Growth of obligate anaerobes. The mixture of necessary nutrients can be used as a liquid medium, or a solidifying agent can be added. Agar agar is a natural polysaccharide produced by marine algae and is the most commonly used solidifying agent added to media (end concentration usually 1.5 % w/v). If hydrolysis of the agar is suspected, a silica gel is used as a replacement solidifying agent.
This list of simple media is all you need to maintain a culture collection. At the peak, in 1985, my collection of microbial cultures had 2000 strains of 250 species. These are the only media I used for stock cultures. ** marks the media I use for many species, * marks media I use for a few species.I needed the other media only for rare species. Notice the abbreviation listed before each medium. I mark that abbreviation on each tube of the medium and use it on all my web pages.A Nutrient Agar. Supports the growth of many common bacteria from the intestines and many other species. Nutrient agar is the most widely used medium in highschools, but not in my laboratory. TGY supports the growth of many more species.
