Swarming Motility and Biofilm Characterization of the yisR Mutant of Bacillus subtilis


Mansi Trivedi* and Matthew Berrois
Dr. Joyce Patrick, Faculty Mentor

Bacillus subtilis is a Gram positive bacteria that is a model for swarming motility, biofilm formation, and sporulation. Swarming is a mode of motility for B. subtilis that involves coordinated migration over a surface. In previous studies, a yisR mutant has shown growth defects in nutrient limited conditions.While trying to conduct a genetic screen to identify genes that work in the same pathway as yisR, we discovered that yisR mutants had a swarming defect. Swarming and biofilm formation are inversely regulated, such that genes that promote swarming inhibit biofilm formation and visa versa. Currently we are focused on measuring the swarming and biofilm formation phenotypes of the yisR mutant.
