Production of a biosurfactant Mannosylerythritol lipid by resting cell of Candida sp. SY16 = Candida sp. SY16의 휴식세포를 이용한 생물계면활성제 Mannosylerythritol lipid의 생산

Abstract

The resting cells of Candida sp. SY16 produced a large amount of mannosylerythritol lipid as a biosurfactant when incubated in the distilled water containing only the carbon source. The resting cells exhibited the highest production at 20 g cells per liter on the soybean oil of 75 g/l as a sole substrate and pH 4-5 in the shaking culture. Under the optimal conditions, the biosurfactant was extracellularly produced to 58 g/l after 120 h in jar fermentor, and the yield became higher than that obtained by using the growing cells of the strain in batch fermentation.
