The isolation of an alkane-oxidizing strain of Pseudomonas oleovorans which maintains its viability at 5 C is described. This strain epoxidates 1-octene at a rate five times that of the parent strain. The most efficient substrates for induction of the epoxidase are C(7), C(8), and C(9), although C(5) to C(12) also serve as growth substrates and inducers. The greater rate may be attributed to an enhanced general stability of the cells as opposed to a modification of the enzyme system involved.
描述了一种食油假单胞菌的烷烃氧化菌株,该菌株在5℃下仍能保持活力。该菌株使1-辛烯环氧化的速率是亲本菌株的五倍。诱导环氧化酶的最有效底物是C(7)、C(8)和C(9),尽管C(5)至C(12)也可作为生长底物和诱导剂。较高的速率可能归因于细胞总体稳定性的增强,而非所涉及的酶系统的修饰。
