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 nonflammable concentration of isoprene in the gas phase. Additionally, the invention provides isoprene compositions, such as compositions with increased amount of isoprene or increased purity.
