42. If an organism is a psychrophile, what effect would the following temperatures have on its growth? a. 1000C b. 370C C. 40C

Solution

a. at 100^oC they are thermophile, they can function at high temperatures. They are the form of extremophile.

b. Three strains of psychrophiles were facultative having an optimum temperature for growth at about 25-28 degrees C and they show maximum growth at about 32-37 degrees C.

c. Lipase is produced from Moraxella, amylaseisproduce fromAlteromonas haloplanctis, and lactamase is produced fromPsychrobacter immobilis and protease from Bacillus is maximal at temperatures close to that of their environment (—2 to 4 C).
