The term fastidiousness refers to the complexity of an organism's nutritional requirements. A fastidious microorganism will only grow if the culture medium provides the necessary nutrients. This table provides the readings on the optical density from bacterial cultures. This reading gives an indication of the concentration of the bacteria in the culture; the higher the concentration of bacteria, the greater scatter of light and the higher value of optical density. Yeast extract broth, nutrient broth and glucose broth are culture media which are enriched with more nutrients. In all these three media, <em>S.mitis</em> had the lowest optical density, meaning the lowest concentration. We can conclude that <em>S.mitis</em> is the most fastidious microorganism of the three. Then comes <em>A.faecalis</em> and the least fastidious of the three is <em>E.coli.</em>
It is extremely labor intensive and costly. :-(

Answer:
a. lactic acid fermentation
Explanation:
Under conditions of intense exercise, the oxygen gas obtained by pulmonary respiration may be insufficient to meet the needs of muscle cells in the work of obtaining energy from cellular respiration.
However, even in the absence of oxygen gas, our muscle cells can release the available energy in glucose, leading to even smaller amounts of ATP molecules. Under these conditions, muscle cells perform lactic fermentation, a process that is virtually identical to glycolysis (the first set of cellular respiration reactions), except that pyruvic acid is transformed into lactic acid with the formation of 2 ATPs. Despite the lower energy yield, fermentation ensures the energy supply to the muscle. Lactic acid formed under these conditions has been associated with muscle pain and fatigue characteristic of intense physical exercise. Recent research, however, has shown that pain is caused by muscle fiber micro-injuries rather than lactic acid as it is rapidly metabolized and eliminated.
