Biosurfactant Production by Rhodococcus Erythropolis Sp. SB-1A Isolated from North Atlantic Ocean: Study on the Influence of Environmental Conditions
Biosurfactant production by Rhodococcus erythropolis SB-1A was studied based on Atlas oil agar medium in a batch reactor. The strain was isolated from a water sample collected from Northern Atlantic Ocean. Several parameters including carbon source (n-hexadecane, 0.5, 2, 3.5 and 5 v/v%), nitrogen so...
