S-Layer Increases Predation Ability Of Myxococcus Xanthus
S-Layer Increases Predation Ability Of Myxococcus Xanthus
Symposium of Student Scholars
Background: Myxococcus xanthus is a gram-negative soil bacterium that exhibits micro-predatory activities. When starved, M. xanthus produces resistant spores within fruiting bodies for survival. The S-layer is a paracrystalline structure intertwined in many different patterns and is composed of proteins or glycoproteins. A species that produces the S-layer is Aeromonas. A. salmonicida is a strain of Aeromonas that infects fish. A. hydrophila is another pathogenic strain that causes a wide range of human diseases. We investigated the ability of the S-layer to protect Aeromonas from predation by Myxobacteria. Methods: Myxococcus and prey Aeromonas cultures were standardized to a concentration …
Evaluating Volatile Organic Compounds For Contact-Independent Antagonism Of Pseudogymnoascus Destructans
Symposium of Student Scholars
White-nose syndrome (WNS), a disease caused by the fungus Pseudogymnoascus destructans, is responsible for the extensive mortality of bats in the United States. In an effort to develop tools to reduce bat mortality attributed to WNS, an in vitro experiment was conducted to quantify the inhibitory effects of select volatile organic compounds (VOCs) as well as explore potential synergistic activities. The experiment involved exposing mycelial plugs of P. destructans to various concentrations of B23 as well as B23 and decanal together at equimolar ratios. Measurements of the plugs were taken over the course of the 13 day experiment allowing …
