野生嗜杀白假丝酵母LFA418的产毒条件优化及其毒素粗提物特性
Optimization of Culture Conditions for Toxin Production by Wild Killer Yeast Candida albicans LFA418
摘要
Abstract
The killer property Candida albicans LFA418,a wild strain isolated from a winery in Loulan of Northwest China's Xinjiang region.The killer feature and crude killer toxin characteristics of a wild yeast strain Candida albicans isolated from Loulan winery of Xinjiang were studied.The results indicated that Candida albicans LFA418 had a wide spectrum of killering activity against Pichia kluyveri,Saccharomyces bayanus,Lachancea thermotolerans and Candida lusitaniae.The optimal culture conditions to obtain the maximum yield of killer toxins were as follows:inoculums of C.albicans LFA418,7% (V/V);temperature,25 ℃,and culture time,32 h.The activity of crude killer toxins was stable at pH 4.2-4.6 when temperature was-20 ℃ and 4 ℃ and temperature 4-20 ℃ at pH 4.2.关键词
