Abstract
Streptomyces rimosus can produce antibacterial and antifungal antibiotics, which have important applications in medicine and agriculture. Seventy-nine microbial strains were employed to assay interaction between S. rimosus MY02 and different fungi, actinomyces, and bacteria when confront cultured on solid media. The results showed that the presence of a microorganism might affect the activity of another one. When S. rimosus MY02 confront cultured with other microorganisms, the inductive effect might be positive or negative. In this study, fungi showed to be effective elicitors, with a highest inductivity rate of 90.1%, and all of fungi showed positive induction behavior. Followed by bacteria with 59.6% of the tested bacterial strains showing positive inductivity, and the highest inductivity was 54.9%. Only six actinomyces (counting for 40% of the tested actinomyces strains) showed positive inductivity, and the highest induction rate of the strain NK413 was 34.1%. We also found that growth of most of bacteria or actinomyces which showed negative inductivity were similar or better than that of the strain MY02. However, the growth status of the strains was not positive related to inducing ability directly.
