What are the TSI test results for klebsiella?
A/a with gas
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
Does bacillus megaterium ferment glucose?
Yes, acid is produced but gas is not.
What is the difference between a coliform an enteric and enterococci?
Enterics are gram- facultatively anaerobic rods; Coliforms are enterics that produce acid and gas from lactose; Enterococci are catalase-, gram+ cocci belonging to Lancefield Grp D found in GI tract
Is bacillus cereus positive for methyl red?
Most bacteria in Tribe V are able to utilize Citrate, with the exception of Hafnia and Pantoea (+/-). The 2 most common Klebsiella (oxytoca and pneumoniae), can utilize citrate, so should be citrate positive.
What type of bacteria is typhoid causing bacteria?
The are gram negative bacillus shaped bacteria. They are facultative anaerobic bacteria. They ferment the glucose to produce acid and gas. They ferment the sulfur containing amino acids to produce H2S gas. They do not ferment the lactose.
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.

Does micrococcus roseus test positive for mixed acid fermentation?
Micrococcus roseus ferments sucrose, but no gas. Does not ferment lactose, glucose, or mannitol. Beta hemolitic. Catalase positive. Pink colonies of groth
Can you develop lactose intolerance?
Yes. Lactose intolerance is a phenomena of the digestive system. Just because you have milk in the mammeries has no bearing on what happens to milk in the intestines. The same argument goes for lactose intolerant (human) mothers.
What are the symptoms of lactose intolerance?
intestinal gas and bloating after dairy products are consumed
What causes the holes in Swiss cheese?
As the cheese ferment the bacteria consumes the sugar and produce gas wich in turn creates small bubbles in the cheese.
Does lactose intolerance cause bad breath?
no. as usually if not caused by gum disease, bad breath is caused by a gas from the stomach. someone who is lactose intolerant would have bad breath if consuming dairy produce as it would cause a stomach upset
Does bacillus megaterium ferment glucose?
Yes, acid is produced but gas is not.
Do dairy products cause constipation?
When a person is lactose intolerant, any milk that is not lactose free will cause that person to have gas.? Lactose intolerance means a person does not have enough production of lactase enzyme.? When lactose is not broken down, it passes into the intestine where bacteria in the gut digest it and release gas.
Why are you farting alot?
Farting happens because bacteria in the digestive tract produce hydrogen or methane gas as a waste product of their own metabolism. Different foods have different effects on these bacteria. Beans notoriously produce gas because they include a kind of carbohydrate that human beings don't digest, which therefore becomes a rich source of food for bacteria. Onions often stimulate bacterial gas production as well. For people who are lactose intolerant, lactose (also known as milk sugar) creates a huge amount of gas because the lactose intolerant person cannot digest it (due to a lack of the lactase enzyme) and therefore the bacteria do. If you have problems after drinking milk or eating other dairy products, you are probably lactose intolerant.
