Cell Wall Degrading Enzymes

Cyathus olla, a bird's nest fungus, is being studied as a biological control agent of stubble-borne diseases of canola. Our objectives in this study were to detect and identify plant cell wall degrading enzymes produced by C. olla during solid state fermentation of canola roots. We identified laccase and manganese peroxidase in both 1- and 4-week incubations, and aryl-alcohol oxidase was detected following 4 weeks of incubation. Crude buffer extracts were assayed for cellulases and polygalacturonase, but only the latter was detected. We conclude that C. olla has enzymes to degrade lignin and that it may have use as an inoculant to accelerate stubble decomposition.

This study carried out at Laboratory of Biology, Division of Food and Cultivated Plants Protection, Jayapura from January-June 2008. The objective of this study was to examine the effect of citric acid (CH3COOH) concentration on rate of growth and spore production of Beauveria bassiana (Bals.) Vuill. strain Wamena which grow in short grain rice (beras pera) media. Six different concentration of citric acid (CH3COOH)  were 0; 0,025%; 0, 05%; 0,075%; 0,1% and 0,125% with 5 replicates for each concentration, complete random design were used. Result of this study showed that 0.05% of citric acid significantly affected spore production which mean potential  for biological  control  agent. Key words: Beauveria bassiana (Bals.) Vuill Strain Wamena, rice medium, biological control agent.
