CULTURE METHOD OF CONTROLLING THE COMPOSITION OF COPOLYMER POLYESTER |
摘要 |
It is intended to develop a technique whereby the composition of a biodegradable copolymer polyester can be arbitrarily controlled while ensuri ng a high productivity at a low cost. Namely, a culture method for producing a copolymer polyester using a microorganism characterized in that the specific feeding speed of a fat to be used as a carbon source to a substrate is controlled at a definite level throughout the culture time or altered in the microbial cell growth phase and in the polyester accumulation phase during t he culture but controlled at a definite level in each phase. A culture method o f controlling the composition of a copolymer polyester product by appropriatel y selecting the type of a fat and/or the specific supplying speed of the fat t o a substrate.
