Research Advances in Biosynthesis of Polyhydroxyalkanoates（PHAs）by Halophilic Bacteria

doi:10.13560/j.cnki.biotech.bull.1985.2018-0843

Abstract

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.

Key words: halophilic bacteria, PHAs, NaCl, carbon source
