  1. Results are from 3 independent preparations of BS. (AB = A. baumannii; EC = E. coli; MRSA = methicillin resistant S. aureus, KP = Klebsiella pneumoniae and SD = Standard deviation). Biosurfactants were tested at 50 mg/ml concentration. Numbers are represented and percent reduction in cell numbers when treated with BS.
