Analysis of Auxin Productivity and Activity of Extracellular Hydrolases of Bacteria Isolated from a Gut of Larimichthys polyactis

This research focused on the isolation and characterization of the new strains which can be used as microbial resources for auxin production in the agriculture industry. For the isolation of the new microorganism in the gut of Larimichthys polyactis, a marine agar medium was used and 3 colonies were isolated. Through the 16S-based ID service, isolated strains were identified as 1 strain of Niallia circulans and 3 strains of Proteus mirabilis. Verifying the agriculture industrial values of these isolated strains, the productivity of auxin and activity of various enzymes such as amylase, lipase, and protease were confirmed. As a result, isolated 3 strains showed auxin activity and only protease activities which means the possibility of applying them to the production of effective microorganisms in the agriculture industry.
