In this article some important principles are undertaken so that we can well understand the various mechanisms of energy conservation. Free Energy: In microbiology, energy is measured in units of kilojoules (kJ), a measure of heat energy. Chemical reactions are accompanied by changes in energy. Although in any chemical reaction some energy is lost as heat, in microbiology the interest [...]
In this article we will discuss about the infection cycles of lytic, single-stranded and temperate bacteriophages. Infection Cycle of Lytic Bacteriophages: The lytic cycle of these bacteriophages can be divided into several stages, like attachment and adsorption, penetration, intercellular changes resulting in the synthesis of viral components, assembly of progeny virions and release from the infected cell. These steps are [...]
In this article we will discuss about the preparation of preservatives which is capable of preventing microbial infection. Formaldehyde Solution: Formaldehyde is a volatile substance. The maximum concentration can be manufactured is 40%. In preservation, commercial grade formaldehyde is used. Strength of the solution is calculated on the basis of 40 ml reagent in 100 ml formaldehyde available in the [...]
