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 [...]
The electron transport chains of bacteria (prokaryotes) operate in plasma membrane (mitochondria are absent in prokaryotes). Some bacterial electron transport chains resemble the mitochondrial electron transport chain. Paracoccus denitrificans is a gram-negative, facultative anaerobic soil bacterium. It is a model prokaryote for studies of respiration. When this bacterium grows aerobically, its electron transport chain possesses four complexes that correspond to [...]
