P. vulgaris is H2S positive because it obtains its energy by oxidizing organic compounds or molecular hydrogen H2 while reducing sulfates to sulfides,especially to hydrogen sulfide.[1] In a sense, they "breathe" sulfate rather than oxygen. Sulfate-reducing bacteria can be traced back to 3 billion years ago and are considered to be among the oldest forms of bacteria.Many bacteria reduce small amounts of sulfates in order to synthesize sulfur-containing cell components; this is known as assimilatory sulfate reduction. By contrast, the sulfate-reducing bacteria reduce sulfate in large amounts to obtain energy and expel the resulting sulfides as waste; this is known as dissimilatory sulfate reduction. They are anaerobes which use sulfate as the terminal electron acceptor of their electron transport chain.Most sulfate-reducing bacteria can also reduce other oxidized inorganic sulfur compounds, such as sulfite, thiosulfate, or elemental sulfur (see sulfur-reducing bacteria

What is the complete name of the test of a hypothesis?
The complete name of the test of a hypothesis is the "hypothesis testing procedure." This procedure involves formulating a null hypothesis and an alternative hypothesis, then using statistical methods to determine whether there is enough evidence to reject the null hypothesis in favor of the alternative. It typically includes steps like selecting a significance level, calculating a test statistic, and comparing it to a critical value or using a p-value to draw conclusions.
Is p Allen smith as nice as he seems?
P. Allen Smith is widely regarded as a warm and friendly personality in the gardening and lifestyle community. His public persona, characterized by enthusiasm and knowledge, suggests he is genuinely passionate about his work. However, personal experiences with individuals may vary, and opinions on his niceness can differ based on interactions. Overall, his reputation in the media tends to emphasize his positive traits.
How can you differentiate between proteus mirabilis and proteus vulgarisi?
Proteus mirabilis and Proteus vulgaris can be differentiated based on their biochemical characteristics. One key distinction is that P. mirabilis is typically urease-positive and does not produce indole, while P. vulgaris is urease-positive and does produce indole. Additionally, P. vulgaris can be further differentiated from P. mirabilis by its motility and the ability to ferment certain carbohydrates. Laboratory tests, such as the urease test and indole test, can help confirm the identification of each species.
What test will show you the difference between Proteus vulgaris and Morganella morganii?
alpha-glucosidase test: using 5-bromo-4-chloro-3-indolyl-alpha-D-glucopyranoside (included in chromogenic media), but not using alpha-methyl-glucoside fermentation. Cronobacter (E. sakazakii) are positive for this test and E. aerogenes are negative.

What test will differentiate between Proteus vulgaris and Pseudomonas aeruginosa?
This is a bit tricky. Both Proteus vulgaris and Pseudomonas aeruginosa are Gram-negative and rod-shaped. According to Bergey's Manual of Systematic Bacteriology, Proteus vulgaris tests positive for sulfur reduction, urease production, tryptophan deaminase production, and indole production. Pseudomonas aeruginosa reduces sulfur and nitrate, and has a characteristic green color. The API 20E Identification System is a test strip that can be used to identify Proteus vulgaris versus other bacteria.An even easier way to test this is the gelatinase test.Or, slant the bacteria on a Triple Sugar Iron slant or place them in a SIM agar deep. P. vulgaris tests positive for Hydrogen Sulfide production, changing the media to a black color around the organism, while P. aeruginosa does not produce Hydrogen Sulfide.
Is proteus vulgaris arabinose negative?
No. The arabinose medium should stay red if incubated with P. aeruginosa, not turn yellow indicating arabinose positive.
Can you test positive for p c p from second hand smoke?
yes
Does Proteus vulgaris have a capsule?
Yes, Proteus vulgaris can have a capsule, which is a protective layer outside the cell wall. The presence of a capsule in P. vulgaris can contribute to its virulence and ability to evade the host's immune system.
Is P vulgaris a lactose fermenter?
Yes, P. vulgaris is a lactose non-fermenter. It does not possess the enzyme beta-galactosidase needed to ferment lactose into glucose and galactose. Instead, it typically ferments sugars like glucose and sucrose.
What does a positive presence-absence test indicate?
The Presence-Absence (P-A) test is a presumptive detection for coliforms.
Does proteus mirabilis ferment lactose?
No.----------------------------------------------------------Disagree. You'll find a positive sucrose fermentation test for P. vulgaris at MicrobeLibrary.org. The site is an affiliate of the American Society of Microbiology, so I'm guessing it's a safe bet.
What is the probability of testing positive for the disease?
The probability isP(you have the disease)*P(the test shows positive when testing someone with the disease) +P(you don't have the disease)*P(the test shows positive when testing someone without the disease).The second category is particularly important if the disease is rare but the probability of a type II error is large.
