Biopurification systems (BPS) are complex soil-related and artificially-generated environments usually designed for the removal of toxic compounds from contaminated wastewaters. The present study has been conducted to isolate and characterize a collection of cultivable plasmid-carrying bacterial isolates recovered from a BPS established for the decontamination of wastewater generated in a farmyard...
To investigate the mobile gene pool present in wastewater environments, total community DNA was obtained from two distinct raw effluents: urban and slaughterhouse wastewaters. Bacterial community structure was evaluated by DGGE analysis of 16S rRNA gene fragments. Detection of broad-host-range plasmid sequences and integrase encoding genes was carried out through PCR and Southern hybridization. Gene...
The pool of mobile genetic elements (MGE) in microbial communities consists of plasmids, bacteriophages and other elements that are either self-transmissible or use mobile plasmids and phages as vehicles for their dissemination. By facilitating horizontal gene exchange, the horizontal gene pool (HGP) promotes the evolution and adaptation of microbial communities. Efforts to characterise MGE from bacterial...
