Is agar the only medium to culture bacteria?

What is the simplest way of preparing a bacterial culture?

Is agar the only medium to culture bacteria?
i would say get some sterile water (clean water - free from any microorganisms) and add some pure sugar into it !!





here you go !! bacteria will live beutifully there untill the sugar is all used up ...





[dont put too much sugar, as this can kill everything there .. too much sugar will cause the cells to burst, and by the way this is why jams/honey ...etc is hard to grow any bacteria on (except fungi ofcourse)
Reply:Nope. Gelatin is a real good one too. It's also available in a film, cut to fit a petri dish. You need to get your hands on a laboratory supply catalogue.
Reply:The simplest way is probably in a broth: take a colony from an agar plate and dip it into some liquid medium (eg nutrient broth or LB). I think you can also grow it on collagen with a liquid medium, or gelatin.
