Abstract

We improved the culture conditions for a biosurfactant producing yeast, Pseudozyma hubeiensis SY62. We found that yeast extract greatly stimulates MEL production. Furthermore, we demonstrated a highly efficient production of MELs in the improved medium by fed-batch cultivation. The final concentration of MELs reached 129 ± 8.2g/l for one week.

摘要

我们改善了产生物表面活性剂酵母——假丝酵母湖北变种 SY62 的培养条件。我们发现酵母提取物能极大地刺激 MEL 的生产。此外，我们通过补料分批培养证明了在改良培养基中高效生产 MEL。一周后，MEL 的最终浓度达到 129 ± 8.2g/l。
