Our results are based on theory, as stated above, and experimental evidence. The spot plate was labeled in time intervals each two minutes apart. If lab assistants do not prepare the meat solution, a mortar, pestle and cheese-cloth is needed.
Add 1 mL of the buffer solutions as indicated in Use a mortar and pestle to macerate a marble size portion of fresh, raw ground meat in 10mL of distilled water. No catalase is added to tubes 1,3,9 or 10 Figure 2.
Once we did that, the new data fit nicely into the trend.
