姬松茸降解咖啡渣中单宁的研究。

World J Microbiol Biotechnol. 1991 Sep;7(5):573-4. doi: 10.1007/BF00368364.

Pleurotus sajor-caju PL27, a white rot fungus, degraded up to 87% of the tannins in spent coffee grounds as a solid substrate over 32 days. Degradation of tannins was enhanced if potato and dextrose were included. The potential nutritive value of the substrate as animal feed may be improved by this process.

姬松茸 PL27，一种白腐真菌，可在 32 天内将咖啡渣固体基质中的单宁降解高达 87%。如果添加土豆和葡萄糖，单宁的降解效果会增强。通过这个过程，可能会提高作为动物饲料的基质的潜在营养价值。
