The majority of current biotechnological applications are of microbial origin, and it is widely appreciated that the microbial world contains by far the greatest fraction of biodiversity in the biosphere. Because of their biotech impact, numerous efforts are being undertaken worldwide, with an ultimate goal to deliver new usable substances of microbial origin to the marketplace. However, the di...

Industrial biotechnology involves the utilization of cell factories for the production of fuels and chemicals. Traditionally, the development of highly productive microbial strains has relied on random mutagenesis and screening. The development of predictive mathematical models provides a new paradigm for the rational design of cell factories. Instead of selecting among a set of strains resulti...

Larry’s research focuses on biocatalysis and biodegradation. Laboratory studies are centered on microbial catabolic enzymes; complementary informatics projects revolve around the University of Minnesota Biocatalysis/Biodegradation Database, http://umbbd.ahc.umn.edu/ index.html. Industrial microbiology exploits the ecological adaptations that microorganisms have developed to communicate with and...

process mediated by or involving microorganisms in which a product of economic value is obtained is called fermentation (Casida, Jr., 1968). The terms industrial microbiology and fermentation are virtually synonymous in their scope, objectives and activities. The microbial product may be microbial cells (living or dead), microbial biomass, and components of microbial cells, intracellular or ext...
