Effect of LED on Wheat Bran Digestion by Pleurotus geesteranus Mycelia
摘要
Abstract
Effect of LED light (L)on the digestion of Se-enriched wheat bran (SeWB)by the mycelia of P leurotus geesteranus through the fungal metabolism was investigated to evaluate its potential for nutrient transformation applications.The results showed that,under intermittent LED exposure,the ergosterol content in the powder of the mushrooms cultured on the SeWB medium (Se-L treatment)and on the non-enriched wheat bran medium (CK-L treatment)increased 14.2% and 8.8%,respectively,over the shaded groups (Se and CK treatments);and,the Se transformation efficiency of Se-L treatment increased by 34.3%,while the soluble protein in Se-L mushroom powder raised 42.6% over those of the shaded counterparts.The total sugar content in the mushroom powder from Se-L or CK-L decreased,but the contents of naringin and nobiletin increased as compared to Se or CK samples. Consequently,the intermittent LED appeared to stimulate the fungal mycelia growth and metabolism leading to a heigThened Se and nutrient transformations from the SeWB medium resulting in an improved nutritional quality of the product made of the cultured mushrooms and SeWB.关键词
