Biosurfactant production by native marine bacteria ( Acinetobacter calcoaceticus P1‐1A) using waste carbon sources: Impact of process conditions
Abstract The high cost of biosurfactant production is an obstacle for widespread commercial applications. Cost‐effective generation of biosurfactants could be achieved using industrial wastes and by‐products as substrates and tailoring cultural conditions. In this work, waste streams including refin...
