The below mentioned article provides a quick note on the Respiration in Bacteria. According to the mode of respiration, bacteria can be aerobic or anaerobic. Each of them is further of two types, obligate and facultative. Aerobic: (a) Obligate Aerobes: They are bacteria which can respire only aerobically. They generally get killed under anaerobic conditions, e.g., Bacillus subtilis. (b) [...]
The below mentioned article provides a quick note on the Sporulation of Bacteria. Bacteria produce several types of spores called gonidia, sporangiospores, arthrospores (oidia), conidia, cysts and endospores. Endospores (Fig. 2.12): They are highly thick-walled and resistant spores which are formed in response to adverse environment, presence of harmful waste products or ageing of bacterial colony. A part of protoplast [...]
The following points highlight the three methods of Sexual Reproduction (Para Sexuality) in Bacteria. The methods are: 1. Conjugation 2. Transformation 3. Transduction. Method # 1. Conjugation: It was first discovered in Escherichia coli by Lederberg and Tatum (1946). They found that two different types of auxotroph (nutritional mutants) grown together on minimal medium produced an occasional prototroph (wild type). [...]
