| Research Abstract |
In this study, influence of bacteria on wood decay was analyzed. To isolate the bacteria involved in wood decay, a decayed wood-pulp perfusion system was developed and applied. An bacterial enrichment surface of pulp in perfusion system contained at least ten bacteria, and then two bacterial strains (E814-1 and E814-2) were isolated as cellulase-producing bacteria. Among them, strain E814-2 was identified as Paenibacillus sp. by 16S rDNA sequencing. This strain closely related to Paenibacillus curdlanolyticus which was reported recently as cellulosome-producing bacteria. In order to analyze the influence of bacteria on wood decay by wood-rotting fungi, co-cultivation of bacteria with fungus on wood was examined. Some bacterial strains improved the weight-loss of wood by fungus. These results suggested that some bacteria help degrade wood by fungus.
