摘要: 微生物体内积累的聚羟基脂肪酸酯(PHAs)是一种可降解的生物塑料,利用微生物合成绿色环保的PHAs替代石化塑料可减少白色污染。嗜盐菌合成PHA可省略繁琐的灭菌和无菌条件培养的苛刻条件,较其他微生物更具有经济效益和竞争性。结合目前国内外嗜盐菌合成PHA的研究进展,对嗜盐菌合成的PHA进行分类,并对由嗜盐菌合成PHA的影响因素进行总结分析。同时,对嗜盐菌合成PHA的发展前景进行了展望。

Abstract: The accumulated polyhydroxyalkanoates(PHAs)in microorganisms are degradable bio-plastics,and replacing the petrochemical plastics by the green and environmental PHAs synthesized in microorganism reduces the pollution of white waste. PHAs biosynthesis from halophilic bacteria eliminates tedious sterilization and the harsh conditions of sterile cultures,thus ensuring more economical benefits and competitiveness than other microorganisms. Based on the research direction and progress of PHAs biosynthesis by halophilic bacteria at home and abroad,this paper classifies the PHAs synthesis by halophilic bacteria,as well as summarizes and analyzes the factors influencing PHAs synthesis by halophilic bacteria;meanwhile,the paper prospects the development of PHAs synthesis by halophilic bacteria.
