They are pervasive and play many different roles in the marine environment, from being the base of the food chain, controlling much of the flow of marine energy and nutrients, and being essential to the ocean's health.
Answer:
A serial dilution and the following plating experiment is done in order to determine the actual amount of bacteria/microbes in a specific volume of soil sample. As a standard test, a set volume of the lower dilution is obtained and positioned on a median plate and permitted to increase for the needed amount of time. The amount of colonies is evaluated and thus the overall Colony Forming Units (CFU) is determined by unit volume of the sample plated and therefore the volume of soil sample employed.
Therefore,
The calculation is done using:
CFU/ml = Number of colonies appeared × dilution factor / volume plated
Given,
Number of colonies appeared = 97
dilution factor = 10^(-6)
volume plated = 1/10 = 0.1
This will help us calculate it as:
CFU/ml = 97 * 10^(-6) / 0.1
= 97 * 10^(-7) CFU/ml
This CFU/ml helps determine the amount of bacterial colonies per unit volume of sample plated.
Given,
The original sample as 1g or 1000 mg of soil in its total volume.
Therefore,
The number of bacteria can be calculated using:
Amount of bacteria in original sample
= 97 * 10^(-7) CFU/ml × 1/ 1000 mg
= 9.7 * 10^(-3) CFU/mg
Dab most likely inhibits phosphorolysis of glycogen reaction.
<h3>What is
phosphorolysis?</h3>
- Inorganic phosphate acts as the attacking group during phosphorolysis, which is the cleavage of a molecule.
- It's comparable to hydrolysis.
- A reversible process akin to hydrolysis where phosphoric acid behaves like water and produces phosphate as a byproduct.
- It's comparable to hydrolysis.
- Glycogen phosphorylase, which catalyzes the assault of inorganic phosphate on the terminal glycosyl residue at the nonreducing end of a glycogen molecule, is an example of this.
- The difference is that while reactions involving hydrolysis use water to split larger molecules into smaller ones, reactions involving phosphorolysis use phosphate to achieve the same result.
- The primary enzyme in utilizing the glycogen reserves in the muscle and liver is known as glycogen phosphorylase.
- It catalyzes the sequential phosphorolysis of glycogen to liberate glucose-1-phosphate.
