In the environment, microbes have adapted to the habitats most suitable for their needs, in the laboratory, however, these requirements must be met by a culture medium. A microbiological culture,...

Microbial growth depends on the metabolism of nutrients, and results in the formation of a discrete colony, an aggregation of cells arising from a single parent cell. A nutrient is any chemical required for growth...

Microbial Nutrition and Metabolism All living organisms require nutrients from the environment for the synthesis of their cell materials and for the generation of energy. Micro-organisms are extraordinarily diverse in their specific physiological properties and correspondingly differ in their specific nutrient requirements as well as their adaptation to the physical...
