Diversity, antibacterial and phytotoxic activities of actinomycetes associated with Periplaneta fuliginosa.

ABSTRACT:

Background

Insect-associated actinomycetes represent a potentially rich source for discovering bioactive metabolites. However, the diversity, antibacterial and phytotoxic activities of symbiotic actinomycetes associated with Periplaneta fuliginosa have not yet been conducted.

Results

A total of 86 strains of actinomycetes were isolated from the cornicles and intestines of both nymphs and adults of P. fuliginosa. Diversity analysis revealed that the isolated strains were preliminarily identified as 17 species from two genera, and the dominant genus was Streptomyces. A total of 36 crude extracts (60%) obtained from the supernatant of the 60 fermented strains exhibited a potent antibacterial activity against at least one tested pathogenic bacterium. Among t
