COMPOSITIONS AND METHODS FOR PRODUCING ISOPRENE FREE OF C5 HYDROCARBONS UNDER DECOUPLING CONDITIONS AND/OR SAFE OPERATING RANGES

摘要

The invention features methods for producing isoprene from cultured cells wherein the cells in the stationary phase. The invention also provides compositions that include these cultured cells and/or increased amount of isoprene. The invention also provides for systems that include a non-flammable concentration of isoprene in the gas phase. Additionally, the invention provides isoprene compositions, such as compositions with increased amount of isoprene or increased purity.
