What does a culture medium provide to a living thing?
Culture media in microbiology is a media where microorganisms like bacteria from a sample is grown into colony for the identification of particular organism.eg-simple media like blood agar,choclate agar
How do you test if the medium is free from contamination?
One way to test if the medium is free from contamination is to streak a sample of the medium onto agar plates and incubate them. Monitor the plates for any growth of unwanted microorganisms. Additionally, perform a gram stain or use selective media to further confirm the absence of contaminants. Regularly checking the medium under a microscope for any signs of microbial growth can also help ensure its purity.
How are isolation techniques affected by selective mediums?
Isolation techniques are affected by selective mediums because they contain components that inhibit the growth of certain microorganisms while promoting the growth of others. This helps in isolating specific types of microorganisms from a sample by creating conditions that favor their growth and suppress the growth of unwanted organisms. Selective mediums are designed to enhance the isolation of target microorganisms by creating an environment where they can outcompete other organisms present in the sample.
What is a culture plate used for?
A culture plate is used in microbiology to grow and isolate microorganisms, such as bacteria and fungi, from samples. It typically contains a solid growth medium, like agar, that provides nutrients and a suitable environment for the organisms to proliferate. Researchers can observe colony characteristics, perform biochemical tests, and conduct further analyses to identify or study the microorganisms present in the sample.
A small sample taken from the body and placed on a medium to allow bacteria growth is a?
A small sample taken from the body and placed on a medium to allow bacteria growth is called a culture. This process helps identify and analyze the type of bacteria present in the sample, which is crucial for effective diagnosis and treatment of infections.

Why is it that dried food sample can contain lower numbers of microorganisms?
Drying food removes moisture, which is essential for microbial growth. Without water, microorganisms struggle to survive, reducing their numbers in dried food samples. Additionally, drying can also disrupt the cellular structure of microorganisms, further inhibiting their growth and proliferation.

Definition of a hibitory substance relative to a water sample?
A hibitory substance relative to a water sample is a substance that allows for the growth of microorganisms. This would be like a contamination of water that can cause disease to spread.
What are the five I's in microbiology?
The five I's in microbiology are: Inoculation (introducing a sample into a container of growth medium), Incubation (allowing the microorganisms to multiply), Isolation (separating and obtaining a pure culture), Inspection (observing the characteristics of the microorganisms), and Identification (determining the specific species of the microorganism).

What is the purpose of the streak for isolation?
By using streak plate technique to spread a clinical sample out on the surface of a growth medium individual types of bacteria can be isolated
How chloroform helps to preserve the water sample?
Chloroform can help preserve a water sample by inhibiting the growth of bacteria and microbes that could degrade the sample. It acts as a disinfectant by disrupting the cell membranes of microorganisms, preventing them from multiplying and breaking down the organic matter in the sample. This preservation method allows for more accurate testing and analysis of the water sample over an extended period of time.
The term culture refers to the rapid growth of microorganisms in a what?
Microbial culture helps to detrmine the type of organism or the abundance in a sample. It is the multiplication of microbes by allowing them to reproduce in a culture media under laboratory conditions.
Function of nutrient broth?
There are various types of nutrient broth, some selective, some not so. They are basically a liquid culture medium to enhance the growth of mircoorganisms from a sample, be it a human clincal sample, food, environmental sample or whatever. After the nutrient broth has been inoculated with the foresaid sample, it is generally incubated for a given length of time to encourage the growth of whatever is in the sample then identified.
