Abstract

The invention discloses high temperature-resistant Pleurotus ostreatus and a screening method and applications thereof. The high temperature-resistant Pleurotus ostreatus has a preservation number ofCGMCC:16378, has good high temperature resistance, and is cultured well and grows well at the temperature of 30-35 DEG C. The fermentation liquor of the high temperature-resistant Pleurotus ostreatuscontains abundant polysaccharides, and the polysaccharides have a strong scavenging capacity on .OH free radicals and O2<->. free radicals. In addition, the high temperature-resistant Pleurotus ostreatus can also be used as edible fungus.

Description

technical field [0001] The invention belongs to the technical field of Pleurotus pluvialis, and specifically relates to a high-temperature-resistant Pleurotus pluvialis and its screening method and application. Background technique [0002] Pleurotus otreatus, belonging to Basidiomycotina, Pleurotus genus Pleurotus, is widely distributed in Hebei, Shandong, Shanxi, Hunan, Hubei, Heilongjiang, Liaoning, Sichuan, Guizhou and other regions in China. It is a kind of edible fungus . The fruit body of Pleurotus pellagra is tender, delicious and nutritious, and is a high-protein, low-fat food. Pleurotus pellagra not only has high nutritional value, but also has certain therapeutic value. The fruiting body of Pleurotus pellagra can reduce blood lipid and cholesterol, and its polysaccharide not only has anti-tumor activity, but also can scavenge free radicals and play an antioxidant role. At present, some areas (such as Hunan, Sichuan, etc.) lack excellent high-temperature Pleurotu...
