You have to make subculture from this slant and after incubation you can observe how many types of microorganisms are present in the nutrient agar slant. If you have one colony shape so you have a pure nutrient agar slant but if you have more than one type of colonies so the nutrient agar slant is contaminated.
Cell culture is a nearly universally used technique to grow material for biological testing. In cell culture, an original population of seed cells divide under tightly controlled conditions to propagate the culture. All of the daughter cells from the original population are clones.
Inoculum
Some examples of culture media used in microbiology experiments include nutrient agar, blood agar, MacConkey agar, and Sabouraud agar. These media provide the necessary nutrients for the growth of microorganisms in a controlled environment.
As culture density increases, toxin secretion by S. aureus is generally enhanced. This relationship may be influenced by factors such as nutrient availability and quorum sensing mechanisms. Additionally, high culture density can promote the expression of virulence factors, including toxins, in S. aureus.
Broth culture is a liquid growth medium used to grow microorganisms. It provides a nutrient-rich environment for the microorganisms to multiply. Broth culture can be easily sampled for further testing or analysis. It is commonly used in microbiology labs for cultivating and studying bacteria.
Kiev was strongly influenced by the culture of Russia. After the Mongols left in in ruins. Catherine the Great rebuilt the city in Russian style.
A mixed culture is a container that holds two or more identified and easily differentiated species of microorganisms. A contaminated culture was once pure or mixed (and thus a known entity) but since had contaminants (unwanted microbes of uncertain identity) introduced into it.

A normal culture may be contaminated by a mixture of microorganisms normally found on a person's skin (normal flora).

If a culture of salmonella is left open to the air it can become contaminated with other airborne bacteria.
