The following points highlight the three main types of growth that take place in bacteria. The types are: 1. Diauxic Growth 2. Synchronous Growth 3. Continuous Growth. Type # 1. Diauxic Growth (Diphasic Growth): Diauxic growth is a diphasic growth represented by two growth curves intervened by a short lag phase produced by an organism utilizing two different substrates, one [...]
In this article we will discuss about the generation time of bacteria. Most bacteria reproduce by binary fission, which results in doubling of the number of viable bacterial cells. Therefore, during active bacterial growth, the number of bacterial cells and, hence their population, continuously doubles at specific time intervals because each binary fission takes a specific duration of time. This [...]
Learn about the comparison between moist heat sterilization and dry heat sterilization. Microorganisms are killed by heat as a result of the inactivation of their proteins (including enzymes) and, as stated earlier, the heat is applied either in moist or in dry conditions in processes of sterilization called moist heat sterilization and dry heat sterilization, respectively. The conditions and mechanisms [...]
