AI Technical Summary

Problems solved by technology

At present, the large-scale production of bacterial cellulose mainly uses nutrient-rich natural substrates such as coconut water and pineapple juice as the medium for production, and its proportion generally accounts for more than 30% of the total weight of the medium, and the production cycle is generally more than 7 days. The production cost is high and the production raw materials are limited by seasons and regions, which has always been one of the bottlenecks in the development of the bacterial cellulose industry.
There are also reports in the literature that try to reduce or use these natural substrates to produce bacterial cellulose, but the production cycle and product quality are not satisfactory

Embodiment 1

[0018] Mix 1 kg of coconut water and 4 kg of alcohol waste liquid to obtain 5 kg of mixed liquid, add 5 kg of water to the mixed liquid for dilution, and add 200 g of sucrose to supplement the carbon source, thus forming a new alcohol-containing waste liquid Medium. The culture medium was adjusted to a pH value of 3.8, and then sterilized by heat. After cooling, the culture medium was inoculated with Gluconacetobacter xylinum. After 5 days of fermentation on a shallow plate, the thickness of the bacterial cellulose film reached 1.2 cm.

Embodiment 2

[0020] Mix 1 kg of coconut water and 4 kg of alcohol waste liquid to obtain 5 kg of mixed liquid, add 5 kg of water to the mixed liquid for dilution, and add 200 g of sucrose as a carbon source, thus forming a new alcohol-containing waste liquid Medium. The culture medium was adjusted to a pH value of 3.8, and then sterilized by heat. After cooling, Acetobacter xylinum was inserted into the culture medium. After 4 days of shallow plate fermentation, the thickness of the bacterial cellulose film reached 1.2 cm.

Embodiment 3

[0022] Mix 1 kg of coconut water and 4 kg of alcohol waste liquid to obtain 5 kg of mixed liquid, add 5 kg of water to the mixed liquid for dilution, and add 300 g of sucrose as a carbon source, thus forming a new alcohol-containing waste liquid Medium. The medium was adjusted to a pH value of 3.8 and then sterilized by heat. After cooling, Acetobacter xylinum was inserted. After 5 days of shallow plate fermentation, the thickness of the bacterial cellulose film reached 1.5 cm.

Abstract

The invention discloses a production culture medium of a bacteria cellulose including alcoholic waste liquor, which is characterized by mixing the natural substrates and alcohol waste liquor in proportion to obtain mixture, and then mixing uniformly the mixture, water, and sugar to obtain the bacteria cellulose production culture medium. The present invention can effectively reduce the required natural substrates proportionality in the bacteria cellulose production culture medium, reduce production costs and shorten the production cycle; but also finds a new way for the comprehensive utilization of the alcohol waste liquor, wherein, the produced bacteria cellulose products have higher added value and is suitable spread.

Description

technical field [0001] The invention relates to a microbial production medium, in particular to a bacterial cellulose production medium containing alcohol waste liquid. The bacterial cellulose can be produced by using the medium, which can shorten the production period and reduce the production cost. Background technique [0002] Alcohol is an important industrial raw material with a wide range of applications and development prospects. But at the same time, the alcohol industry is a very polluting industry. According to literature reports, using sugarcane molasses or cassava as raw materials, the high-concentration organic wastewater discharged per 1 ton of alcohol production is about 14-15 tons, and the waste liquid COD Cr The value is around 120000mg / L, BOD 5 The value is about 60000mg / L, because its composition is quite complex, it is difficult to treat wastewater. The utilization and management of alcohol waste liquid has been a problem that has been difficult to sol...
