Metabolically engineered microorganism strains are disclosed, such as bacterial strains, in which there is an increased utilization of malonyl-CoA for production of a chemical product. Such chemical products include polyketides, 3-hydroxypropionic acid, and various other chemical products described herein. Methods of production also may be applied to further downstream products, such as consumer products. In various embodiments, modifications to a microorganism and/or culture system divert, at least transiently, usage of malonyl-coA from the fatty acid biosynthesis pathway and thereby provides for usage of the malonyl-coA for a chemical product other than a fatty acid. In various embodiments, the fatty acid biosynthesis pathway is modulated to produce specific fatty acids or combinations of fatty acids.
