How do you know that you have used aseptic technique correctly and have achieved a pure culture?
When the aseptic transfer of bacteria is done, the organism should produce a red pigment, when it is incubated under the appropriate conditions. If the person conducting the experiment notices a red or pink color, it can be assumed that the transfer was a success.
Do microorganisms affect soil?
Nitrite formation by rhizoplane microorganisms of rice seedlings was examined in comparison with that by nonrhizosphere paddy soil microorganisms. Effect of nitrite on root growth of rice seedlings was also investigated under aseptic water culture condition. Rhizoplane microorganisms accumulated much nitrite than the other microorganisms in a root extract medium. The accumulated nitrite maintained a stationary level for more than 2 days. In glucose enriched media, both group of microorganisms accumulated nitrite only temporarily. Formation of lateral roots and root hairs was stimulated in the solution containing 1.12-11.2 ppm NO_2^--N but elongation of primary roots was depressed under 5.6-11.2ppm NO_2^--N concentrations. Growth of rice seedlings was inhibited at concentrations higher than 5.6 ppm. Comparative studies indicated that effect of soil microorganisms on root morphology would have been caused by nitrite produced by rhizoplane microorganisms. Additional Index Words : nitrite formation, rhizoplane microorganisms, rice root, aseptic culture.
What microorganisms required special culture procedures?
microorganisms that.require special culture procedures. Mycobacterium tuberculosis. Mycoplasma pneumonia. Bordetella pertussis. Legionella pneumophila. Chlamydia pneumoniae. Chlamydia psittaci. Pneumocystis carinii
Name some of the microorganisms that are difficult to culture under laboratory conditions?
salmonella is one.
Why does filtered RPMI culture medium still contaminated after 4 days although the container is not opened?
Check your aseptic technique, thoroughly ethanol the outside of the bottle, especially the cap and neck. Verify the receiving container is sterile or autoclaved. Do not reuse filters. Otherwise, using a 0.22nm filter should eliminate any contamination.

Why media culture is specifically?
Culture media should be specific to avoid contamination of unwanted microorganisms and to obtain a pure culture of microorganisms.

Why is aseptic technique necessary for successful cultivation of pure cultures in the laboratory?
Short answer is Koch's postulates. Long answer you can't ascribe any scientific data you may gather to a bunch of bacteria on a plate or in a culture, as you won't know which of the bacteria gave you the result you observed. So if you are trying to figure out which bacteria causes a disease, inoculating a mix of bacteria won't tell you which one causes the disease. Isolating each one using aseptic technique and then inoculating individually and finding the disease in one animal will tell you which bacteria caused to disease.
Why is aseptic techniques so critical?
aseptic technique is the procedure in which work is done in microbial free environment and is necessary for the prevention of infections to the human beings e.g. doctor or patient or other hospital workers and to the microbiologist it is also done for preventing the contamination in microbial culture grown in laboratory
What is an auxanogram?
An auxanogram is a culture of microorganisms used in auxanography - the study of the effects of changes of environment in the growth of microorganisms.
Describe the aseptic technique that would be used when flooding the agar plate with bacteria?
An agar plate was flooded with a culture of a species of bacterium usually found in the mouth. Four steriled paper discs, A, B, C, and D, each containing a different brand of mouthwash, were then placed on the agar plate. The drawing shows the appearance of the plate after it had been incubated below body temperature for three days, this is to ensure that the bacteria are not harmful to humans.

What makes the results of a skin culture normal?
Many types of microorganisms are normally found on a person's skin. Presence of these microorganisms is noted on a skin culture report as "normal flora."
What culture media is used to support growth of microorganisms?
Agar
What is a culture media used to support growth of microorganisms?

What does a culture medium provide to a living thing?
Culture media in microbiology is a media where microorganisms like bacteria from a sample is grown into colony for the identification of particular organism.eg-simple media like blood agar,choclate agar
