Abstract
The specific activities and the mRNA expression levels associated with coenzyme A transferase, acetoacetate decarboxylase, and butyraldehyde dehydrogenase were elevated in hyper-solvent-producing Clostridium beijerinckii BA101 during the exponential growth phase. The increase in expression of the sol operon and associated enzyme activities may be responsible for enhanced solvent production by C. beijerinckii BA101.
摘要
在指数生长期，与辅酶A转移酶、乙酰乙酸脱羧酶和丁醛脱氢酶相关的特定活性和mRNA表达水平在高产溶剂的拜氏梭菌BA101中有所升高。sol操纵子表达的增加和相关酶活性可能是拜氏梭菌BA101溶剂产量提高的原因。
