Pseudomonas Chlororaphis Microorganism, Polyurethane Degrading Enzyme ObtainedTherefrom and Method of Using Enzyme

摘要

Wild-type bacteria with polyurethanase activity, and the ability to excretepolyurethanase into a culture medium have been genetically altered to significantly increase their polyurethanase activity. Biologically pure cultures of these genetically altered are cultured in a inedium containing an inducer for the production of polyurethanase. The bacteria are then removed from the culture medium to provide a preparation with a high polyurethanase activity. One useful genetically altered bacteria is a strain of Pseudomonas chloroaphis . The polyurethanase-containing preparation may then be used directly to degrade
