Recovery of Poly(3-hydroxybutyrate) from Recombinant Escherichia coli by Autolysis with Bacteriophage Lambda
박테리오파아지의 세포용해작용을 이용한 재조합 대장균으로부터의 Poly(3-hydroxybutyrate) 회수
Abstract
An autolytic system based on a thermally inducible phage lambda, λHL1, has been applied for the recovery of poly(3-hydroxybutyrate) [PHB] from a recombinant Escherichia coli XL1-Blue, harbouring a plasmid (pSYL105) containing the Alcaligenes eutrophus PHB biosynthesis genes. The lytic capability ofλHL1 was evaluated in flask culture for both lysogens, XL1-Blue (λHL1) and XL1-Blue (λHL1, pSYL105). When the optical density of culture at 600nm(OD600) reached 0.2, cell lysis was induced by increasing the temperature from
