Many studies have been pointing to a high diversity of bacteria associated to legume root nodules. Even though most of these bacteria do not form nodules with legumes themselves, it was shown that they might enter infection threads when co-inoculated with rhizobial strains. The aim of this work was to describe the diversity of bacterial communities associated with cowpea (Vigna unguiculata L. W...

To examine the effect of pathogens on the diversity and structure of plant-associated bacterial communities, we carried out a molecular analysis using citrus and huanglongbing as a host-disease model. 16S rRNA gene clone library analysis of citrus roots revealed shifts in microbial diversity in response to pathogen infection. The clone library of the uninfected root samples has a majority of ph...

The microbiota involved in Korean soy paste (doenjang) fermentation are the key factors determining its quality aspects. In this study, doenjang was prepared by adding three different herbs (Peppermint, mint, and Coriander), their effect on composition evaluated 16S rRNA metagenomic analyses. β-diversity statistics indicated clear distinctions after addition of herbs. A microbial analysis revea...

This study examined microbiological processes during the bio-drying of municipal wastewater sludge (WS) from waste treatment facilities Moscow region (Russia). In just 21 days bio-drying, moisture content mixture WS and wood chips decreased by 19.7%. It was found that members genus Bacillus were main organic matter destructors. period 7 to 14 days, rates mineralization loss highest, bacteria do...

Herein, we report a two-step deglycosylation mediated by the oxidation of glycoside which is different from traditional glycoside hydrolase (GH) mechanism. Previously, we reported a novel flavin adenine dinucleotide (FAD)-dependent glycoside oxidoreductase (FAD-GO) having deglycosylation activity. Various features of the reaction of FAD-GO such as including mechanism and catalytic residue and s...

The composition of bacterial communities growing at the expense of high-molecular weight (HMW; >1000 Da) and low-molecular weight (LMW; <1000 Da) fractions of dissolved organic carbon from a southeastern US estuary was determined by sequencing and terminal restriction fragment length polymorphism (T-RFLP) analysis of 16S rRNA gene amplicons in 2 enrichment studies. 16S rDNA sequence analysis in...
