Screening of Biosurfactant-Producing Bacteria

Abstract:

Firstly, two biosurfactant-producing bacteria named 1# and 2# was selected from 7 strains. Secondly, their growth and metabolism laws that the quantity of metabolic products would reach the highest and the value of surface tension would bottom out in the stationary phase of growth was found in the culture flask. Thirdly, the optimal condition for fermenting was chose by the orthogonal test which was used to study the effect of constituent of fermentation medium, culturing temperature and rotation speed of shaking table on the capability of metabolizing biosurfactants. Finally, compared the interfacial tension of strain 1# with that of strain 2# at the optimum conditions, strains 1# was chose for industrial fermentation.
