  Pseudomonas chlororaphis NRRL B-30761 produces monorhamnolipids with predominantly 3-hydroxydodecenoyl-3-hydroxydecanoate (C12:1-C10) or 3-hydroxydodecanoyl-3-hydroxydecanoate (C12-C10) as the lipid moiety under static growth conditions. The cloning and sequencing of three genes and proteins involved in the biosynthesis of monorhamnose-lipid (R1L) is described. Expression of two of these genes, i.e., rhlA and rhlB, together in P. chlororaphis NRRL B-30761 increases R1L production by at least 10-fold. Also the generation of a recombinant P. chlororaphis NRRL B-30761 capable of synthesizing dirhamnose-lipid (R2L) is described. Characterization of R1L and R2L produced by the recombinant P. chlororaphis NRRL B-30761 is also described.

  在静态生长条件下，绿假单胞菌（Pseudomonas chlororaphis）NRRL B-30761 产生的单鼠李糖脂主要以 3-hydroxydodecenoyl-3-hydroxydecanoate (C12:1-C10) 或 3-hydroxydodecanoyl-3-hydroxydecanoate (C12-C10) 为脂质分子。本文介绍了参与单鼠李糖脂（R1L）生物合成的三个基因和蛋白质的克隆和测序。在 P. chlororaphis NRRL B-30761 中同时表达其中的两个基因，即 rhlA 和 rhlB，可使 R1L 的产量增加至少 10 倍。此外，还描述了能够合成地尔汉糖脂质（R2L）的重组 P. chlororaphis NRRL B-30761 的产生过程。还描述了重组 P. chlororaphis NRRL B-30761 产生的 R1L 和 R2L 的特征。
