Title:
BACTERIUM PRODUCING MONOPHOSPHORYL LIPID A AND METHOD OF PRODUCING MONOPHOSPHORYL LIPID A BY USING BACTERIUM
Document Type and Number:
WIPO Patent Application WO/2017/119628
Kind Code:
A1
Abstract:
A bacterium producing monophosphoryl lipid A (MLA) comprising a genetic modification that increases expression of a gene encoding LpxE polypeptide and a method of producing MLA are provided. According to the present invention, MLA may be produced in a simple manner without acid hydrolysis and/or base hydrolysis.
