Abstract This project work was carried on the isolation and characterization of pathogenic bacteria from hawked suya meat. Suya meat were bought from the sellers and was collected in raps of aluminum foil. It was then taken to the laboratory for analysis. The sample was homogenized then pipette using 5ml sterile pipette and test tube. The dilution were then cultured on different media, MacConkey agar, Nutrient agar and blood agar ...

ABSTRACT The bacteria Bacillus licheniformis was cultured in nutrient agar and then incubated for 15h at 35oC. The bacteria cells were harvested by centrifugation after incubation. The cell free supernatant was used to estimate alpha-amylase activity. The alpha-amylase obtained was isolated and purified using ammonium sulfate precipitation, gel filtration and ion exchange chromatography. It was purified up to 15.5 fold and a yield of 20.2% on DEAE- Sephadex column with a final specific activity of 12.14 ...
