After "pooling" class data, circle the TDT (first time with no growth) and TDP (first tem- perature with no growth) for each organism. OBSERVATIONS Assigned temperature Table #1-50°C Table #2-60°C Table #3-70°C Table #4-80°C Thermal Death: Time (TDT) Thermal Death: Point (TDP) 10 min 30 min. 50 min 10 min 30 min 50 min = 10 min 30 min 50 min 10 min 30 min 50 min E. coli 20 min 40 min. 20 min 40 min 20 min 40 min 20 min 40 min Thermal Death Time Constant temperature Thermal Death Point Variable temperature 10 min 30 min 50 min 10 min 30 min 50 min 10 min 30 min 50 min + = GROWTH 0 NO GROWTH S. aureus 10 min 30 min 50 min 20 min 40 min 20 min 40 min 20 min 40 min 20 min 40 min Variable length of time Constant length of time 10 min 30 min 50 min 10 min 30 min 50 min 10 min 30 min 50 min 10 min 30 min 50 min B. cereus- 20 min 40 min 20 min 40 min 20 min 40 min 20 min 40 min 1.
