  • During the biodesulfurization of dibenzothiophene to 2-hydroxybiphenyl by Rhodococcus erythropolis IGTS8, a surfactant-like substance was secreted into the medium resulting in the decrease of the surface tension of the medium. Due to the substance, the optical density (at 600 nm) of the medium had no co-relation with dry cell weight during cultivation. The growth rate of IGTS8 increased by the addition of 1 % Tween 80, but it was inhibited over Tween 80 concentration of 2 % (v/v).
