Classify the microorganisms on the basis of their response to temperature
Answers
Generally,an increase in temperature will increase enzyme activity. But if temperatures get too high, enzyme activity will diminish and the protein (the enzyme) will denature. ... Every bacterial species has specific growth temperature requirements which is largely determined by the temperature requirements of its enzymes.
Answer:
Explanation:
he basic means of measuring growth requires bacterial enumeration (cell counting).
Methods for bacterial cell counting include: 1. direct and individual (microscopic, flow cytometry), 2. direct and bulk (biomass), 3. indirect and individual (colony counting), or 4. indirect and bulk (most probable number, turbidity, nutrient uptake).
A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold. All human pathogens are mesophiles.
Cold shock proteins help the cell to survive in temperatures lower than optimum growth temperature.
Heat shock proteins help the cell to survive in temperatures greater than the optimum, possibly by condensation of the chromosome and organization of the prokaryotic nucleoid.
mesophile: An organism, especially a microorganism, that lives and thrives at moderate temperatures.
psychrophile: An organism that can live and thrive at temperatures much lower than normal; a form of extremophile.
thermophile: An organism that lives and thrives at relatively high temperatures; a form of extremophile; many are members of the Archaea.
