摘要
Decomposition and mineralization of wheat straw inoculated with 8 cellulolytic fungi was investigated in sand culture. Aspergillus fumigatus and Stachybotrys chartarum showed a great potential to degrade wheat straw and weight loss of straw was 35.3 and 27.5% of initial weight after 63 days incubation, respectively. CO2 production was highest after 7 and 14 days for all tested fungi suggesting that the main contribution to CO2 production arose from the water-soluble fraction which was decomposed rapidly. Carbon solubilization from wheat straw occurred, to some extent, in a manner similar to that of straw decomposition. Also, S. chartarum and A. fumigatus solubilized considerable amounts of straw Nitrogen but Gibberella fujikuroi was the best nitrogen dissolving organism.
