biosurfactant (BioS) by Bacillus subtilis ZNI5 (MW091416). A Taguchi design permitted the
formulation of a medium composed only of 6% date flour and 0.5% yeast extract within 2
days of incubation at 150 rpm with a maximal surface tension (ST) reduction of about 27.8
mN/m. The characterization of the lipopeptide shows a CMC value of about 400 mg/L with a
minimal ST of 30 mN/m and an ability to disperse oil to about 80 mm at 800 mg/L. Having …
