Embodiment 1

[0030] A microbial strain that can be used for degreasing silk spinning raw materials, the microbial strain is Enterobacter aerogenes, named Enterobacter aerogenes Enterobacter sp.TY-4, the microbial strain was preserved in the Chinese Typical Culture Collection Center, the deposit number is CCTCC NO: M2018291.

Embodiment 2

[0032] This embodiment is further optimized on the basis of the above-mentioned embodiments. The application of a microbial strain in the degreasing of silk spinning raw materials, the described microbial strain is used for degreasing silk spinning raw materials (or cocoons) (or cocoon silk) in the fat.

Embodiment 3

[0034] This embodiment is further optimized on the basis of embodiment 2, further in order to better realize the application of a kind of microbial strain described in the present invention in the degreasing of silk spinning raw materials, the following setting mode is adopted in particular: the described Microbial strains comprise the following steps when being used for silk spinning raw material (or cocoon silk) degreasing:

[0035] (1) Preparation of oil-removing microorganisms;

[0036] (2) microbial deoiling treatment of silk spinning raw materials;

[0037] (3) Water washing: after deoiling, take out the silk spinning raw material and wash it with water;

[0038] (4) drying: the silk spinning raw material after washing is dried;

[0039] (5) Determination of residual oil rate.

Abstract

The invention discloses a microbial strain and its application in degreasing silk spinning raw materials. The microbial strain is Enterobacter aerogenes, named Enterobacter aerogenes Enterobacter sp.TY‑4, the microorganism was preserved in the China Center for Type Culture Collection on June 3, 2018, and the preservation number is CCTCC NO: M2018291; Microbial strains directly act on silk spinning raw materials (or cocoons), which can effectively remove oil from silk spinning raw materials, and can further reduce the use of chemical materials in the deoiling process of silk spinning raw materials, improve the working environment and reduce pollution.

Description

technical field [0001] The invention relates to the technical field of microbial bacteria and its application, in particular to a microbial strain and its application in degreasing silk spinning raw materials. Background technique [0002] Silk spinning raw materials come from all kinds of cocoons, stagnant heads, waste silk, silk reeling residues, etc. that are removed or produced in silk engineering. In addition to sericin and oil, these leftover raw materials also have other pollutants and impurities attached to them. Oil, most of the sericin, wax, etc. must be removed through refining and finishing. [0003] The degreasing of silk spinning raw materials is a major problem in the preparation of silk cotton. Currently, there are two commonly used degreasing methods: chemical and bio-chemical methods. The chemical method mainly uses a large amount of alkalis and other chemical materials to scorch at high temperature to remove grease, the effect is not ideal, and the pollut...
