A phosphate solubilizing bacterium was isolated from the rhizosphere soil of upland rice and identified by 16S rRNA gene sequencing. The gene sequence showed 99% homology with Alcaligenes faecalis. Based on the gene sequence homology, it was identified as A. faecalis. Interaction effect of this bacterium on growth and yield of soybean was studied under glass house conditions by inoculating the bacterium either alone or in combination with... Read more

Afr. J. Microbiol. Res.

The Gram-positive bacterium Enterococcus faecalis is an etiological agent of endodontic infections in oral biofilms. In the present study, we analyzed the effect of N-acyl homoserine lactones (AHLs) quorum sensing signal molecules on E. faecalis biofilm formation ability. Our results provide important effects of N-Hexanoyl-L-homoserine lactone (C6-HSL) and N-octanoyl-L-homoserine lactone (C8-HSL) molecules on E. faecalis biofilm formation. These... Read more

Effects of climate change on plant associated microbial communities and enzyme activities

African Journal of Microbiology Research

Afr. J. Microbiol. Res.

Environmental alterations leads to fluctuations in the soil microbial population and soil enzyme activities, as different weather parameters affect microbial biota and their activities in rhizospheric soil of crop. An agroclimatic study was carried out to study the effect of environmental alterations on soil microbial population and enzyme activities in rhizospheric soil of rice and wheat crop. Rice and wheat crop were grown under field conditions... Read more
