Solution

Amswer:-Psychrophile bacteria are extremophiles that can tolerate low temperature. Thus these bacteria can grow and reproduce at very low temperature ranging from-25 to +5 degree Celsius.

Halophile:- These bacteria can grow at high salt concentration habitats.

Antagonist effect or antagonism :- Where two or more agents have effect in combination that is less than the individual effect.

Synergistic effect:- it is the opposite of antagonism where the two or more agents have greater effect in combination than separate individual effect.

Symbiotic effect :- Relationship between two dissimilar organisms that is beneficial for both.

Lyophilization:- Technique by which water is removed from frozen material by plaxing it in vacuum.
