Abstract

The invention relates to the technical field of biological degumming, in particular to a preparation method of a high-temperature microbial composite bacterial agent used for pretreatment of ramie biological degumming. The preparation method comprises the following steps: respectively culturing Pediococcus pentosaceae, Bacillus pumilus, Geobacillus and Clostridium thermocellum in the culture medium to obtain the bacterial liquid of Pediococcus pentosaceae, the bacterial liquid of Bacillus pumilus and the bacterial liquid of Geobacillus pumilus Bacterial solution, Clostridium thermocellum bacterial solution, these four kinds of bacterial solutions are mixed to obtain a composite bacterial agent seed solution, and the composite bacterial agent seed solution is inserted into a composite bacterial agent medium for mixed fermentation to obtain a microbial composite bacterium agent. The preparation method provided by the invention is simple and low in cost, and can effectively realize biological degumming of ramie.

Description

technical field [0001] The invention relates to the technical field of biological degumming, in particular to a high-temperature microbial compound inoculant used for ramie biological degumming pretreatment and a preparation method thereof. Background technique [0002] Ramie (scientific name: Boehmeria nivea (L.) Gaudich.) is a subshrub or shrub of the genus Ramie of the Urticaceae family), and its fibers have the characteristics of high strength and high modulus, and are widely used in industrial composite materials. China is the country with the largest ramie production, accounting for about 90% of the world's total production. The raw hemp of ramie contains 20-30% of colloid. In a broad sense, colloid refers to the non-cellulose components in the raw hemp, including hemicellulose, pectin, lignin, water-soluble matter, fat wax, ash, etc. The degumming process in actual production is mainly the process of destroying the hemicellulose and pectin components to separate the ...
