Abstract： |
The present invention is hygrophilous aeromonad and its application in producing 3-hydroxy butyric acid and 3-hydroxy caproic acid copolymer. The hygrophilous aeromonad of the present invention is hygrophilous aeromonad 45/90 CGMCC No.0650 and its mutant or variant. The production process of the copolymer is the fermentation with the hygrophious aeromonad in culture medium with soybean oil and/or peanut oil. In order ot promote the synthesis of 3-hydroxy butyric acid and 3-hydroxy caproic acid copolymer in the hygrophilous aeromonad, one or several kinds of the nitrogen source, phosphorus source and oxygen supply can be limited, and lauric acid may be added into the culture medium. The present invention makes it possible to produce biodegradable material 3-hydroxy butyric acid and 3-hydroxy caproic acid copolymer in industrial scale. |
