松口蘑对纤维二糖的利用能力

摘要

Six strains of an ectomycorrhizal fungus, Tricholoma matsutake, were investigated for carbon nutrition and production ofβ-glucosidase in liquid RM media. Cellobiose can serve as a good carbon source comparing with glucose for all six strains. Xylan is also utilized by all tested strains, though the utilization is limited in contrast with glucose or cellobiose. The results provide an indirect proof for the potentiality of T.matsutake in utilizing natural organic materials. Data reported here may contribute to formulate new culture substrates for co-cultivation of T. matsutake and its host plant under controlled conditions.%本文采用液体培养的方法,对六个松口蘑菌种的碳素营养生理及培养液中的β-葡萄糖苷酶的活性进行了分析.结果表明,纤维二糖能很好的支持所有菌株的生长,其效果不逊色于葡萄糖;木聚糖能够-定程度地维持各个菌种的生长,但效果不及葡萄糖和纤维二糖.这些数据为松口蘑具有一定的利用天然有机碳源的潜在能力提供了间接的证据,也为松口蘑人工栽培基质的调制提供了新的思路.
