酵母毕氏异常J121防止霉菌腐败和提高保存潮湿的谷物在故障的存储系统。将P. anomala J121作为一种生物防治剂的开发需要对其生理学有深入的了解。P. anomala J121在严格的厌氧条件下生长，温度在3度到37度之间，pH值在2.0到12.4之间，水活度为0.92 （NaCl）和0.85（甘油）。它能吸收广泛的C和n源，并产生杀伤毒素。研究了一种含有淀粉、硝酸盐、乙酸和氯霉素的选择性培养基。异常假丝酵母与白色念珠菌对常见的抗真菌化合物同样敏感。在一系列环境条件下的生长能力有助于生物防治酵母P. anomala J121的竞争能力。(C) 2002年欧洲微生物学会联合会。Elsevier Science B.V.版权所有。
The yeast Pichia anomala J121 prevents mold spoilage and enhances preservation of moist grain in malfunctioning storage systems. Development of P. anomala J121 as a biocontrol agent requires in-depth knowledge about its physiology. P. anomala J121 grew under strictly anaerobic conditions, at temperatures between 3degreesC and 37degreesC, at pH values between 2.0 and 12.4, and at a water activity of 0.92 (NaCl) and 0.85 (glycerol). It could assimilate a wide range of C- and N-sources and produce killer toxin. A selective medium containing starch, nitrate, acetic acid, and chloramphenicol was developed for P. anomala. P. anomala was equally sensitive as Candida albicans to common antifungal compounds. Growth ability at a range of environmental conditions contributes to the competitive ability of the biocontrol yeast P. anomala J121. (C) 2002 Federation of European Microbiological Societies.
