Our Microbes and Fungi

Our blend of microbial & fungal life is what sets us apart, so we figured we’d share what makes us special.

Nitrogen Fixing Bacteria

Azotobacter chroococcum – This bacterial species creates an enzyme, Nitrogenase, which reduces nitrogen (N2) to ammonia (NH3). (1) This provides Nitrogen for the plant. To top it off, this doesn’t cause any damage to our waterways via excess nitrates as Nitrogen fertilizers can.

Azotobacter vinelandii – This bacterial species also creates the enzyme, Nitrogenase, which reduces nitrogen (N2) to ammonia (NH3). Provides the same benefits as above, but adds to the diversity and nitrogen provided.

Azospirillum brasilense – Out of the species discussed, this is probably the most well known. As with the previous strains, creates the enzymes Nitrogenase for nitrogen fixing. In addition it creates a number of growth promoting hormones. (2)

Azospirillum lipoferum – This bacterial species is mostly known for its use fixing nitrogen for legumes, however, among other plants it can also increases the number of lateral roots and root hairs. This enlarges the root surface available for nutrients, resulting in a higher nutrient uptake by inoculated roots and an improved water absorption of the plant. (3)

Bradyrhizobium japonicum – This is a nitrogen fixing microbial species that associates with Legumes.

Solubilizing Bacteria

Bacillus megaterium – This strain can produces organic acids that naturally chelate phosphorus into a plant soluble state with calcium. It also protect against Fusarium wilt, a common pathogen for plants. (4) It creates proteins, and enzymes that are beneficial to plants.(5) It even does it part with bioremediation. (6)

(5) – Bacillus megaterium–from simple soil bacterium to industrial protein production host

Bacillus polymyxa (Paenibacillus) – This plant growth promoting rhizobacterium is capable of fixing nitrogen, protection against some forms of bacterial wilt, and even creates a host of beneficial plant hormones such as polymyxin,  and beta-amylase which are capable of solubilizing phosphorus into exchangeable form.(7) Interestingly, this strain of bacteria is even found in Neosporin®, because of its ability to produce compounds that are antimicrobial against bacteria that can cause human infection.

Bacillus Spp. – With Bacillus Spp., it creates hydrogen ions that encourage hydrolysis, which when combined with the organic acids it produces hydroxy carbolic acids which aids in solubilization of Silica.

Frateuria aurantia – This is a Proteobacteria species, named after Joseph Frateur, a Belgian microbiologist, that solubilizes Potassium. (8)
(8) – Frateuria, a New Genus for “Acetobacter aurantius”

Torulaspora globosa – Belonging to the Saccharomycetaceae family, that is known to help solubilize Potassium  (11)
(11) – Release of Potassium from Rock Powder by the Yeast Torulaspora globosa

Beneficial Bacteria

Bacillus subtilis – Here’s a champion when it comes to bacteria, used on an industrial scale. Because it can break down many forms of proteins and other organic compounds it plays a large role in regulation of the carbon and nitrogen cycle.  It promotes the viability and growth of lactobacillus, part of why our blend works so well with EM-1 or any form of EM-1 Kashi. (9)
(9) –  Improved growth and viability of lactobacilli in the presence of Bacillus subtilis (natto), catalase, or subtilisin.

Bacillus coagulans – This plant growth promoting bacteria in the Bacillus family produces lactic acids, plant growth promoting phytochemicals, and interacts positively with mycorrhiza. (10)
(10) – Effect of arbuscular mycorrhizal (AM) fungus and plant growth promoting rhizomicroorganisms on medicinal plant Solanum viarum seedlings.

Beneficial Fungi

Mycorrhizae – Mycorrhizae forms symbiotic relationship with the roots of a host plant.

Trichoderma harzianumThis fungus is often used as a biofungicide. It can be used as a seed treatment, foliar application, and soil treatment to suppress a variety of diseases including Botrytis, and Fusarium.
