Utility
Poly(3-hydroxypropionate-b-lactate) block copolymer using microorganisms
19 Dec 23
The present invention relates to a novel 3-hydroxypropionate-lactate block copolymer [P(3HP-b-LA)], and a method for preparing same, and more specifically, provides a method for preparing a 3-hydroxypropionate-lactate block copolymer, and a 3-hydroxypropionate-lactate block copolymer produced thereby, the method comprising: a first culture step in which, by using recombinant E. coli improved so as to be incapable of biosynthesizing lactic acid, P(3HP) is biosynthesized at the early stage of culturing by having glycerol as a carbon source and through 3-hydroxypropionate-generating genes and an enhanced PHA synthase; and a second culture step in which P(3HP) production is inhibited by using a carbon catabolic repression system for selectively introducing only glucose into E. coli when glycerol and glucose are supplied together as carbon sources, and in which polylactate is biosynthesized to an interrupted P(3HP) terminus by the enabling of the expression of a lactate synthase and a lactyl-CoA converting enzyme through an IPTG induction system.
