专利号:US-2013288320-A1 优先权日:2012-04-27 标题 :Methods and microorganisms for increasing the biological synthesis of difunctional alkanes 发明人:LAU MAN KIT 权利人:BIOAMBER INC 摘要:A method of increasing the production a difunctional alkane in a microorganism that produces a difunctional alkane from alpha-keto acid by increasing the production of homocitrate in the cell relative to a wild-type or parent cell. The production of homocitrate may be obtained by engineering pathways that increase the production of alpha-ketoacid, such as alpha-ketoglutarate.
