Microorganisms and methods for enhancing the availability of reducing equivalents in the presence of methanol, and for producing succinate related thereto
Provided herein is a non-naturally occurring microbial organism (NNOMO) having a methanol metabolic pathway (MMP) that can enhance the availability of reducing equivalents in the presence of methanol. Such reducing equivalents can be used to increase the product yield of organic compounds produced by the microbial organism, such as succinate. Also provided herein are methods for using such an organism to produce succinate.
Method for recyclably using an enzyme
The invention provides methods and systems by which enzymes can be modified to improve solubility, catalytic activity, recoverability, and recyclability. The enzyme may be modified with a thermosensitive copolymer to form an enzyme-polymer conjugate that exhibits upper critical solution temperature (UCST) and/or lower critical solution temperature (LCST)-type behavior in an organic solvent, ionic liquid, or other solvent. Methods and systems of the invention facilitate the use of enzymes as biocatalysts in solvents.
