Does Enterobacter aerogenes produce gas in the Kligler Iron Agar test?
Yes. Enterobacter aerogenes ferments lactose and glucose as well as producing gas. It does not produce H2S. Occasionally the slant may revert to an alkaline reaction even though lactose has been fermented. Another lactose test should be formed, such as the reaction on MacConkey agar
What is the gram stain of enterobacter aerogenes?
Enterobacter aerogenes is a Gram negative rod-shaped bacterium in the same family as Esherichia coli. It can grow on many of the same selective media as Esherichia coli, including: MacConkey Agar, EMB agar and Lauryl-Tryptose broth. E. aerogenes ferments lactose, producing acid and gas like Esherichia coli and is classified as an example of coliform bacteria. There are several significant differrences between E. aerogenes and E. coli: 1) Most strains of E.coli are able to grow and produce acid from lactose in a medium such as lauryl tryptose broth or brilliant green bile broth at 44.5 degrees C. while most strains of E. aerogenes do not grow well at that temperature, E. aerogenes grows better at temperatures betwee 34 - 40 degrees C. 2) E. aerogenes carries out 2,3-butanediol fermentation and thus give a positive test in the Voges-Proskauer test while E. coli is negative. 3) E. coli is positive in the methyl red test while E. aerogenes is usually, but not always, negative (this is not the best test to rely on). 4) E.coli is positive for the indole test while E. aerogenes is negative, this is a very reliable test. 5) E. aerogenes can grow on Simmon's citrate agar while E. coli does not. You can distinguish between E. aerogenes and bacteria in the Proteus and Salmonella genera by using the hydrogen sulfide test, using either Kligler's iron agar or triple sugar iron agar. Most Proteus and Salmonella strains produce hydrogen sulfide and make a black precipitate but E. aerogenes does not. There are a lot of similarities between Enterobacter aerogenes and Klebsiella pneumonia. The urease test is one of the few tests that distinguishes E. aerogenes from K. pneumonia.

Bacteria that produce colonies containing a red pigment were distributed on nutrient agar and exposed to ultraviolet light for several days the colonies that developed were red with the exception of?
Mutation
The correct microbiological term for the tiny sample of specimen that is put into a nutrient medium in order to produce a culture is the?
Inoculum
Which bacteria forms pink colonies in nutrient agar plates?
Nutrient agar is a general purpose medium supporting growth of a wide range of non-fastidious organisms. Most any bacteria will grow on it.An example of a fastidious organism is Neisseria gonorrhea, which requires blood or hemoglobin and several amino acids and vitamins in order to grow.
What carbohydrates can Enterobacter aerogenes ferment?
90% to 100% of Enterobacter aerogenes strains can ferment glucose, sucrose, and lactose. The same percentage of strains produce gas as a byproduct of that fermentation.

What is the history of E.aerogenes?
Enterobacter Aerogenes is an aerobic, Gram-negative, rod-shaped bacteria that can live in the human gastrointestinal tract without causing illness, can cause skin infections, can live in soil, and has been known to produce opportunistic infections in hospital settings, especially around catheters, etc.

What are the example of selective media?
Examples of selective media include MacConkey agar, Eosin methylene blue agar, and Mannitol salt agar. These types of media contain ingredients that selectively inhibit the growth of certain organisms while allowing the growth of others.
What did the middle colonies produce?
they produced food.
What nutrient is found in milk and cereals and sunlight helps produce it in the body?
vitamin D
Agrobacterium?
produce plant tumors to gain nutrient -> These tumors are often fatal to plant
Does anorexia cause flaky toenails?
yes, because of the nutrient you need to produce the nails is lacking.
