Based on screening of cyanobacterial strains and genetic transformation, the efficiency to produce hydrocarbons from CO2 in engineered strains was signicficantly improved, and yields of fat and hydrocarbons were improved 8 times over the wild-type strains (Anabena, Nostoc, Synechocystis, Anacystis and others).
