Bioprocessing and Fermentation, Gram positive organisms



Research Interests

There is a critical need for the systematic identification and testing of new gene modulated states that participate in the enhancement of cellular stress resistance. In our laboratory we use the new era of genomic tools that make it possible to identify point mutations, insertions, deletions and/or translocations that have occurred in offspring strains following defined selection processes. In the near future, this comparative approach will provide valuable insights for identifying gene combinations and biochemical pathways that play a role in microbial metabolism and this information may be applied to further improve production using strategic strain modifications. Our primary research interests are the study of Gram positive organisms and we investigate different, but complementary, areas of study with a focus on functional probiosis and bioenergy. Thus far our bioprocessing research has generated technology, peer-reviewed publications, and intellectual property to be directly implemented and translated into the generation of biofuels and functional foods. We have dedicated significant amounts of time towards implementing these new overlapping bioprocessing research areas that target prime university interests.
