Question

THe hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of __________ hemolysis on a blood agar plate

Answer 1

The hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of beta hemolysis on a blood agar plate.

Step-by-step explanation:

Triglyceride hidrolysis is the breakdown of lipids made by certain types of bacteria, which have the enzyme lipase. It is sometimes desirable in a laboratory to identify whether these bacteria are in a particular culture medium. For this reason spirit blue agar, which is a reagent with a high concentration of lipids, is added to this culture medium. If bacteria that break lipids are present in this culture medium, they will break the lipids present in spirit blue agar and this will give their colonies a look that will make it easier for scientists to see and identify these bacteria.

This process is similar to what is done as it is desirable to identify bacteria that cause beta hemolysis, which is the breakdown of red blood cells. in which case blood agar is added to the culture medium which has a high concentration of red blood cells. If these bacteria are present in the culture medium, they will cause hemolysis of the red blood cells present in the blood agar and this will give the colonies an appearance that will facilitate the visualization and identification of these bacteria by the scientists.

Answer 2

The hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of beta hemolysis on a blood agar plate.

The hydrolysis of triglycerides on a spirit blue agar plate is used for identifying bacteria based on what organic compounds they can break down, in this case lipids. Spirit blue agar is a medium that contains a supply of lipids. If bacteria have lipase, the enzyme capable of breaking down lipids spirit blue agar will be digested and it will appear as a halos around colonies of bacteria that make lipase.

The ability of bacterial colonies to induce hemolysis (the breakage of red blood cells) when grown on blood agar is used to identify microorganisms. Beta hemolysis is a complete lysis of red blood cells and in the blood agar, that area under the colonies that do the hemolysis appears lightened and transparent.
