介绍了甘油生物氧化法绿色生产羟丙酮酸的方法。假单胞菌sp. XP-LM的全细胞具有由甘油生成羟丙酮酸的良好能力。在最佳条件下，200 mM的甘油可生产98.6 mM的羟丙酮酸。甘油是生物柴油燃料生产过程中的一种副产物，现在可以通过生物技术工艺从甘油中生产甘油。因此，本文介绍的生物转化系统不仅提供了一种绿色的羟丙酮酸生产工艺，而且为剩余甘油的利用提供了一条潜在的途径。(C) 2013 Elsevier Ltd.版权所有。
In this work, bio-oxidation of glycerate was introduced for the green production of hydroxypyruvate. Whole cells of Pseudomonas sp. XP-LM were confirmed to have a good ability to produce hydroxypyruvate from glycerate. Under the optimal conditions, Hydroxypyruvate of 98.6 mM was produced from glycerate of 200 mM. Glycerate is now potentially producible from glycerol, a by-product during biodiesel fuel production, through a biotechnological process. Thus, the bioconversion system introduced in this work provided not only a green hydroxypyruvate production process but also a potential pathway of surplus glycerol utilization.
