Viruses are basically genetic information (DNA or RNA) inside a protein coat (capsid). They cannot grow unless they are inside of a host cell (your body).
So as a note...viruses are not grown in agar...but the bacteria they are grown inside of may have been grown in agar.

They are not technically alive, and neither are replicating capsids like Anthrax (Mad Cow Disease).
Bacteria can grow on enriched Agar because bacteria are cells, they require some form of nutrition to metabolise/respirate, produce waste and reproduce. Viruses commandeer (think, as in demon possession) a living cell, causing the cell to behave oddly and spit out lots of virus spawn. The commandeered cell has been genetically reprogrammed into a "virus factory."
Now, if a bacterial culture on enriched Agar becomes infected by a virus (all it takes is one) then that virus could take over the whole sample and multiply until all the infected cells have died giving birth to the ingrateful little sprogs. The end result could be a population of dead bacterial cells and an even higher population of active (eligible bachelor?) viruses in yer little petri dish. Horror of horrors!

∙ 12y agoNo, Viruses are obligate intracellular parasites and require a living host for growth. So, they can't be grown on any artificial growth medium including agar.

What is the composition of modified nutrient glucose agar media?
Modified nutrient glucose agar is composed of agar, water, glucose, extracts, peptone and sodium chloride. Modified nutrient glucose agar allows organisms to grow.
Can vibrio parahaemolyticus grow on nutrient agar?
what ever you grow it in needs a relatively high salinity
Does Bacillus subtilis grow in MacConkey broth?
Bacillus subtilis is grown on nutrient agar or in nutrient broth. The preferred medium is M9 with glucose.
What organisms don't grow on broad spectrum nutrient agar?
In my experiments of growing cultures on agar plates, I found Nutrient Agar's usually grow mostly molds and fungi. It's bacteriological growth is wide, yes, but I found that even after a few uses it started growing specifics (mostly gram negative coccus and bacillus).
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.
If an organism can grow on both a nutrient agar and a MacConkey Agar on which would you expect it to grow better?
The organism would be expected to grow better in nutrient agar. Nutrient agar is rich in nutrients and microorganisms grow well when there is availability of nutrients.
What is the composition of modified nutrient glucose agar media?
Modified nutrient glucose agar is composed of agar, water, glucose, extracts, peptone and sodium chloride. Modified nutrient glucose agar allows organisms to grow.

Why is the nutrient agar used?
In Microbiology? Because the nutrient agar allows for the bacteria/organisms to grow in a controlled environment/substance. It also allows you to monitor the growth.
What will grow pink or red colonies on nutrient agar?
micro coccus Species
What microorganism can grow on a malt agar?
Bacillus subtilis E. coli Pseudomons fluorenscens streptococcus faecilis most bacteria can grow on nutrient agar
What kind of agar should be used to grow bacteria from hands before and after washing for a grade 8 science fair?
blood or nutrient agar would work, but blood agar will most likely grow more bacteria.
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.
Does Bacillus subtilis grow in MacConkey broth?

What types of bacteria do not grow on nutrient agar?
Most of Gram+ bacteria and for Gram- ones, Segnilliparus spp.
