Figure 2From: Enhanced biosurfactant production through cloning of three genes and role of esterase in biosurfactant releaseEffect of Proteinase K on purified biosurfactant. The purified biosurfactant was incubated at 37°C with various proteinase K concentrations for 10, 30, 60 and 120 min. The sample was analyzed for biosurfactant activity at 550 nm.Back to article page
