Improved Biosurfactant Production by B14, Stability Studies, and its Antimicrobial Activity.

This work aimed to optimize carbon and nitrogen sources for the growth of B14 and its biosurfactant (BS) production via One-Variable-At-a-Time (OVAT) method. The BS stability under a range of pH and temperatures was assessed. Antimicrobial activity against Gram-positive and Gram-negative pathogens was determined by the agar well diffusion method.
