摘要： Production of products by engineered bacteria is increased by regulating cellular respiration. Cellular respiration is controlled by reducing electron transfer enzyme activity. Some examples of electron transfer enzymes include NADH dehydrogenases, Succinate dehydrogenases, ubiquinone synthesis, cytochrome O, and cytochrome D. In one example, deletion of UbiCA prevents respiration. Respiration can the be controlled by addition of ubiquinone or expression of ubiCA.

摘要： In vivo method of producing esters from acetyle coA, such as isoamyl acetate and succinate, has been developed by producing null mutants in pathways that use acetyl coA and by overexpressing products that use NADH and in order to maintain the proper redox balance between NADH and NAD+. The method is exemplified with null mutations in ldhA, adhE, ackA-pta and overexpression of pyruvate carboxylase and alcohol acetyltransferase. This strain produces higher levels of both isoamyl acetate and succinate.
