Evaluation of transcription profile of acetyl-CoA carboxylase (ACCase) and acyl-ACP synthetase (AAS) to reveal their roles in induced lipid accumulation of Synechococcus sp. HS01

While there is a direct association between the expression of acc gene and changes in lipid content of glucose and acetate-grown cultures, no direct relationship exists between the expression of this gene in ostrich oil-grown culture and nitrogen-deficient conditions. Reduced acc gene expression and increased expression of aas gene in conjunction with increased lipid contents in ostrich oil-grown cultures indicated that exogenous fatty acids can be applied directly to the intracellular lipid synthesis and a possible strategy for achieving greater amount of lipids produced by cyanobacteria.
