Preparation method and application of active substance from a kind of termite symbiotic actinomycete

Abstract

The present application relates to the technical field of microbial engineering, and particularly relates to a preparation method and application of an active substance from a termite symbiotic actinomycete. S. tanashiensis The alkaloid compounds can be prepared by using Streptomyces sp. CCTCC M 2019474, and the pyrrolopyridone compound can be prepared by using Streptomyces sp. CCTCC M 2019474. The compounds 1, 3, 6, 9, 10 and 14 can be used as plant pathogenic bacteria inhibitors, and the compound 14 can inhibit the growth of Pseudomonas syringae pv. actinidiae, Burkholderia glumae and Xanthomonas oryzae pv. oryzae, the compound 1 and 6 can inhibit the growth of Pseudomonas syringae pv. actinidiae, the compound 3 can inhibit the growth of Pseudomonas syringae pv. actinidiae, and the compound 9 and 10 can inhibit the growth of Burkholderia glumae; the compound 14 can be used as a herbicide, and the compound 14 can inhibit the growth of Echinochloa crus-galli roots.
