Bacterial spores are the most dormant form of bacteria since they exhibit minimal metabolism and respiration, as well as reduced enzyme production. In order to kill these bacteria, its important to cook all foods to a safe internal temperature. Several types of disease-causing organisms can be present in water, including bacteria. This is followed by the final dehydration and maturation of the endospore (Stages VI+VII). Bertil Halle, the lead scientist for this study, sums up the connection between partial dehydration, increased temperatures, and dormancy in Bacillus bacterial endospores by stating, What we have discovered is that the water in the spore is nearly as fluid as in regular bacteria, while the enzymes are largely immobile. Cooking may kill all microbes in food but won't get rid of any toxins they have already produced. In biology, a spore is a reproductive structure that is adapted for dispersion and surviving for extended periods of time in unfavorable conditions. Friedline AW, Zachariah MM, Johnson K, Thomas KJ 3rd, Middaugh AN, Garimella R, Powell DR, Vaishampayan PA, Rice CV. However, some bacterial spores will survive this and need temperatures around 130C to kill them. This can contribute to the spread of illness in humans. The new findings by Gheysens et al. Many living systems function best within specific temperature ranges. "Spring cleaning is a good time to check the temperature of your fridge," she added, "to make sure it's at the proper temperature to inhibit the growth of bacteria." (The U.S. Department .
