Example Embodiment

[0024] The production steps are as follows:

[0025] 1. Selection of bacterial species and subculture: cellulase-producing engineering bacteria, Trichoderma sp., taken from the Institute of Microbiology, Chinese Academy of Sciences, Beijing, number: As3.3030.

[0026] Fermentation activity is more than 1000 units / g straw; after conventional strain slant test tube, shake flask expansion, and fermenter expansion tank until the required amount of liquid seeds;

[0027] Medium formula: potato medium is used for the slant of the strain, and the medium formula ratio is: each liter of culture solution contains 200 grams of potato, 10 grams of glucose, 18 grams of agar, 3 grams of potassium dihydrogen phosphate, and 1.5 grams of magnesium sulfate 7hydrate. , 10 grams of filter paper powder, add water to 1000 ml;

[0028] 2. Cultivation conditions: a, shake flask, use the inoculation loop to scrape the mycelium into the shake flask, and cultivate it on a constant temperature shaking w...

Abstract

The invention is a kind of large-scale producing method for cellulose solid yeast, it uses green trichoderma project strain, it is incubated through fungus cant tube, shaking bottle, the yeasting pot is expanded to the quantity of seeds needed by liquid, then carries on solid yeasting, they are transmitted to the asepsis inoculation room through asepsis channel, then they are placed in the plastic plate to be inoculated with incubation media, incubates for 72 hours, produces primary enzyme, condensates the liquid, and produces it into liquid enzyme through adding in sodium benzoate, the liquid enzyme is filtered and condensed adds in white ammonium sulfate, they are dried and produced into powder industry enzyme. The merit of the invention is that it realizes the solid yeasting large-scale producing, it has not contamination, the quality is high, the price is low.

Description

technical field [0001] The invention relates to a cellulase solid fermentation method. Background technique [0002] Cellulase is an enzyme that hydrolyzes plant fibers. It consists of C-1 enzyme, C-x enzyme and β-glucosidase. It can gradually degrade the cellulose in the plant cell wall until it finally decomposes to generate glucose. Therefore, cellulase is widely used in many processing and manufacturing industries, such as food, beverage, feed, wine making, fermentation, paper making, textile post-treatment, extraction of active ingredients of Chinese herbal medicine, oil exploration, sewage treatment and other fields, all of which are of high quality and high yield after use . In the research work of plant biotechnology, cellulase is often used to hydrolyze the cell wall for genetic engineering and cell engineering operations. So cellulase is known as the golden key to open the treasure house of plants. Cellulase currently only has a few small workshop-style producti...
