Why are some bacteria able to grow on count agar that contains milk even though they do not produce any proteases?
Because plate count agar is still agar. therefore, it still has all the nutrients that bacteria require to grow.
Macconkey agar is a selective medium and it is also a defined or a undefined medium so why is that a formulation desirable?
This type of agar is designed to grow gram-negative bacteria. It will not grow gram-positive bacteria due to a dye in the formula of the agar.
What equipment can be used to grow bacteria?
Agar and petri dishes.
How does nutrient agar work?
Agar is a gelatinous substance procured from algae, and used in bacteria cultures. It works simply to feed the bacteria and let it grow rapidly.
What the most common way to grow bacteria is?
The most common way to grow bacteria is in an agar petri dish. The bacteria are usually placed by a swab into the petri dish and incubated for a predetermined period of time (The agar serves as a food source for the bacteria). Then, growth, or no growth, of bacteria will be observed.
What type of semisolid medium is used to grow bacteria?
Agar is a semi solid medium used to grow bacteria.
What does it mean to inoculate an agar plate?
to inoculate an agar plate you would place bacteria on the agar to grow
Why does gram-positive bacteria grow in mannitol agar?
Gram-positive bacteria grows in Mannitol agar because it contains a high level of salt. This type of agar allows only certain types of bacteria to grow, making it selective.Ê
What do scientists grow bacteria on?

Why are there areas on the agar jelly where no bacteria are growing?

What kind of agar should be used to grow bacteria from hands before and after washing for a grade 8 science fair?

What workplace uses agar?
Agar is a solid form of nutrient for different strains of bacteria. Anyone who needs to grow bacteria for use in their labs or experiments would use agar.
Why did you stab the peptone iron agar instead of inoculating only the surface?
Because the peptone iron agar is used to detect ANAEROBIC bacteria. If you stab it deep into the agar you allow the bacteria to grow in the absence of oxygen. If you only inoculated the surface the bacteria wouldn't grow.

Is glucose salts agar selective?
Glucose Salts Agar (GSA) is a selective agar that selects for gram-negative bacteria only. This means that no gram-positive bacteria will be able to grow on it.
