Do bacteria swim?

“For bacteria to swim in water,” explained Jay Tang, associate professor of physics at Brown University, “it's like us trying to swim through honey. The drag is dominant.” Tang and his team at Brown have just completed the most detailed study of the swimming patterns of one particular bacterium, Caulobacter crescentus.

How does a bacteria maintain homeostasis?

Homeostasis refers to self-regulating processes that living organisms use to maintain their internal stability, thus guaranteeing their survival. The main homeostatic processes that guarantee the survival of bacteria include iron and metal homeostasis, pH homeostasis and membrane lipid homeostasis.
