A low-cost microBR (microbioreactor) made from PTFE [poly(tetrafluoroethylene)] was used to cultivate a model organism, Pseudomonas aeruginosa DS10-129. The progress of bioprocessing was monitored by comparing the growth of the organism in a microBR, a conventional bench scale bioreactor and a shake flask. Under the microBR conditions, the organism produced 23 mg/ml of pyocyanin that had antimi...

In this study, we have identified a bacterium that can inhibit the growth of Staphylococcus aureus, and further analyzed its antibacterial activity and other biological characteristics and laid the foundation for its future application. Through isolation and culture of the unknown bacteria, the culture characteristics, morphology observation, biochemical test, preliminary antibacterial test, 16...

To determine the prevalence of bacterial mastitis in cattle, milk samples positive for California mastitistest (CMT) were cultured during a period of almost 4 years. The bacterial species isolated from 2904 milksamples studied were coagulase negative Staphylococcus sp. in 879 (30.27%) samples, Streptococcusagalactiae in 642 (22.11%), S. dysgalactiae in 332 (11.43%), E. coli in 295 (10.16%), Sta...
