Which culture medium preparation is most commonly utilized in isolation of pure culture?
Solid media is used for the isolation of bacteria as pure culture. 'Agar' is most commonly used to prepare solid media.
What conditions might prevent a successful slide culture of a mold?
dry atmospherecold temperatureslack of a nutritive medium.
What is the selective property of the Snyder medium?
An Acidic pH
Why is direct selective or differential plating used for saureus testing rather than selective enrichment isolation?
Selective enrichment media are useful in recovering organisms which are in very low numbers, and they are often formulated like their corresponding isolation media.Selective enrichment will enhance their growth over competing bacteria,however undesired bacteria may grow.S.aureus grows poorly in the presence of others food microflora.By adding a selective agent to "poison" undesired organisms making the medium restrictive by including a nutrient only certain organisms can use or by leaving something out therefore direct selective or differential plating is more efficient to isolate s.aureus.Metabolically,it can utilize mannitol,which are not seen with other staphylococcal species.
When a substance is added to solid medium which inhibits growth of unwanted bacteria but permits the growth of wanted bacteria the medium is known as?
selective medium

What has the author Hassan Zehsazian written?
Hassan Zehsazian has written: 'An improved selective medium for the isolation of Verticillium dahliae Kleb' -- subject(s): Fungi in agriculture, Verticillium
Why is blood agar not useful a primary isolation medium?
Agar should be sterile and have limited nutrition for a primary isolation. Agar derived from blood would most likely encourage the growth of a wide variety of microorganisms, making it difficult to isolate the population you are interested in

Is Mannitol salt agar a selective or a differential medium?

What are selective media for aspergillus?
Peptone glucose agar (PGA) medium
What exactly is a Xanthomonas isolation Agar medium?
how xanthomonas oryzae can be cultured
What is L-15 cell culture medium?
It is just a type of a culture medium. The "L" there stands for Lebowitz, presumably the last name of the first person who came up with that culture medium.
Why is Sabouraud's dextrose agar a selective medium?
it only allows fungi to grow on the medium, and nothing else. so it selects for fungi.
