title: Gravity sensing by Escherichia coli.
abstract: We investigated the growth and protein profile of Escherichia coli under various gravity strengths to determine the effects of hypergravity on biochemical reactions. E. coli grows at less than 7,500 g without inhibition. Hypergravity induced OmpW and Antigen 43. Changes in gravity strength altered the expression levels of these proteins. This suggests that hypergravity regulates gene expression in bacteria.
