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.
我们研究了大肠杆菌在不同重力强度下的生长情况和蛋白质谱，以确定超重力对生化反应的影响。大肠杆菌在低于7500克的重力下生长不受抑制。超重力诱导了外膜孔蛋白W（OmpW）和抗原43的产生。重力强度的变化改变了这些蛋白质的表达水平。这表明超重力可调节细菌中的基因表达。
