Functional microorganisms decompose various organic matter by enzyme activity and suppress plant disease caused by pathogen. This study was conducted to isolate and select functional microorganisms with protein or carbohydrate degradation activities and antagonistic activity against turfgrass fungal pathogens for eco-friendly turfgrass management in golf course from compost containing livestock manure of poultry or swine. Totally 68 isolates collected from livestock manure compost strains were isolated and tested for their activities of amylase, protease and lipase and antagonistic activities against Rhizoctonia solani AG2-2, R. solani AG1-1, and Sclerotinia homoeocarpa. Among the isolates, 34 strains were selected as functional microbes showing higher activities of amylase and protease. Three isolates of ASC-14, ASC-18, and ASC-35 among the 34 strains were selected as antifungal bacterial strains repressing the above 3 turfgrass fungal pathogens. Analysis results of 16s rRNA gene sequence and phylogenic cluster indicated that ASC-14 and ASC-18 belonged to Bacillus amyloliquefaciens, while ASC-35 was B. subtilis, respectively.
