Bacillus licheniformis powder and preparation method thereof

Abstract

The invention provides bacillus licheniformis powder and a preparation method thereof. The bacillus licheniformis are three types of bacillus licheniformis which are preserved in Agricultural Culture Collection of China and have the preservation numbers of ACCC11080, ACCC10614 and ACCC11106 respectively. One or two or three types of fermentation liquid of bacillus licheniformis are taken to be heated to 50-70 DEG C, heat is preserved for 30 min, and then the fermentation liquid is cooled to 45-55 DEG C, put in a tank, and filtered to obtain clear liquid and thick liquid; clear liquid is concentrated to be mixed with thick liquid, white carbon black and bentonite are put in to be stirred and mixed, and spray drying, cooling and screening are conducted to obtain the bacillus licheniformis powder. By means of the method, fermentation liquid deterioration caused by microorganism infection in the production process can be effectively inhibited; compared with a traditional process, the spore yield is increased by 10.97%; the concentration time is shortened, efficiency is improved by 155%, energy is saved, and cost is reduced; compared with a traditional process, cost is reduced by 50%, and cost is reduced by 60.97% in total.

Description

technical field [0001] The invention relates to a production method of bacillus licheniformis spore powder. Background technique [0002] Bacillus licheniformis (scientific name: Bacillus licheniformis) is a Gram-positive thermophilic bacterium commonly found in soil. It may exist in the form of spores to resist harsh environments; under favorable conditions, it can exist in a growing state. The bacterium can adjust the imbalance of flora to achieve the purpose of treatment, can promote the body to produce antibacterial active substances, kill pathogenic bacteria, can produce antiactive substances, and has a unique mechanism of biological oxygen capture, which can inhibit the growth and reproduction of pathogenic bacteria. It is widely used in the fields of medicine, feed and agriculture. The Bacillus licheniformis described in the present invention is respectively, three kinds of Bacillus licheniformis preserved in China Agricultural Microorganism Culture Collection Cente...

Problems solved by technology

[0006] The disadvantages of this process are low efficiency, high cost, deterioration of fermentation broth in the production process, serious loss of spores, and low yield of spores.

[0007] In addition, there are different dry and solid excipients. Some dry and solid excipients have high cost, and some dry and solid excipients affect product quality, and the amount of dry and solid excipients also affects product quality.
