In response to variation of the environment:
- Most thermophilic bacteria have a small and threadlike shape. The threadlike shape has a greater surface-to-volume ratio, improving the speed of material transportation between
cells, and the rapid exchange of material with the surrounding environment is also of importance for organisms to develop at elevated temperatures.
- In mesophilic species, the influence of temperature on the size of the cell is varied among species. It was found that the size of Salmonella typhimurium decreases with increasing
incubation temperature. However, larger cells were observed in yeast, Bacillus, and E. coli at higher incubation temperatures.
