Degradation of Lignocellulosic Substrates By Bacteria Consortium of Bali Cattle Colon and Organic Waste

A search has been carried out to evaluating potency of bacteria consortium inoculant formulated by selected superior bacteria of bali cattle colon and organic waste as lignosellulosic substrates degrader. Evaluated based on degradation of lignocellulose substrates measurement using diameter of clear/diffusion zone and lignocellulose enzyme activity such as endoglucanase, exoglucanase, xylanase and lignase. This study showed that inoculant of bacteria consortium produce clear zone diameter 0,30 - 0,72 cm, 0,27 - 0,62 cm, 0,43 - 0,78 cm, 0,21 - 0,48, 0,29 - 0,71 and 0,41 - 0,80 cm respectively for carboxy methile cellulase /CMC, avicel micro crystalin, xilan , tannic acid, rice straw, and rice brand substrates, while inoculant BW12C12 produce highest clear zone diameter on all lignocellulose substrates evaluated.meanwhile for enzym activity,bacteria consortium inoculant coded BW12C12 has highest endoglucanase, exoglucanase, xylanase and lignase enzym activity respectively for carboxi methyle cellulose/CMC, avicel micro crystalin, xylan and tannic acid substrates. It was concluded that bacteria consortium inoculant coded BW12C12 was highest potential as lignocellulosic substrates degrader.
