| Abstract: | An actinobacteria D164 was isolated from marine sponge, which has strong bioactivity. According the 16S rRNA genes sequences analysis, physiological and biochemical characterizations, the stain D164 was identified as Streptomyces rochei. The strain D164 fermentation products not only have high resistance to agricultural pathogenic bacteria, but also have high pesticide and herbicide activity, in which the active compounds deserve further study. |
