What is meant by axenic culture?
Definition. A microbial culture that contains only one species, variety, or strain of microorganism. Supplement. Microorganisms can be grown under controlled laboratory conditions in cultures where they are allowed to grow and reproduce.
What is axenic growth?
The growth and maintenance of a single species in isolation, free from foreign or contaminating species. Isolation in axenic culture is achieved usually by growing the species in an environment that was sterilized previously and was thereby rid of contaminating organisms.
What is non axenic?
All these technologies operate under non-axenic conditions, meaning the algae are growing together with other organisms like bacteria, yeasts, fungus and other algae species.
What do you mean by axenic medium?
axenic culture A culture medium in which only one type of microorganism is growing. Such cultures are widely used in microbiology to determine the basic growth requirements or degree of inhibition by antibiotics or other chemicals of a particular species.
Why is axenic culture important?
In biology, axenic describes the state of a culture in which only a single species, variety, or strain of organism is present and entirely free of all other contaminating organisms. Axenic culture is an important tool for the study of symbiotic and parasitic organisms in a controlled environment. …

What is the difference between an axenic and a pure culture?
As adjectives the difference between axenic and pure is that axenic is (biology) containing only a single species of microorganism for example, an “axenic culture” means that a pure sample of the organism in question has been grown while pure is free of flaws or imperfections; unsullied.

What are the two types of normal flora?
Although there are many different species of normal flora, these microbes typically fall into one of two categories: 1. resident microbes & 2. transient microbes. microbes.
What are the disadvantages of normal flora?
Sometimes normal flora can cause disease in the host body. If somehow the normal defense system or immune system of a host body is unable to restrict or tolerate the normal flora then they can cause diseases in the host body.

How are chemical agents used to obtain axenic cultures?
Antimicrobial and other chemical agents have been used in conjunction with physical methods for many years to obtain axenic cultures of planktonic organisms. This step was repeated several times to obtain an axenic culture.
