samples into two clusters: cultivated and non-cultivated soils. Greater numbers of dominant operational taxonomic units (65) in non-cultivated soils were noted compared to cultivated soils (47 operational taxonomic units). This implies that there was a reduction of dominant bacterial operational taxonomic units by nearly 30% in cultivated soils. Simpson dominance index expressing the number of species weighted by their abundance amounted to 1.22 in cultivated soils, whereas a 3-fold higher value (3.38) was observed in non-cultivated soils. Land-use practices seemed to be a important factors affected on biodiversity, because more than soil type determined the clustering into groups.
