Bacteria have special bio-mechanism to resist toxic heavy metals. This study investigated metal tolerance potentials of bacterial isolates from solid waste dumping sites (Abaji, Bwari, Gosa, Gwagwalada, Kuje, and Kwali) in Abuja, Nigeria. Soil samples were randomly collected each location using soil augers at depths 0 – 15, 15 35 45 cm. They analyzed bacteriologically cultural/biochemical techn...

conclusions regarding the importance of metallo-beta-lactamase (mbl) produced by pseudomonas spp. isolated from hospitals, quick identification of clinical samples should be considered as an important and basic step to treat and control infections caused by pseudomonas spp. results strains with mic > 4 µg/ml were investigated by phenotypic and genotypic methods. in the current study the rate of...

In this study rhamnolipid biosurfactant production was investigated in eighteen strains of Pseudomonas spp.. Rhamnolipid by these strains was determined by a spectrophotometric method in nutrient broth medium (NB). From the 18 strains screened, two Pseudomonas strains (Pseudomonas luteola B17 and Pseudomonas putida B12) which had produced the highest percentage yield of rhamnolipid were examine...

This study was conducted to assess the bacteriological quality of alternative drinking water supply options in southwest coastal areas of Bangladesh. A total of 90 water samples were collected during both dry and wet seasons from household based rainwater harvesting systems (RWHSS), community based rain water harvesting systems (CRWHSs), pond-sand filters (PSFs) and ponds.
