Screening, isolation and mechanism of a nematicidal extract from actinomycetes against the pine wood nematode Bursaphelenchus xylophilus.

ABSTRACT: Actinomycetes are an important microbial resource closely related to human production and life. Approximately 70% of the antibiotics currently used are produced by various actinomycetes. Pine wilt disease (PWD) is caused by the pine wood nematode (PWN) (Bursaphelenchus xylophilus), which is a devastating forest pest that can cause the wilting and death of pine trees. The purpose of this work was to screen out, identify, and ferment active actinomycetes with high lethality to pine wood nematodes and study the active compounds in their secondary metabolites. A group of 227 original strains/isolates of actinomycetes was screened, and Streptomyces sp. TCS19-048 was selected for further analyses. The taxonomic characteristics and molecular analysis results indicated that the strai
