Environmental regulation of the anaerobic oxidation of methane: a comparison of ANME-I and ANME-II communities.

abstract：:Thermotoga maritima is a marine hyperthermophilic microorganism that degrades a wide range of simple and complex carbohydrates including pectin and produces fermentative hydrogen at high yield. Galacturonate and glucuronate, two abundant hexuronic acids in pectin and xylan, respectively, are catabolized via committed ...
