BIOL 3200 Lecture Notes - Lecture 8: Heliobacteria, Petri Dish, Flow Cytometry
Document Summary
Pressure barophillic: needs high pressure barotolerant: can survive through pressure changes osmotic pressure: can survive in high osmotic pressure; works by adding salt halophilic: requires high salt level halotolerant: they survive with high osmotic pressure but isn"t required. Aerobic: needs free o2 micro aerobe: needs small amount of free )2. Aerobe: needs no free o2 obligate: can"t tolerate o2 at all facultative: grow and reproduce better without oxygen, but it doesn"t help them cahophile: requires lots of co2. Filter into a sterile flask (drawing) to count the cells: A. pull the filter out and count. B. put filter on agar plate and incubate, then count colonies. Mixed culture of bacteria stain with different stains. Theres a meter, flask, and light (drawing) If it grows in a liquid: filter cells, rinse 3 times, dry, weigh (mass per individual cell)
