Temperature range for psychrophiles
WebPsychrophiles grow best in the temperature range of 015 C whereas psychrotrophs thrive between 4C and 25 C. Mesophiles grow best at moderate temperatures in the range of 20 C to about 45 C. Pathogens are usually mesophiles. Thermophiles and hyperthemophiles are adapted to life at temperatures above 50 C. What does the term Thermophile mean? WebGrowth of five strains of psychrophilic bacteria (four Arthrobacter and one Pseudomonas) isolated from glacial deposits was studied at different temperatures. Three strains were facultative psychrophiles, having an optimum temperature for growth at about 25-28 degrees C and a maximum at about 32-34 degrees C.
