This research was aimed at identifying a bacterium that can produce alkaline proteases. As a result, bacteria that produce proteases were isolated from Batu tannery effluents, tested for protease synthesis on skim milk agar plates, and validated with a protease assay. Microscopic and molecular phylogenetic analyses identified Paenibacillus dendritiformis (BT7) as the bacterial isolate with the highest alkaline protease production. The isolate's maximum enzyme production was obtained by 2% inoculum size, 40°C temperature, 9.0 pH, and a 48-hour incubation time with production media components such as glucose, casein, MgCl2, and 2% NaCl. The maximal enzyme activity was 270 U/mL under …

Total thirty-two strains were isolated from both water and soil samples collected from Naran Valley which is surrounded by the rugged mountains, located in the province of Khyber Pakhtunkhwa, Pakistan. Streak plate method was used to screen the bacterial strains for resistance against selected heavy metals like chromium (Cr), cobalt (Co), copper (Cu), nickel (Ni) and zinc (Zn). Resistance against multiple heavy metals was shown by all the strains, but S15 and W15 were significant as they exhibited a maximum resistance to chromium and copper (1200 µg/ml). These strains also presented multiple antibiotic (ampicillin, tetracycline, chloramphenicol, and erythromycin) resistance patterns. …
