All organisms require an energy source to drive energy-consuming life processes. Energy can be tapped from light or chemicals (organic chemicals and inorganic chemicals). Organisms that can utilize...

pH scale is used to express the acidity or alkalinity of a solution on which neutrality is pH 7. The pH scale extends from pH 0.0 to pH 14.0, and each pH unit represents a tenfold change in hydrogen...
Microbes are loosely classified into several groups based on their preferred temperature ranges. Every organism has a range of permissive growth temperatures. Unlike pH or osmolarity, microbes...
When bacteria are inoculated into a suitable culture media into an enclosed vessel, such as a tube or a flask, and incubated, their growth follows a definite course. A bacterial growth curve is...
Microorganisms can be characterized by their requirements for oxygen. The oxygen requirements of bacteria reflect the mechanism used to satisfy their energy needs. Depending on the oxygen...
