Introduction: Chinese scientist Shi Jiaxing, Professor of biology at North Carolina State University Raleigh, has found an enzyme that can decompose chicken hair, which may be used to "digest" toxic proteins that cause mad cow disease and human Creutzfeldt Jakob disease According to Shi Jiaxing, it has been found in the research that a kind of keratinase secreted by Bacillus subtilis can decompose chicken hair and make it become a feed that can be digested and absorbed by chickens and is helpful for growth Because the keratin in chicken hair is the same beta structure as the virus protein that causes mad cow disease, Professor Shi thought that keratin might be able to deal with mad cow disease Experiments conducted jointly by professional testing institutions show that keratinase can indeed destroy toxic proteins and make them lose the ability of infection Professor Shi said that they plan to use the patented technology to develop two kinds of products, one is used to dissolve the possible toxic protein in animal meat and bone meal feed, and the other is used as a disinfectant to prevent medical devices from being infected by the toxic protein after surgery.
