Paenibacillus durum (formaly Clostridium durum) was described by Smith and Cat as the dominant organism in a sediment core from the Black Sea. It digests it and produces NO2. Paenibacillus durum is important in established older gardens where there is a higher count of Protozoan and Nematodes. It fixes nitrogen from NH4 as part of [...]
Bacillus stearothermophilus is a thermophile and is widely distributed in soil, hot springs, ocean sediment, and is a cause of spoilage in food products. It will grow within a temperature range of 30-75 degrees Celsius. It appears in compost piles at the hot part of the cycle.
Bacillus thuringiensis Bacillus thuringiensis (or Bt) is a soil-dwelling bacterium, commonly used as a biological alternative to a pesticide; alternatively, the Cry toxin may be extracted and used as a pesticide. They are now used as specific insecticides under trade names such as Dipel and Thuricide. B. thuringiensis also occurs naturally in the gut of [...]
Bacillus pumilus strain GB34 is a naturally occurring bacterium that is especially common in soil and on dead plant tissue. When applied to soybean seeds, the bacterium protects the roots of the soybean plant against certain fungi. No harm to humans or the environment is expected from use of Bacillus pumilus strain GB34 as a [...]
Bacillus coagulans Bacillus coagulans is a lactic acid-forming bacterial species within the genus Bacillus. The organism was first isolated and described in 1932 and was elaborated in the fifth edition of Bergey’s Manual of Determinative Bacteriology. It’s purpose in soil is to secrete organic acids which dissolve phosphate into a soluble form and make it [...]
Streptomyces griseus Streptomyces griseus is a member bacterial species of the genus Streptomyces and are commonly found in soil. It is also called Actinomyces griseus. It produces Streptomycin, which is an antibiotic drug, the first of a class of drugs called aminoglycosides to be discovered, and was the first antibiotic remedy for tuberculosis. And it [...]
Saccharomyces cerevisiae is a species of budding yeast. It is perhaps the most useful yeast owing to its use since ancient times in baking and brewing. It is believed that it was originally isolated from the skins of grapes (one can see the yeast as a component of the thin white film on the skins of [...]
Bacillus megaterium Bacillus Megaterium is a Gram-positive, rod shaped Endospore-forming Bacteria. They are assumed to play a significant role in the biological cycles of carbon and nitrogen. It is considered Aerobic, but, it is also capable of growing under anaerobic conditions when necessary. One of the largest Eubacteria found in soil, and hence the name “mega” [...]
Azotobacter chroococum is one of many nitrogen fixing species of bacteria found in soils and plants. Their purpose is to take food from the plant through the roots, eat it, change it to a protein. Once the protean is released, nitrifying bacteria covert it to a Nitrate. Nitrate is fixed nitrogen. It is the same [...]
Bacillus polymyxa takes released (NH4) from Protozoan and Nematodes. It digests it and produces NO2. Bacillus polymyxa is important in established older gardens where there is a higher count of Protozoan and Nematodes. It fixes nitrogen from NH4 as part of the predator/prey nitrogen cycle.

Bacillus licheniformis B. licheniformis produces a variety of extracellular enzymes that are associated with the cycling of nutrients in nature. It is an apathogenic soil organism that is mostly associated with plant and plant materials in nature. Although it is most common to isolate this bacterium from is soil, it is believed that B. licheniformis [...]
Bacillus subtilus They allow for the control of plant pathogen infections. B. subtilis biofilm communities form a mutualistic interaction with plant rhizome systems. The plant benefits because B. subtilis provides preemptive colonization. Preemptive colonization prevents other pathogens from infecting the plant because B. subtilis has the advantage of being at the site first. The main [...]
In healthy soil there is more than 1,000,000,000 bacterium per cubic CM. Bacteria eats sugars excreted from plant roots and give back nitrogen. Bacteria is food for Protists (single cell organisms, sometimes with small tails, called flagella, and they are part of the nitrogen cycle for older, established landscapes). And Bacteria is food for [...]
