Streptomyces sp. AN090126 as a Biocontrol Agent against Bacterial and Fungal Plant Diseases.

ABSTRACT: Bacteria and fungi are major phytopathogens which substantially affect global agricultural productivity. In the present study, Streptomyces sp. AN090126, isolated from agricultural suppressive soil in Korea, showed broad-spectrum antagonistic activity against various phytopathogenic bacteria and fungi. In the 96-well plate assay, the fermentation filtrate of Streptomyces sp. AN090126 exhibited antimicrobial activity, with a minimum inhibitory concentration (MIC) of 0.63-10% for bacteria and 0.63-3.3% for fungi. The MIC of the partially purified fraction was 20.82-250 µg/mL for bacteria and 15.6-83.33 µg/mL for fungi. Gas chromatography-mass spectrometry (GC-MS) analysis revealed that AN090126 produced various volatile organic compounds (VOCs), including dimethyl sulfide and t
