I want to investigate the type of bacteria present in skin. But I want to know what type of medium are available as culturing medium. Please identify a bacteria and its culturing medium and composition of the agar nutrient. State the website or sources so I can follow up and thanks a lot for any help.

agar is a product obtained from several species of red algae, or seaweed, chiefly from the Ceylon, or Jaffna, moss (Gracilaria lichenoides) and species of Gelidium, harvested in eastern Asia and California. Chemically, agar is a polymer made up of subunits of the sugar galactose; it is a component of the algae's cell walls. Dissolved in boiling water and cooled, agar becomes gelatinous; its chief uses are as a culture medium (particularly for bacteria) and as a laxative, but it serves also as a thickening for soups and sauces, in jellies and ice cream, in cosmetics, for clarifying beverages, and for sizing fabrics.

If you want to culture skin bacteria, pretty much any of the standard culture media will work quite well. The most common ones are "nutrient agar" and "tryptic soy agar". There are hundreds of different media available commercially, but these should work for what your trying to grow quite nicely. Any biological supply company will have these.

trypticase soy agar with 5% sheep's blood will grow just about anything found on the skin.
