The aims of this work were to isolate microorganisms from vinasse (V) and black liquor (BL), by-products of alcohol and paper industries and to assess their potential as substrates to produce biosurfactants. Thirty-nine microorganisms, 19 from V (acidophilic, a1 to a19) and 20 from BL (alkaliphilic, b1 to b20) were isolated. A high- throughput method was design and set up for surface tension (γ) measurement. In the first screening, 15/39 strains were pre-selected for their capacity of γ reduction of media formulated with V and BL. A Student's t-test was applied to data obtained in the second screening, to search for significant differences among γ values reached in each production media and their respective sterile medium. Three acidophilic (a1, a5, a6) and 3 alkaliphilic (b1, b2, b17) significantly decreased the γ compared to the control (p |
