Abstract

Corn has the potential to be converted into flour, but its hard endosperm causies it to have a coarse particle size, and consequently, corn flour has high crude fiber, low protein, and high moisture. To overcome these problems, the milling of corn grain can be done by steeping it in water. The steeping process causes spontaneous growth of microbes, such as lactid acid bacteria and cellulolytic bacteria. The use of lactid acid bacteria and cellulolytic bacteria in the steeping process can soften the horny endosperm, which can enable corn grits to be ground into fine flours and which can improve the chemical properties of flour passed through an 80-mesh sieve. This study aimed to obtain isolates of indigenous lactid acid bacteria and cellulolytic bacteria from the corn steeping process, and to apply them as a starter in the steeping process of corn grits to improve the fine flour yield, and the chemical properties of flour passed through an 80-mesh sieve. Isolate E2213BAL was the lactid acid bacteria selected as the highest optical density at the logarithmic phase, while isolate B2121SLT was the cellulolytic bacteria with the highest enzyme activity (4.67 mU/ml). The results showed that the use of bacteria starter and fermentation time can decrease pH, increase total acid in the fermentation liquid, decrease the crude fiber, maintain protein, and decrease the moisture of corn flour passed through an 80-mesh sieve.

Abstract

Isolation of Cellulolytic Bacteria and Characterization of the Enzyme. Four of cellulolitic bacteria isolates had been characterized. The determination of cellulase activity was conducted at the highest production time, using crude enzymes with the modification of Miller methods (1959) on pure cellulose substrates such as CMC (Carboxymethyl cellulose), Avicel and Filter paper Whatman No. 1 as well as agriculture waste such as rice straw, corn cob and banana peel. Cellulase from C4-4, C5-1, C5-3 and C11-1 showed optimum activity at pH 5, 70°C, pH 3.5, 90°C, pH 5, 80°C and pH 8, 70°C, respectively. Avicel is a appropriate substrate for C4-4 cellulase whereas CMC for the other three. C11-1 cellulase has the highest cellulase enzyme activity on rice straw substrate whereas C4-4 cellulase on banana peel substrates. C5-1 and C5-3 cellulase have relatively low cellulase activities in degrading substrates of agriculture waste. However, isolates of C5-1 and C5-3 have high cellulase activities on banana peel substrates.
