Whenever possible why should you avoid sharing bunsen burners or incinerators. A defined medium is synthesized from individual chemicals required by the organism so the exact molecular composition is known whereas an undefined medium is made from natural products such as yeast extract where the precise composition is unknown. Bacara agar plates chromogenic media prepared plates or flasks purchased from aes chemunex cranbury nj.

A sample from an environmental surface is placed on an agar plate containing growth medium. Area of initial inoculation and first streaks yields heavy growth. You can see the crater in the center of this pic. Pour 18 20 ml nutrient agar into sterile 15 100 mm petri dishes.
