Question

Axenic culture means

• A. Study of characteristics of a culture, in an environment of other living organisms
• B. Study of characteristics of a culture, in an environment free of other living organisms
• C. Study of characteristics of a culture, of living organisms without environment effect
• D. Study of characteristics of a culture, in absence of nutrients

Hint:

• Axenic culture = Pure culture.
• Contains only one known species, strain, or type of microorganism.
• Free from contamination by any other living organisms.
• Essential for studying the properties of a specific microorganism.

Answer 1

The Correct Option is B

An axenic culture refers to a culture that is completely free of other living organisms except the one being studied. This ensures that the characteristics of a specific organism can be observed without the influence or interference of other biological entities. In biotechnology, maintaining an axenic environment is crucial for studying the intrinsic properties of microorganisms or cells, allowing researchers to obtain accurate and uncontaminated results.

Option	Explanation
Study of characteristics of a culture, in an environment of other living organisms	Incorrect - Involves presence of other organisms, not axenic.
Study of characteristics of a culture, in an environment free of other living organisms	Correct - This defines an axenic culture.
Study of characteristics of a culture, of living organisms without environment effect	Incorrect - Environment effects are not the focus of axenic studies.
Study of characteristics of a culture, in absence of nutrients	Incorrect - Axenic culture is not defined by nutrient presence.

Therefore, the correct option is: Study of characteristics of a culture, in an environment free of other living organisms.
