Annotation Of Hypothetical Genes In Lactococcus Lactis Ssp. Il403, Jennifer A. Tangires Apr 2024

Annotation Of Hypothetical Genes In Lactococcus Lactis Ssp. Il403, Jennifer A. Tangires

Student Scholar Showcase

The human gastrointestinal tract (GIT) harnesses various microbial organisms involved in almost all processes of physiological homeostasis, among these are lactic acid bacteria (LAB). These bacteria, almost all of which belong to the order Lactobacillales, are able to produce lactic acid, and play an important role in food preservation because they produce bacteriocins. Bacteriocins are antimicrobial proteins that are used to fight off related bacteria in their environment that are competing for the same resources. This study focuses on a specific LAB strain, Lactococcus lactis ssp. IL1403 where 21.9% of its predicted genes have not yet been assigned a function. …


Comparative Genomics Of Selected Lactobacillus Helveticus Strains, Cain Petty Apr 2024

Comparative Genomics Of Selected Lactobacillus Helveticus Strains, Cain Petty

Undergraduate Research Conference

My research is to compare two strains (D76 and H10) of Lactobacillus helveticus and a shared gene between them. I would want to experiment with overexpression to test for any difference in the regulatory function of genes associated with CggR - the central glycolytic genes regulator. The poster I am presenting would outline this and provide a clearer understanding of genes and potential overexpression.
