Abstract

Some sporogenous yeasts (Brettanomyces bruxellensis, Debaryomyces hansenii, Hansenula ciferrii, Hansenula polymorpha, Pichia polymorpha, Saccharomycopsis guttulata, and Saccharomyces chevalieri), isolated from various fruits have been examined for their organic growth factor requisites. H. ciferrii was completely deficient in thiamine, biotin, inositol, riboflavin, niacin, and partially deficient in pantothenic acid. It required an external supply of 0.1-1.0 ppm thiamine, 0.01-0.1 ppm biotin, 10.0 ppm inositol, 0.10 ppm niacin and riboflavin for its optimum growth. H. polymorpha showed partial deficiency only in xanthine. P. polymorpha gave indications of partial deficiencies in thiamine and biotin. S. guttulata was completely deficient in biotin, and partially deficient in adenine sulphate. It required 0.01 ppm biotin for optimum growth. S chevalieri was completely deficient in pyridoxine and partially deficient in thiamine. It required 0.1 ppm pyridoxine for maximum growth. D. hansenii and B bruxellensis were auxoautotrophic for the various growth factors studied.

摘要

已对从各种水果中分离出的一些产孢酵母（布鲁塞尔酒香酵母、汉逊德巴利酵母、西弗瑞汉逊酵母、多形汉逊酵母、多形毕赤酵母、滴状有孢圆酵母和谢瓦利埃酵母）的有机生长因子需求进行了研究。西弗瑞汉逊酵母完全缺乏硫胺素、生物素、肌醇、核黄素、烟酸，泛酸部分缺乏。其最佳生长需要外部供应0.1 - 1.0 ppm硫胺素、0.01 - 0.1 ppm生物素、10.0 ppm肌醇、0.10 ppm烟酸和核黄素。多形汉逊酵母仅在黄嘌呤方面表现出部分缺乏。多形毕赤酵母显示出硫胺素和生物素部分缺乏。滴状有孢圆酵母完全缺乏生物素，硫酸腺嘌呤部分缺乏。其最佳生长需要0.01 ppm生物素。谢瓦利埃酵母完全缺乏吡哆醇，硫胺素部分缺乏。其最大生长需要0.1 ppm吡哆醇。汉逊德巴利酵母和布鲁塞尔酒香酵母在所研究的各种生长因子方面是自养兼异养型的。
