摘要： Disclosed are a recombinant microorganism for producing a hydrophobic material, which is subjected to cell-membrane engineering in order to be imparted with at least one characteristic among an increase in a cell-membrane area, an increase in formation and secretion of an outer membrane vesicle, and an increase in formation of an inner membrane vesicle, and a cell-membrane engineering method for preparation thereof, whereby an insoluble hydrophobic material can be produced with high efficiency, the recombinant microorganism for high-efficiency production of carotenoids or violacein analogues is useful for producing natural pigments, antioxidants, antibiotics, cosmetic additives, anticancer agents, food additives, or nutritional supplements, and the natural pigment production technology developed herein achieves a great increase in production ability. Therefore, the present invention is effective at preparing a recombinant strain for efficient production of a variety of industrially and medically useful metabolites and at establishing an efficient preparation method.

摘要： The present invention relates to a recombinant microorganism for malonyl-CoA detection in which a type III polyketide synthase-encoding gene is inserted in the genome or in which a recombinant vector containing the gene is introduced; a method of screening a malonyl-CoA production-inducing substance using the recombinant microorganism; a method of screening a gene which is involved in increased malonyl-CoA production; and a method comprising knocking down the gene, screened by the method, in a microorganism, thus increasing the production of malonyl-CoA in the microorganism, and producing a useful substance in the microorganism using malonyl-CoA as a precursor. The use of the biosensor according to the present invention provides single-step signal generation, utilization in various microorganisms, utilization in self-fluorescent microorganisms, a simple construction method, and a simple screening method. In addition, when the present invention is combined with high-throughput screening, it has advantages in that strains having increased malonyl-CoA producing ability can be screened very easily and rapidly (∼3 days) and can be applied directly to the malonyl-CoA-based production of useful compounds.

摘要： The present invention relates to novel C-glycosyltransferase variants and a use thereof. The C-glycosyltransferase variants according to the present invention have improved glycosidic bond-forming ability as compared with wild-type C-glycosyltransferase, and thus can increase the glycoside production effects of polyketide groups and pseudo-natural products, particularly type I, II, III polyketide, nonribosomal peptides, phenylpropanoids, and other aromatic natural products, and thus can be useful for the preparation of a drug, a food additive, a nutritional supplement, and the like containing a C-glycoside compound as a constituent ingredient.
