 Agar - Wikipedia, the free encyclopedia
Chemically, agar is a polymer made up of subunits of the sugar galactose; it is a component of the algae's cell walls.
Research grade agar is used extensively in plant biology as it is supplemented with a nutrient and vitamin mixture that allows for seedling germination in petri dishes under sterile conditions (given that the seeds are sterilized as well).
Nutrient agar is used throughout the world as a medium for the growth of bacteria and fungi, but not viruses (however, viruses are often grown in bacteria that are growing on agar).

The agar solution doesn't necessarily need to be boiled to dissolve (as a first step); as long as it is thoroughly mixed, the autoclave's heat and boiling of the water during sterilization will cause it to go into solution.
From distant memory, when looking for most human pathogens, plates are incubated for two days in total, although many are looked at after one day, before being reincubated.
For slower growing pathogens (e.g Campylobacter, Bordetella), plates are sometimes incubated for longer.
