Proteus vulgaris It is grouped with the enterobacteriacea and is an opportunistic pathogen of humans. In humans P.vulgaris is known to cause urinary tract infections and wound infections. P.vulgaris is associated with nosocomial infection, and has the ability to degrade urea to ammonia by production of the enzyme urease.McConkey agar contains lactose, which P.vulgaris does not ferment. It ferments glucose, sucrose, galactose, glycerol occasionally maltose with gas production, but never lactose.P.vulgaris ferments liquefies gelatin, casein, and blood serum, curdling milk with acid production.n humans P.vulgaris is known to cause urinary tract infections and wound infections.

YEAST AND FERMENTATION LAB In beer brewing, germinating barley is added to the fermenting wheat. The germinating barley supplies the enzyme diastase which breaks the starch into maltose, a disaccharide of glucose. The yeast can separate maltose into glucose, but the metabolism of maltose by yeast is a slow process. As the maltose is hydrolized into two glucose molecules, the glucose is then fermented into ethanol.

Enteric fermentation Over 200 species of microorganisms are present in the rumen, although only about 10% of these play an important role in digestion. Most of the CH 4 byproduct is belched by the animal, however, a small percentage of CH 4 is also produced in the large intestine and passed out as flatulence.rom Wikipedia, the free encyclopedia. Enteric fermentation is a digestive process by which carbohydrates are broken down by microorganisms into simple molecules for absorption into the bloodstream of an animal.

- Some bacteria can grow in the nutrient medium but cannot ferment the sugar, while other bacteria can ferment the sugar, producing nonacidic and/or gaseous end products. In both cases, the medium will remain alkaline, or red.Some of the nonacidic end products of fermentation are acetone, butanol, and ethanol.acillus subtilis can ferment more than one type of sugar, such as sucrose and dextrose, but cannot ferment other types of sugars, such as lactose. B. subtilis is a gram-positive rod often found in soil and decomposing organic matter; it is a common laboratory contaminate.

Escherichia Glucose and lactose are fermented with the production of acid and gas. These organisms are found in feces; some are pathogenic to humans, causing enteritis, peritonitis, cystitis, and other disorders. It is the type genus of the family Enterobacteriaceae. The type species is Escherichia coli. [T.

Flatulence The process of fermentation produces gas as a by-product. Some of the gas is absorbed into the bloodstream and breathed out by the lungs. The remainder is pushed along the bowel. High fibre foods – fibre is essential to the health of the digestive system, but it can create excessive gas.

- A number of microorganisms utilize the phosphoketolase pathway as the majorroute of glucose metabolism. Leuconostoc mesenteroides, a typical heterofermenta-tive organism, utilizes this pathway, yielding lactate, ethanol, and carbon dioxideas shown in Figure 8-3.

- Proteus vulgaris Growing on EMB Agar. Only gram-negative bacteria grow on EMB agar. Gram-positive bacteria are inhibited by the dyes eosin and methylene blue added to the agar. Because Proteus vulgaris does not ferment lactose or produce acid, their colonies appear grey on EMB agar.Photograph from MicrobeLibrary.org Courtesy of Naowarat Cheeptham and Carolynne Fardy, Thompson Rivers University.ram-positive bacteria are inhibited by the dyes eosin and methylene blue added to the agar.

Lactobacillus fermentum Lactobacillus fermentum. Survives well in the complex and harsh environment of the animal and human stomach and intestinal tract. Produces lysozyme, gas from glucose and NH3 from arginine. It is the major heterofermentative Lactobacillus species of the human gut. Also found in fermenting plant and animal materials.

Trapped Gas Undigested lactose can include symptoms such as diarrhea, abdominal pain, and flatulence. Fructose containing foods such as dried fruits, honey, sucrose, onions, artichokes and corn syrup can cause bloating. Celiac disease is believed to cause bloating and increased gas formation in the digestive system.

- in the gastric mucosa. The low pH (~2) of the gastric juice aids protein digestion in a couple of ways. First, the low pH denatures the tertiary structures of ingested protein, making them easier to digest enzymatically. Secondly, the low pH is required for the activation of pepsin. Pepsin is produced by chief cells of the gastric mucosa in an inactive (zymogenic) form called pepsinogen. Pepsinogen is inactive when released in the gastric pits, but once it diffuses into the lumen of the stomach the acidic conditions enable it to have a weak proteolytic activity (Fig 11.3). Pepsinogen can digest some Enzyme Activity pH

This site is no longer maintained and has been left for archival purposes Proteus vulgaris. The genus Proteus is classified in the enteric bacteria, together with Escherichia coli, Salmonella, Shigella, Enterobacter and Serratia. All these bacteria are small, Gram-negative rods and are facultative anaerobes: they ferment sugars in anaerobic conditions but can use a wide range of organic molecules in aerobic conditions.

Proteus vulgaris Proteus vulgaris is a rod-shaped Gram-negative chemoheterotroph bacterium. The size of individual cells varies from 0.4~0.6μm by 1.2~2.5μm. P. vulgaris possesses peritrichous flagella, making it actively motile. It inhabits the soil, polluted water, raw meat, gastrointestinal tracts of animals, and dust.

Yogurt In the process of using the lactose sugar from the milk, Lactobacillus produces acid which makes the yogurt sour and a less suitable place for other microbes. This is why there is a dramatic decrease in the amount of microbes that live in the yogurt niche when compared to the milk niche.

Natural relief from digestive gas Carbohydrates, which contain natural sugars, cause gas, whereas proteins and fats typically do not. Beans, for example, are legendary for producing gas, because they contain the indigestible sugars stachyose, verbascose and raffinose. These sugars ferment contents in the digestive tract, producing gas and lots of it.

Proteus mirabilis Proteus mirabilis appears as Gram-negative rods after Gram staining under bright-field microscopy with 1000 times magnification. Proteus mirabilis is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. It shows swarming motility and urease activity.P. mirabilis causes 90% of all Proteus infections in humans. It is widely distributed in soil and water.iagnosis [edit]. An alkaline urine sample is a possible sign of P. mirabilis. It can be diagnosed in the lab due to characteristic swarming motility, and inability to metabolize lactose (on a MacConkey agar plate, for example). Also P. mirabilis produces a very distinct fishy odor.
