Abstract

The invention discloses a method for producing fibers and edible fungi by using cotton stalks as raw materials. The method comprises the steps of producing textile fibers by using processes of crushing the cotton stalks, separating skins from cores, degumming cotton stalk skins; washing with water, dehydrating, drying, removing impurities, combing and the like; mixing organic matters generated after the skins and the cores are separated with organic waste water generated after the cotton stalk skins are degummed; and adding auxiliary raw materials to prepare a culture medium for producing edible fungi. The organic matters of the cotton stalks are completely utilized and no pollutant is discharged. The invention discloses a three-level continuous water circulating bio-degumming technology;and the number of pectinase-producing strains is increased, the activity of pectinase is enhanced and the utilization rate of the water is improved through continuous bio-degumming in three levels and recycling of the degumming waste water.

Description

technical field [0001] This patent relates to a method for producing fibers and edible fungi using cotton stalks as raw materials. Background technique [0002] In the existing technology, cotton stalks are used as raw materials to separate the skin from the core, and chemical, enzymatic, and biological methods are used to degumming to produce fibers. These methods cannot fully utilize organic matter other than bast fibers, and at the same time, the sewage generated during production is difficult to treat. Or processing costs are too high. The technology of producing edible fungi using cotton stalks as raw materials produces various edible fungi by crushing cotton stalks as ingredients. These methods do not separate and utilize bast fibers, and the economic benefits are not high. [0003] On September 6, 1995, the Chinese Invention Patent Application Publication No. CN1107917A reported a method for extracting fibers from cotton stalk bark. The method used cotton stalk bark ...
