Biophysics confinement microbiology microfluidics bacterial growth and movement in confined spaces is ubiquitous in nature and plays an important role in diverse fields ranging from soil microbiology, water purification, to microbial pathogenesis.
During batch culture, a typical bacterial growth curve shows five distinct phases of growth: lag phase, the delay before the start of exponential growth exponential phase, where cell division proceeds at a constant rate stationary phase, when conditions become unfavorable for growth and bacteria. The study of microorganisms is greatly facilitated if we are able to culture them, that is, to keep reproducing populations alive under laboratory conditions.
