Glutathione-S-transferase (GST) activity was determined in 36 species of rhizosphere bacteria with the substrate 1-chloro-2,4-dinitrobenzene (CDNB) and in 18 strains with the herbicide alachlor. Highest levels of CDNB-GST activity (60 to 222 nmol (middot) h(sup-1) (middot) mg(sup-1)) were found in gram-negative bacteria: Enterobacter cloacae, Citrobacter diversus, Klebsiella planticola, Pseudom...

A total of 828 isolates of fluorescent pseudomonads (FPs) were obtained from the leaves (305 isolates) and roots (523 isolates) of potato plants grown in different geographical locations in Japan, and 16S rRNA gene sequences of 776 isolates were successfully determined by direct PCR sequencing. Clustering analysis (≥99% identity) identified 13 and 26 operational taxonomic units (OTUs) for leaf-...

Soil microbial diversity is an important index of agricultural productivity by enhancing soil quality. Present study employed the combination of several methodologies to examine genetic relationships among specific groups of bacteria and to characterize strains at the species level using molecular biotyping techniques. The present study is based upon 16SrDNA analysis for characterisation of bac...

For application of genetically engineered fluorescent Pseudomonas spp., specific markers are required for monitoring of wild-type Pseudomonas strains and their genetically modified derivatives in natural environments. In this study, the specific siderophore receptor PupA of plant growth-promoting Pseudomonas putida WCS358 was used as a marker to monitor wild-type strain WCS358. After introducti...

A pyrimidine-based sensor () has been synthesized through the facile one pot reaction of pyrrole-2-carboxaldehyde, 2-aminobenzimidazole and 1, 3-dimethylbarbituric acid in methanol using a few drops of HCl as a catalyst. Further, compound was fabricated into its fluorescent organic nanoparticles (FONPs) and characterized using DLS and SEM. The photophysical evaluation of the FONPs was done agai...
