Bacterial autoinduction: looking outside the cell for new metabolic engineering targets.

abstract：BACKGROUND:Triacylglycerols are used in various purposes including food applications, cosmetics, oleochemicals and biofuels. Currently the main sources for triacylglycerol are vegetable oils, and microbial triacylglycerol has been suggested as an alternative for these. Due to the low production rates and yields of micr...
