硫代嗜硫氯菌洗涤悬浮液中二氧化碳固定的主要产物是聚葡萄糖、α-酮戊二酸酯和α-酮-β-甲基戊酸酯。所有这些都可以通过涉及还原羧酸循环的机制形成。在这些条件下,还原戊糖磷酸循环在二氧化碳固定中似乎起着定量的次要作用。
The main products of carbon dioxide-fixation in washed suspensions of Chlorobium thiosulfatophilum are a polyglucose, α-ketoglutarate, and α-keto-β-methylvalerate. All of these can be formed by a mechanism involving the reductive carboxylic acid cycle. The reductive pentose phosphate cycle appears to play a quantitatively minor role in carbon dioxide-fixation under these conditions.
