[45] Sodium-driven flagellar motors of alkalophilic Bacillus

摘要: Publisher Summary This chapter describes the method to measure motility and bioenergetic parameters of alkalophilic Bacillus. Although flagellar motors these bacteria require Na + for their rotation speed is optimal under alkaline conditions, swimming pattern are indistinguishable from those neutrophilic Bacillus such as B. subtilis. Hence, most methods measurements also utilizable Bacteria swim by rotating flagella, each flagellum driven at its base a rotary motor embedded in cell wall cytoplasmic membrane. In case Escherichia coli subtilis , which living moderate energy supplied electrochemical potential gradient protons across membrane—namely, protonmotive force. Recent studies indicate that presence essential motors. Thus, strains considered have -driven
