One primary difference between the quadrant streak procedure and the spread plate procedure is the quadrant streak method uses an undiluted sample to inoculate the agar plate and the spread plate method uses a diluted sample to inoculate the agar plate. The streak plate method relies primarily on the physical streaking technique to produce isolated colonies and the spread plate method relies primarily on a properly dilutes sample. After both techniques are utilized and growth has occurred, isolated colonies can be used to begin a pure culture on new sterile medium. All of the above.

1. EXPLAIN the difference between a mixed culture versus a pure culture. 2. What is the purpose of doing a streak plate isolation? 3. EXPLAIN why colony forming unit (CFU) is a more correct description of the colony origin. 4. Give two reasons when one should one do a quadrant or T-streak on a bacterial sample. 5. Give two reasons when one should one do a zig-zag streak on a bacterial sample. 6. When performing a quadrant streak which quadrant (1,2,3 or 4) will have the most bacteria? Which quadrant should have the least amount of bacteria? 7. When performing a quadrant or T-streak, some microbiologists prefer to lift the lid of the plate off slightly and hover it over the plate. Why is this done?

In a transformation experiment, a sample of E. coli bacteria was mixed with a plasmid containing the gene for resistance to the antibiotic ampicillin (ampr). Plasmid was not added to the second sample. Samples were plated on nutrient agar plates, some of which were supplemented with the antibiotic ampicillin. The results of E. coli growth are summarized below. The shaded area represents extensive growth of bacteria; dots represent individual colonies of bacteria. Plates that have only ampicillin resistant bacteria include which of the following? a. I only b. III only c. IV only d. I and II
