Activity evaluation of promoter stnYp in different Streptomyces hosts. Activities of promoters ermEp*, kasOp*, SP44 and stnYp in S. lividans TK24, S. coelicolor M1154 and S. venezuelae ISP5230 were evaluated with the XylE assay. (A) All cultures were harvested and sampled at the exponential phase (24 h from S. lividans and S. coelicolor and 12 h from S. venezuelae) to detect XylE activity. (B) All cultures were harvested and sampled at the stationary phase (48 h from S. lividans and S. coelicolor and 24 h from S. venezuelae) to detect XylE activity. Statistical analyses were performed and marked (*, p ≤ 0.1; **, p ≤ 0.05; ***, p ≤ 0.01)
