Genomic and metabolic manipulations of methylotrophic bacteria. Genomic, physiological and metabolic modeling approaches are used to understand metabolic networks in these bacteria, with the goal of directed manipulation of key metabolic pathways and enzymes for environmentally benign chemical production from methanol.
Physiological heterogeneity of individual cells of M. extorquens AM1 to understand how the behavior of individual cells directs population outcomes during response to stress.
Biomolecular Engineering, Metabolic Engineering
Bacteria as a group possess an almost unlimited and largely untapped catalytic resource for the chemical industry. Not only can bacteria carry out a complex array of stereospecific transformations, these can normally be accomplished in a way that eliminates production of toxic waste products. The ability to apply modern molecular techniques to a broad group of metabolically diverse bacteria, coupled to the current revolution in genomic sequence availability in biology has provided a new opportunity to exploit the metabolic potential of this large group of organisms. This research program is focused on molecular and metabolic manipulations of a specific group of bacteria, the methylotrophs, with the goal of developing environmentally sound and economically viable alternatives to current chemical production.
Methylotrophs are bacteria that grow on methane or methanol. They contain unique metabolic pathways that allow them to grow on these simple substrates, and they contain a series of versatile oxidative enzymes involved in methylotrophic metabolism. Sophisticated genetic techniques have been developed for studying and manipulating these enzymes and metabolic pathways, and genomic sequences are becoming available for key strains. Therefore, this group of bacteria represent an excellent system for developing biologically based chemical production strategies.
