A mutation that affects the expression of spectinomycin resistance in a spectinomycin-resistant (spcA), conditionally asporogenic strain of Bacillus subtilis has been designated srm (spectinomycin resistance modifier). This mutation resulted in altered colony morphology and increased growth rate and sporulation efficiency in the presence of spectinomycin.
在一株对壮观霉素具有抗性（spcA）的枯草芽孢杆菌条件性产孢缺陷菌株中，一个影响壮观霉素抗性表达的突变被命名为srm（壮观霉素抗性修饰因子）。该突变导致在壮观霉素存在的情况下菌落形态改变、生长速率增加以及产孢效率提高。
