The survival of microorganisms in the laboratory as well as in nature depends on their ability to grow under certain chemical and physical conditions. An understanding of these conditions enables us to characterize isolates and differentiate between different types of bacteria. Such knowledge can also be applied to control the growth of microorganisms in practical situations. Organisms that are generally organotrophic, may also be termed chemoorganotrophs. These organisms may use a variety of organic compounds as both carbon and energy sources. A common sugar used is glucose. ATP is generated by either substrate-level or oxidative phosphorylation.
