Results are presented which show that the D-xylose isomerases present in Streptomyces olivaceus and Streptomyces phaeochromogenes NRRL B-3559 are incapable of utilizing D-lyxose as a substrate. The implications of these findings as related to the use of D-lyxose in the selection of constitutive mutants are discussed.
结果表明,橄榄色链霉菌和嗜铬链霉菌NRRL B - 3559中存在的D - 木糖异构酶无法利用D - 来苏糖作为底物。讨论了这些发现与在组成型突变体选择中使用D - 来苏糖的相关性。
