Two sulfur-dependent hyperthermophilic archaea, Desulfurococcus strain SY and Pyrococcus strain GB-D, which were isolated from deep-sea hydrothermal vents, utilized free amino acids and peptides obtained from various molecular size fractions of yeast extract. It was found that 11 amino acids were essential for growth. The metabolic products were acetate, i-butyrate, and i-valerate.
两种硫依赖的高温古菌,Desulfurococcus 菌株 SY 和 Pyrococcus 菌株 GB-D,它们从深海热液喷口分离而来,利用酵母提取物中各种分子大小的游离氨基酸和肽类作为生长的营养物质。研究发现,有 11 种氨基酸是必需的。代谢产物为乙酸盐、异丁酸盐和异戊酸盐。
