| 发明名称 | Process for polylactic acid production using <i>monascus</i> | ||
| 摘要 | A process for producing polylactic acid (PLA) comprising the steps: fermenting in a fermentation vessel a micro-organism of the genus Monascus in a medium at a pH less than or equal to 5 under conditions which produce lactic acid into the medium, converting the lactic acid produced into lactide, and polymerizing the lactide to form PLA. | ||

| 主权项 | 1. A method for producing polylactic acid (PLA) comprising: (A) fermenting in a fermentation vessel a recombinant micro-organism of the genus Monascus, that has been genetically modified to produce increased levels of lactic acid and have tolerance to lactic acid at a pH of at less than 5, in a medium at a pH less than or equal to 5 under conditions which produce lactic acid into the medium, such that said medium comprises at least 50 g/L lactic acid, (B) converting the lactic acid produced into lactide, and (C) polymerizing the lactide to form PLA. | ||
