Desulfurococcus fermentans is the first known cellulolytic archaeon. This hyperthermophilic and strictly anaerobic crenarchaeon produces hydrogen from fermentation of various carbohydrates and peptides without inhibition by accumulating hydrogen. The complete genome sequence reported here suggested that D. fermentans employs membrane-bound hydrogenases and novel glycohydrolases for hydrogen production from cellulose.
产硫化叶菌是已知的第一种能够分解纤维素的古菌。这种高温、严格厌氧的古菌能够从各种碳水化合物和肽类的发酵中产生氢气,并且不会被积累的氢气所抑制。这里报道的完整基因组序列表明,产硫化叶菌利用膜结合的氢化酶和新型糖水解酶从纤维素中生产氢气。
