Thallus extract and preparation method thereof

Abstract

The invention relates to the field of comprehensive utilization of tylosin residues and waste water of vitamin B12, and provides a method which is to use the tylosin residues and the waste water of the vitamin B12 as raw materials, separate and extract protoplasm substances in a mycelium to prepare a thallus extract through microbial fermentation treatment, and apply the thallus extract in a biological medium. The thallus extract and the preparation method thereof open a new path for utilization of the tylosin residues and the waste water of the vitamin B12, and provide possibility of realizing clean production which is a goal of sustainable development for the fermentation industry of the tylosin and the vitamin B12. Furthermore, the method solves the problem that the tylosin residues and the waste water of the vitamin B12 pollute environment and are harmful to human health.

Description

Technical field: [0001] The invention relates to the technical field of treatment and comprehensive utilization of antibiotic fermentation industrial waste residue and waste water, in particular to the field of environmental protection treatment and comprehensive utilization of Tylos slag and vitamin B12 waste water. Specifically, it provides a bacterium extract prepared from Tylos slag and vitamin B12 waste water as raw materials after microbial fermentation treatment; the bacterium extract can be used as a nitrogen source in a biological medium and growth Factors, used in bio-fermentation industry. Background technique: [0002] Tylosin is a metabolite of liquid submerged fermentation of Streptomyces and other producing bacteria. During the production process of liquid submerged fermentation, the producing bacteria not only synthesize the desired product tylosin, but also produce a large amount of mycelium and fermentation broth. After treatment and solid-liquid separatio...

AI Technical Summary

Problems solved by technology

In the past, some manufacturers dried it and used it as feed protein. However, because there is a certain amount of tylosin residue in it, referred to as "drug residue", it will form "anti-meat" and "anti-egg" after it is ingested into animals as feed protein. products that pose a direct hazard to humans

Of course, it is also used as agricultural fertilizer after drying, but if the drug residue is not resolved, it will directly destroy the soil micro-ecological balance and induce the emergence of drug-resistant strains

In particular, the fungus residue contains a lot of oil, which often catches fire and burns during drying treatment, causing difficulty in disposal. If it is directly discharged, it will cause serious environmental pollution and waste of resources

So far, there have been no reports of international and domestic research results in this area.
