Answer:
All types of living organisms use cellular respiration for the production of energy from food molecules such as glucose.
Explanation:
Respiration is energy releasing process which occurs in mitochondria of the cell. Respiration has two types i. e. Aerobic and anaerobic respiration. In aerobic respiration, energy is released from the breakdown of glucose molecules with the addition of oxygen while anaerobic respiration is the release of energy from breakdown of glucose molecules without the use of oxygen.
The four groups of pathogenic E.coli are enteropathogenic, enterotoxigenic, verocytotoxigenic and enteroinvasive groups. These groups can best be isolated and recoved through luria broth.
<h3>What is Escherichia coli?</h3>
The pathogenic E. coli or Escherichia coli serotypes are grouped on the basis of their mechanism of causing symptoms in humans. The six groups of pathogenic E.coli are enteropathogenic, enterotoxigenic, verocytotoxigenic, enteroinvasive, enteroaggregative and diffusely adherent E. coli.
Luria broth (LB) is one of the most commonly used growth medium for E. coli. It promotes fast growth of the organism and also provides good plasmid yields, making it an excellent choice for most laboratory applications, especially the small-scale plasmid preps.
