Electron Transport Chain of Bacteria (With Diagram)

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 [...]

Genetic Recombination of Bacteria: 3 Processes

The following points highlight the three main processes involved in the genetic recombination of bacteria. The processes are: 1. Conjugation 2. Transformation 3. Transduction. Process # 1. Conjugation: Lederberg and Tatum (1946) discovered conjugation in E. coli and its detailed studies were made by Woolman and Jacob (1956). Conjugation, is a process by which genetic material is transferred from one [...]

Common Examples of Cyanobacteria (With Diagram)

The following points highlight the two common examples of Cyanobacteria. The examples are: 1. Spirulina and 2. Nostoc. Spirulina: It is a spirally coiled free floating filamentous blue green alga or cyanobacterium of up to 0.5 mm length. The trachoma's appear to be unicellular but staining and electron microscopy has shown the presence of thin transverse walls. The ends are [...]
