Abstract

relatively shorter adult phase than the larval stage. The larval stage of this organism lives in piles of organic matter, including in piles of household waste. The ability of larvae to utilize organic matter in their environment is inseparable from the role of potential microbes that produce enzymes associated with their gut. This study aims to isolate, screen, and identify the potential bacteria in producing hydrolytic enzymes from gut of O. rhinoceros larvae. The third instar larvae were dissected aseptically to obtain gut bacterial isolates. The isolates were tested for their ability to produce amylase, cellulose, lipase, and protease using agar plate containing specific substrates. There were eight different isolates, and three of them had the ability to produce all four enzymes. The three isolates were identified as Bacillus. These results can be used as a reference for handling household organic waste.

Abstract

The amylase is an enzyme that widely used in industry. In this research, amylase was isolated from endosymbiont bacteria (EKA 4) of cockroach Pycnoscelus surinamensis from household garbage dump Surabaya. This research aims to identify bacteria EKA 4, produce and characterize amylase from it at various temperature, pH and effect of metal ions. Amylase screening assay was done by imoculating the isolate into medium contain 2% of starch then incubated for 24 hours. Detection of amylase was done qualitatively by measured presence of halozone and quantitatively using DNS method. 16S rRNA analysis found that bacteria EKA 4 has similarity to Bacillus subtilis with 100% of percent identity. Result showed that optimum activity of amylase from B. subtilis were at 40°C, pH 6 and could use ion CaCl2 as a cofactor in a reaction. Thus, utilization of amylase from endosymbiont P. surinamensis could be as an alternative source in big industries.
