Problems solved by technology

[0006] Hot pressing first, and then hydrolyzing with keratin-degrading bacteria, this is another method of recycling keratin waste, but it is controversial at home and abroad, and no industrialized technology and products have been seen so far

Embodiment 2

[0062] Embodiment 2, the processing time of step 3) is changed into 96 hours, and all the other are with embodiment 1.

Embodiment 3

[0063] Embodiment 3, the processing time of step 3) is changed into 144 hours, all the other are with embodiment 1.

[0064] In the above-mentioned Example 1, Example 2 and Example 3, the results of the liquid transformation of Bacillus ZJUEL31410 cells to feathers are specifically shown in Table 5.

[0065] processing time

[0066] Because the selected bacillus ZJUEL31410 of the present invention is a kind of bacillus that requires facultative oxygen, so the biodegradation treatment of feathers can also be realized by using the liquid cell static transformation method; only the required treatment time is longer than that under aerobic conditions , the degradation rate is slower.

Abstract

A process for degradating feather by use of microbes includes such steps as preparing the substrate of feather to be transformed, obtaining the Bacillus licheniformis ZJUEL31410 (CGMCC 1397), and microbial transforming of the feather to obtain forage.

Description

technical field [0001] The invention relates to a method for microbial degradation of feathers. Background technique [0002] Worldwide, poultry farming produces up to 4 million tons of feathers each year, most of which are considered waste or underutilized. Keratin can be degraded by microorganisms, and a variety of keratin-degrading bacteria have been isolated and deeply studied. Treated with microbial keratinase, feathers can be converted into feed with nutritional value. If keratinase is successfully developed, animal feathers and hair will be a new source of protein. In addition, keratinase has many other application values. Today, with the emphasis on sustainable development, the research and development of keratinase and the utilization of keratin waste can be regarded as a promising environmental protection measure. Keratinase purified from microorganisms has strong activity and can hydrolyze a variety of refractory fibrous proteins, such as collagen, elastin and...
