  • Genetically recombinant for degrading kitchen waste
    Patent number: 10584359
    Abstract: Disclosed is a genetically recombinant Saccharomyces cerevisiae useful for degrading and utilizing kitchen wastes. Genes encoding ?-amylase (AMY), glucoamylase (GA) and acid protease (AP) were introduced into the genetically recombinant Saccharomyces cerevisiae using a Saccharomyces cerevisiae multi-gene co-expression vector and successfully expressed and secreted. The Saccharomyces cerevisiae so obtained are capable of secreting amylases and protease to degrade the starch and proteins in kitchen wastes to produce carbon and nitrogen sources such as glucose, polypeptides and amino acids, allowing fermentation into ethanol.
    Type: Grant
    Filed: March 21, 2014
    Date of Patent: March 10, 2020
    Assignee: Guangdong Recyclean Low-Carbon Technology
    Inventors: Zehuan Liu, Long Fang, Kai Yan, Xiaolong Kang, Yangyang Zheng, Renhuai Liu, Jianghai Lin, Wenjuan Xiao, Jingbo Li, Yingxue Gong
