摘要
清华大学和中国科学院微生物研究所合作超额完成了可生物降解塑料专题的攻关任务,该专题包括用废糖蜜为原料生产可生物降解塑料聚羟基丁酸酯(PHB)、基因工程菌生产可生物降解塑料PHB、用水解淀粉为原料生产可生物降解塑料PHB及其共聚物PH-BV、可生物降解塑料PHB的改性和应用研究等4个子专题。并在此基础上实现了世界上首次规模化生产第三代PHA——羟基丁酸共聚羟基己酸酯(PHBHHx),为我国的生物可降解塑料工业化研究开辟了广阔的前景。
Qinghua University and the Institute of Microbiology under the Chinese Academy of Sciences have in cooperation fulfilled the breakthrough tasks of biodegradable plastics, which includes four sub-subjects; production of polyhydroxybutyrate ( PHB) using waste molasses as substrate ; production of PHB by recombinant microorganism; production of PHB and its copolymer PHBV using hydrolyzed starch as substrate; PHB property modification and its application research. Besides, the third generation of PHA, namely PHBHHx has been produced in a certain scale for the first time in the world providing broad prospects for the research on biodegradable plastics commercialization in Cnina.
