Are the dehydration reactions and form water molecules.
Explanation:
Polymerization reactions are the ones that join two monomers together by the formation of a covalent bond between them. Examples include the formation of a glycosidic bond between two simple sugars to join them and form a disaccharide. During the polymerization, one water molecule is formed for each of the glycosidic bonds formed.
Likewise, when two amino acids are joined together by a peptide bond, a dipeptide is formed and one water molecule is formed. These reactions are categorized as dehydration reactions as they remove one water molecule from two monomers.
The name given to these specific polymerization reactions where monomers of macromolecules, as monosaccharides and amino acids are synthesized to form polysaccharides and proteins would be dehydration synthesis reactions or condensation reactions.
Psychrotrophs are those bacteria which can tolerate cold temperature and have optimum growth above 15 degree Celsius.
Halophiles prefer high salt concentration.
Mesophiles prefer temperatures with a average of 37 degree Celsius.
Anaerobes grow in absence of oxygen.
In the given experiment, none of the bacterial cultures were placed in saline or anaerobic conditions. So, the bacterial species is not an anaerobe or halophile.
Again the cultures did not show growth at 37 degree celsius so they are not mesophiles.
Maximum growth at 22 degree celsius and a little growth in refrigerator make it obvious that the species is a Psychrotroph.
