The diversity and characterization of microorganisms isolated from the soil around several ranches in Korea were confirmed in this study. To isolate halophilic microorganisms, the marine agar medium was basically used and cultivated at 37℃ for several days. After single colony isolation, a total of 116 pure colonies were isolated and phylogenetic analysis was carried out based on the result of 16S rDNA sequencing, indicating that isolated strains were divided into 4 phyla, 23 families, 30 genera and 51 species. To confirm whether isolated strain can be a candidate for the fermentation of diverse food ingredients, amylase, lipase, and protease enzyme assays were performed individually, showing that 92 strains possessed at least one enzyme activity. Especially 4 strains, identified to Jonesia quinghaiensis (isolate name: JSF 19-2), Halomonas alkaliantarctica (isolate name: JSF 21), Bacillus velezensis (isolate name: NWFY-36), and Staphylococcus capitis subsp. urealyticus (isolate name: MSY-5), showed all enzyme activity tested. Moreover, 17 strains showed the ability for auxin production. This result indicated that isolated strains have shown the possibility of the application for the food and feed industries. Therefore, this study has contributed to securing domestic biological resources and the improvement of hydrolytic enzyme activity by using isolated strains.
