Detailed explanation-1: -The bacteria are killed at cooking temperatures, but the spores they produce are able to survive brief heating to 100oC and may actually be stimulated to germinate by the heat.
Detailed explanation-2: -Temperatures of 110°C will kill most Bacillus spores within a short time. In the case of Clostridium temperatures of up to 121°C are needed to kill the spores within a relatively short time.
Detailed explanation-3: -Pathogenic bacteria grow quickly in food at temperatures between 40 to 140°F (5 to 60°C) . In order to kill these bacteria, it’s important to cook all foods to a safe internal temperature. The CDC lists the following temperature guidelines for several common types of food: poultry, whole or ground: 165°F (74°C)
Detailed explanation-4: -5.4 Thermophiles. Thermophiles are those organisms which grow above 40 °C, and which have optimal growth temperatures between 50 and 55 °C (Gleeson et al., 2013).
