Bacillus megaterium Bacillus megaterium. Bacillus megaterium is a rod-like, Gram-positive, mainly aerobic spore forming bacterium found in widely diverse habitats. With a cell length of up to 4 µm and a diameter of 1.5 µm, B. megaterium is amongst the biggest known bacteria. The cells often occur in pairs and chains, where the cells are joined together by polysaccharides on the cell walls.

Bacillus subtilis A member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough, protective endospore, allowing it to tolerate extreme environmental conditions.B. subtilis has historically been classified as an obligate aerobe, though evidence exists that it is a facultative aerobe.his species is commonly found in the upper layers of the soil, and evidence exists that B. subtilis is a normal gut commensal in humans. A 2009 study compared the density of spores found in soil (about 10 6 spores per gram) to that found in human feces (about 10 4 spores per gram).

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.ith basic microbiological technique, samples believed to contain Proteus are first incubated on nutrient agar to form colonies. To test the Gram-negative and oxidase-negative characteristics of Enterobacteriaceae, Gram stains and oxidase tests are performed. Candidae organisms are Gram and oxidase negative.

SAARS: Gram positive rods (GPR) (microbiology) Bacillus spp. After coagulase-negative staphylococci and diphtheroids, members of the genus Bacillus are the third most common skin contaminant found in clinical specimens. On Gram stain they are large, wide, Gram-positive rods, often occurring singly or in pairs, which can produce endospores.

Lactobacillales (April 2015). Lactobacillales or lactic acid bacteria (LAB) are a clade of Gram-positive, low-GC, acid-tolerant, generally nonsporulating, nonrespiring, either rod-or cocci-shaped bacteria that share common metabolic and physiological characteristics.his aspect helps LAB to outcompete other bacteria in a natural fermentation, as they can withstand the increased acidity from organic acid production (e.g., lactic acid). Laboratory media used for LAB typically include a carbohydrate source, as most species are incapable of respiration. LAB are catalase negative.

- Bacillus megaterium is a gram positive, spore producing bacteria. It is a Eubacteria and is found in the soil. It has a rod shape and is one of the largest Eubacteria.Colonies form in chains due to sticky polysaccharides on the cell wall. It is very important in the biotech industry due to its size and its' enzyme and cloning abilities.t also is very efficient in cloning due to no protease degradation of product and good stability of recombinant plasmids.

- Proteus vulgaris is a rod-shaped, nitrate-reducing, indole+ and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals.ver the past two decades, the genus Proteus, and in particular P. vulgaris, has undergone a number of major taxonomic revisions. In 1982, P. vulgaris was separated into three biogroups on the basis of indole production.

- The capsule is not synthesized by the closest relatives of B. anthracis, i.e., B. cereus and B. thuringiensis, and this criterion can be used to distinguish the species. Cell Walls The variability of cell wall structure that is common in many Gram-positive bacteria does not occur in the genus Bacillus.tructure of the muropeptide subunit of the peptidoglycan of Bacillus megaterium. In most Bacillus species, an interpeptide bridge that connects D-alanine to meso-diaminopimelic acid (DAP) is absent. In addition, all Bacillus spores contain this type of muramic acid subunit in the spore cortex.

Culturelle Lactobacillus GG Lactobacillus GG (LGG) has shown promising results in treating diarrhea caused by viruses and bacteria in both adults and children. Measurements of intestinal microflora show that LGG adheres to the intestinal wall during healthy periods as well as during episodes of diarrhea.actobacillus GG not only lowered levels of glycosylated hemoglobin, it also improved glucose tolerance in the animals. Probiotics such as Lactobacillus GG, Bifidobacterium, and Lactobacillus acidophilus significantly reduce the amount of pathogenic bacteria that inhabit the nasal passages, according to a recent study.

Does saltpeter suppress male ardor? Dear Cecil: As a lad I went to the same repressive boarding school that made George Bush what he is today. As a student I believed, as did we all, that the school authorities were mixing potassium nitrate, or saltpeter, into our food to control our sexual appetites.

Lactobacillus acidophilus Lactobacillus acidophilus (New Latin 'acid-loving milk-bacillus') is a species of gram positive bacteria in the genus Lactobacillus. L. acidophilus is a homofermentative, microaerophilic species, fermenting sugars into lactic acid, and grows readily at rather low pH values (below pH 5.0) and has an optimum growth temperature of around 37 °C (99 °F).
