Abstract

Acetate-grown GS-15 whole-cell suspensions were disrupted with detergent and assayed for enzymes associated with acetate catabolism. Carbon monoxide dehydrogenase and formate dehydrogenase were not observed in GS-15. Catabolic levels of acetokinase and phosphotransacetylase were observed. Enzyme activities of the citric acid cycle, i.e., isocitrate dehydrogenase, 2-oxoglutarate sythase, succinate dehydrogenase, fumarase, and malate dehydrogenase, were observed.

摘要

用去污剂裂解以乙酸盐培养的GS - 15全细胞悬浮液,并检测与乙酸盐分解代谢相关的酶。在GS - 15中未观察到一氧化碳脱氢酶和甲酸脱氢酶。观察到了乙酰激酶和磷酸转乙酰酶的分解代谢水平。观察到了柠檬酸循环的酶活性,即异柠檬酸脱氢酶、2-氧代戊二酸合酶、琥珀酸脱氢酶、延胡索酸酶和苹果酸脱氢酶。
