What is the action of Bacillus in concrete?

Bacteria of the Bacillus family have been employed in most studies dealing with bacterially assisted self-healing concrete due to their capacity to form calcium carbonate sediments using urea and calcium sources through the catalysis of urea hydrolysis into ammonium and carbonate to produce urease [[6], [7], [8]].

How is Bacillus subtilis used?

B. subtilis is often used as a probiotic preparation in the treatment or prevention of intestinal disorders. It is also used to produce antibiotics, as a fungicide, and in alternative medicine. This bacterium is part of the same family as Bacillus anthracis (anthrax).

What is Bacillus subtilis in?

Bacillus subtilis, known also as the hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium, found in soil and the gastrointestinal tract of ruminants, humans and marine sponges.

Why is Bacillus subtilis used in experiments?

Bacillus subtilis is actively used for both biochemical and genetic experiments because of its prototrophic nature and the availability of genetic systems. The spore stage of Bacillus subtilis provides a simple model system for studying the problems of cell differentiation.

What contains Bacillus subtilis?

subtilis is commonly found in pasteurised milk and dairy products [7]. Moreover, B. subtilis is also used for production of the fermented soybean food natto [8].

What is Bacillus pumilus used for?

Bacillus pumilus strain GB34 is used as an active ingredient in agricultural fungicides. Growth of the bacterium on plant roots prevents Rhizoctonia and Fusarium spores from germinating.

Which media is used for Bacillus subtilis?

The strain of Bacillus subtilis found on MacConkey agar and Chapman agar medium did not grow; however, it grow better on TSA agar medium containing 5\% fetal calf serum with circular ridges, smooth, moist, sticky and medium-sized colonies. LB agar and nutrient agar showed nearly circular, flat, dried colonies.

Why is Bacillus subtilis rod-shaped?

B. subtilis PBP2a, the product of pbpA, is involved in the formation of rod-shaped cells from oval spores during spore outgrowth (36) and is most similar to E. coli PBP2, which is required for maintenance of the rod shape of the cell (50).

What can Bacillus be used for?

Bacillus species are used in many medical, pharmaceutical, agricultural, and industrial processes that take advantage of their wide range of physiologic characteristics and their ability to produce a host of enzymes, antibiotics, and other metabolites.

What is the best source of Bacillus subtilis?

Best Forms of Bacillus subtilis Bacillus subtilis is readily found in soil, a testament to its ability to withstand environmental stressors.

Where is Bacillus Velezensis found?

Bacillus velezensis 83 was isolated from mango tree phyllosphere of orchards located in El Rosario, Sinaloa, México. The assessment of this strain as BCA (biological control agent), as well as PGPB (plant growth-promoting bacteria), were demonstrated through in vivo and in vitro assays.

Where does Bacillus pumilus come from?

B. pumilus, is a ubiquitous Gram-positive, aerobic, rod-shaped endospore-forming bacteria that can be isolated from a wide variety of soils, plants and environmental surfaces, and even from the interior of Sonoran desert basalt (Benardini et al., 2003).
