Abstract: Disclosed herein are microorganism and methods that can be used for the synthesis of cannabigerolic acid (CBGA) and cannabinoids. The methods disclosed can be used to produce CBGA, ?9-tetrahydrocannabinolic acid (THCA), cannabidiolic acid (CBDA), cannabichromenic acid (CBCA), ?9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabichromene (CBC). Enzymes useful for the synthesis of CBGA and cannabinoids, include but are not limited to acyl activating enzyme (AAE1), polyketide synthase (PKS), olivetolic acid cyclase (OAC), prenyltransferase (PT), THCA synthase (THCAS), CBDA synthase (CBDAS), CBCA synthase (CBCAS), HMG-Co reductase (HMG1), and/or farnesyl pyrophosphate synthetase (ERG20). The microorganisms can also have one or more genes disrupted, such as gene that that controls beta oxidation of long chain fatty acids.
