Microaerophiles are microorganisms which are unable to grow when oxygen concentrations reach those found in air (20%) but nevertheless whose growth requires the presence of some oxygen (e.g., 2 to 10%). "Microaerophiles appear to grow best in the presence of a small amount of free oxygen. They grow below the surface of the medium in a culture tube at the level where oxygen availability matches their needs

Which type of organism aerobe anaerobe microaerophile facultative anaerobe would most likely be affected negatively by the use of old media?
I would think an aerobic organism would do the worst in an oxygen poor media, which would be one of the results of having an older media sitting around.
What is the difference between a faculatative anaerobe and a microaerophile?
A faculatative anerobe does NOT require oxygen for growth but may use if available so it can grow in aerobic and anaerobic conditions. Too much oxygen is NOT toxic. A micro-aerofile CAN'T grow without oxygen but too much oxygen is toxic so it must have a low concentration in order to grow.
How microbes are classified based on their oxygen preferences?
On the basis of oxygen requirement microorganisms are classified asAerobes: organisms that use molecular oxygen as electron acceptor.Anaerobes: organisms that use some molecule other than molecular oxygen as electron acceptor.Facultative organisms : organisms that can use either molecular oxygen or some other chemical compound as electron acceptor.
Use of agar slant?
An agar slant is when a test tube is filled with liquid agar and allowed to cool and harden at an angle (slant). Agar is mixed with other nutrients to provide a medium for which bacteria can grow on.
What would you call a microaerophile that needs an elevated carbon dioxide level?
Capnophile.
Is plasmodium falciparum aerobic or anaerobic?
It is an obligate microaerophile. Meaning it lives best in small amounts of oxygen.
