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