As cells start growing in the log phase, there’s also an increase in the accumulation of waste products. Since the system is closed, and no extra nutrients are being added from outside, the available nutrients are exhausted. Temperature is another important factor for bacterial growth. Bacteria that grow best in cooler environments are called psycrophiles. These microbes prefer temperatures ranging between 4°C and 25°C (39°F and 77°F). Extreme psycrophiles thrive in temperatures below 0°C/32°F and can be found … Meer weergeven In nature, bacteria do not experience perfect environmental conditions for growth. As such, the species that populate an environment change over time. In a laboratory, however, optimal conditions can be met by … Meer weergeven Bacteria, like all living organisms, require an environment that is suitable for growth.
