Culture Techniques
 
 
- Aseptic- allow handling of materials without the introduction of contaminants for growth of pure cultures (Koch’s Postulates)
- 
- minimize contact with room air and non-sterile surfaces.  Keep petri dishes & test tubes closed.  Sterilize forcepts, loops, wires, etc...
 
- Agar- solidifying agent (not nutrient).  Melts at 100o and solidifies at 45oC.
