Will Alcaligenes faecalis grow on MacConkey agar?
No, Alcaligenes faecalis will not grow on MacConkey agar. MacConkey agar is selective for gram-negative bacteria that ferment lactose. Alcaligenes faecalis is a gram-negative bacteria that does not ferment lactose, so it will not grow on MacConkey agar.
What is the pH for Alcaligenes faecalis?
The pH range for optimal growth of Alcaligenes faecalis is around 6.0 to 8.0. This bacterium is capable of growing in a slightly acidic to neutral pH environment.
What are Alcaligenes faecalis characteristics?
Alcaligenes faecalis is a motile, obligate aerobic and motile bacteria. The colony morphology of alcligenes faecalis is that of small colonies, grey in color, with rough borders and spreading edges. These bacteria are rod-shaped, and colonies are thin, and often have a â??fruityâ?? odor that many people associate with green apples.
Can alcaligenes faecalis grow on emb?
I dont believe so. I think I have AF for my unknown since I got all negative tests mostly and I didn't get growth on EMB.
Are all aerobic bacteria oxidase positive?
yes, all aerobic cells are oxidase positive. The oxidase test is testing for the presence of cytochrome oxidase [by reducing it with an artificial substrate which turns purple when oxidised]. In aerobic cells cytochrome oxidase's normal role is in the electron transport chain, passing electrons from cytochrome c to oxygen. hence if the cell is aerobic then oxygen is terminal electron acceptor in the cells ETC and thus it will give a positive result in the oxidase test.
Is alcaligenes faecalis positive or negative for urea?
Usually positive, but some strains may not.
Is the bacteria Alcaligenes faecalis pathogenic?
no
Can Alcaligenes faecalis produce endo-spores?
No, Alcaligenes faecalis cannot produce endospores. It is a Gram-negative bacterium that does not possess the capability to form endospores.
What Two genera that are oxidase positive?
Neisseria, Alcaligenes, Moraxella, and Pseudomonadaceae are genera of oxidase positive microorganisms.
Will Alcaligenes faecalis grow on MacConkey agar?
No, Alcaligenes faecalis will not grow on MacConkey agar. MacConkey agar is selective for gram-negative bacteria that ferment lactose. Alcaligenes faecalis is a gram-negative bacteria that does not ferment lactose, so it will not grow on MacConkey agar.
Can Alcaligenes faecalis produce endo spores?
yes
What diseases are caused by alcaligenes faecalis?
There are several different diseases and conditions that are caused by Alcaligenes Faecalis. Some of these conditions and diseases include endophthlamitis and many different types of infections.
What is the pH for Alcaligenes faecalis?
The pH range for optimal growth of Alcaligenes faecalis is around 6.0 to 8.0. This bacterium is capable of growing in a slightly acidic to neutral pH environment.

How do you tell the difference between S epidermidis and E faecalis?
Metabolic tests such as an oxidase test can be used to differentiate S epidermidis and E faecalis. Such a test can be conducted by adding H2O2 to the colony. The result for S aureus will be negative and the result for S epidermidis will be positive.
What are the results for a capsule stain for alcaligenes faecalis?
I dont have any answer, But i will post it when i will know . No change in color or reaction on Indole Test - Negative result on Indole Test.
