Abstract
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.
