The Screening of PHB Secretion Strain of PHB Synthesis

摘要

PHB is similar with non degradable plastic which is widely used in most properties. It is supposed to be an excellent substitute of traditional petrochemical plastics because of its biodegradable character. However, the production cost of PHB is much higher than that of traditional plastic. The substitution has not really realized and the production method which can reduce the production cost is to be a research hotspot. In this study, in order to reduce the difficulty of producing process and co-production high added value product, a high yield PHB synthetizing strain was screened for decreasing the production cost among from high concentration ectoine synthetizing halophilic bacteria strains screened from saltern pond and those commercially available halophilic bacteria.
