Molecular Study of Indigenous Bacterial Community Composition on Exposure to Soil Arsenic Concentration Gradient

Actinobacteria and Proteobacteria but a shift towards Proteobacteria was observed with increasing arsenic concentration, and number of Actinobacteria eventually decreases. PCA (Principle Component Analysis) plot of bacterial community composition indicated a distinct resemblance among high arsenic content samples, while low arsenic content samples remained separated from others. Cluster analysis of soil parameters identifies three clusters, each of them was related to the arsenic content. Further, cluster

SPECIES DIVERSITY OF BACTERIA ASSOCIATED WITH FUNGI OF THE GENUS TUBER (TRUFFLES)

Truffles (Tuber spp.) are ascomycete hypogeous fungi, which form ectomycorrhizae with roots of trees, shrubs and herbaceous plants. Their fruiting bodies are valued for their distinctive aroma. The aroma might be partially due to complex bacterial community which colonizes their fruiting bodies. Some bacterial species are also believed to promote the truffle’ fruitification due to the fixation of nitrogen inside the developing truffles. Although truffles, especially of the species Tuber

Bacterial Diversity in Soybean Rhizosphere Soil at Seedling and Mature Stages

period. In summary, the soybean growth period was found to have an important influence on the bacterial community in rhizosphere soil, and bacterial diversity was mainly affected by soil temperature and humidity. Changes in the abundances of Acidobacteria and Proteobacteria showed opposite trends. Our findings provided a theoretical basis for understanding the diversity and changes in the bacterial community in soybean rhizosphere soil.

Metagenomic Profiling of the Bacterial Community Changes from Koji to Mash Stage in the Brewing of Soy Sauce

The improvement of soy sauce fermentation is restricted by the insufficient information on bacterial community. In this study, bacterial communities in the koji and mash stage were compared based on next-generation sequencing technology. A total of 29 genera were identi­fied in the koji stage, while 34 in the mash stage. After koji stage, 7 genera disappeared and 12 new genera appeared in the mash stage. The dominant bacteria were Kurthia, Weissella and Staphylococcus in the koji stage and

Bacterial Community Analysis and Potential Functions of Core Taxa in Different Parts of the Fungus Cantharellus cibarius

related to C. cibarius. For example, Pent et al. (2017) compared and analyzed the diversity and structural composition of some EMF, including C. cibarius, by combining high-throughput sequencing with the assessment of the physical and chemical properties of the mycosphere. These authors suggested that the soil pH and host identity were the predominant factors affecting bacterial community composition. Pent et al. (2020) continued to merge high-throughput sequencing and chemical composition

Recently, the culture-independent molecular biological methods, such as Illumina HiSeq DNA sequencing has been used besides conventional isolation techniques for the analysis of microbial community structures (Watson et al. 2014). So far, there has been no report on the bacterial community in STE using both the Illumina HiSeq DNA sequencing and

The Emergence of Different Functionally Equivalent PAH Degrading Microbial Communities from a Single Soil in Liquid PAH Enrichment Cultures and Soil Microcosms Receiving PAHs with and without Bioaugmentation

Polycyclic aromatic hydrocarbon (PAHs) are common soil contaminants of concern due to their toxicity toward plants, animals and microorganisms. The use of indigenous or added microbes (bioaugmentation) is commonly used for bioremediation of PAHs. In this work, the biodegradation rates and changes in the bacterial community structure were evaluated. The enrichment culture was useful for unambiguously identifying members of the soil bacterial community associated with PAH degradation and yielded

TYPE VB AND VI SECRETION SYSTEMS AS COMPETITION AGENTS OF GRAM-NEGATIVE BACTERIA

Bacterial competition, defined as a local neighbour interaction, can lead to competitors’ coexistence, bacterial community self-organization or rearrangement of species dominance structure in ecological niches. Bacteria developed many mechanisms to communicate and compete. Kin discrimination mechanisms in bacterial populations allow species to distinguish a friend from a foe in bacterial environment. Type Vb and VI secretion systems (TVIbSS and TVISS) play a crucial role in this

showed the presence of members of the Proteobacteria, Spirochaetes, Firmicutes and Bacteroidetes in the analyzed sediments. However, Chloroflexi-related bacteria dominated the detected bacterial community. We also enriched a biphenyl-utilizing mixed culture using the W2 station sediment as an inoculum in chemically defined medium using biphenyl as a sole carbon and energy source. The enriched mixed culture consisted mainly of the Firmicute Paenibacillus spp. Sequences of genes encoding putative
