Explain how hypertonicity can be used as a means of controlling microbial growth?

Hypertonic is net movement of water out of the cell. Cells lose water by osmosis and becomes shriveled which can cause plasmolysis; inhibits cell production.

A surface chemical that prevents microbial growth is?
interferon
How can microorganisms be controlled?
Inhibiting microbial growth is thus achieved in one of two ways: select bacteria can be either totally killed, in a process known as bactericide, or the growth of the cells can be stunted severely, in what is called a bacteriostatic process.
What is the use of a refrigerator in microbiology?
it is used to preserve media or chemical reagents. if microbial samples were present, it slows down its metabolism. if the microbial samples were psychrophiles, it enhances their growth.
Discuss a bacterial growth curve and phases of bacterial growth?
The bacterial growth curve is usually exponential in shape just like most of the living organism.
Under what kind of plating technique would you find deep or buried colonies?
In pour plate method, in this method of plating or culturing the microbial sample first diluted and pour in empty plate and after that growth media is poured in it and which is then skake firmly. As the microbial suspension or sample is distributed in media the growth of bacteria occurs in buried of deep positions.
Definition of microbial growth?
microbial growth is the multiplying by dividing of micro-organisms such as bacteria, algae, fungi etc.
What is microbiostatic?
Inhibits microbial growth
What has the author Allen I Laskin written?
Allen I. Laskin has written: 'Advances in Applied Microbiology' 'Growth and metabolism' -- subject(s): Microbial growth, Microbial metabolism 'Nucleic acid biosynthesis' -- subject(s): Nucleic acids, Synthesis 'Microbial metabolism, genetics, and immunology' -- subject(s): Immunology, Microbial genetics, Microbial metabolism 'Microbial products' -- subject(s): Microbial products, Tables
What is Exponential growth phase of microbial growth?
When the bacteria double at a constant rate
A surface chemical that prevents microbial growth is?
interferon
Do microbial growth refers to a population and not to an individual cell?
A cell
Define oligodynamic action?
its the microbial growth inhibition by heavy metal ions
Example of microbial contamination?
Microbial contamination is the introduction and growth of harmful microorganisms in foods and water, causing food borne illness and even death. Some examples of microbial contamination include botulism, salmonella, and mold.
Is sodium a preservative?
Yes, it can be used as a food preservative, primarily by inhibiting microbial growth.

What inhibits microbial growth at nonoptimal?
Both acidity and alkalinity can inhibit microbial growth. Acid is often used in food as a preservative to prevent microbial growth.
