Best Answer

Autoclaving media twice may result in nutrient loss and changes in pH and composition which can affect microbial growth. It is generally recommended to prepare fresh media for each use to ensure optimal conditions for microbial growth.

What type of media are sterilized in the autoclave?

PBS can be safely autoclaved. It only contains inorganic salts, which are quite heat-stable. AFAIK media can not be autoclaved, because there are many different (organic) compounds in them, which would be lost because of the heating. One way you can save money, is to prepare media from powder, sterile filter large amounts (like 20 l or so) with one bottletop filter and store in 1 l sterile bottles. You have to add (sterile) glutamine and FBS (and whatever else you want) when you open the bottle.
