Teraganix sells an EM formulation called PRO-EM1 which is marketed as a gut probiotic. A list of bacterias and yeast used in this EM variation is included on their website:
(all quotes are going to be from wikipedia)
•
Lactobacillus plantarum: "[..] is commonly found in many fermented food products as well as anaerobic plant matter. It is also present in saliva."
•
Lactobacillus casei : "[...] is found in the human urinary tract and mouth. This particular species of Lactobacillus is documented to have a wide pH and temperature range, and complements the growth of L. acidophilus, a producer of the enzyme amylase (a carbohydrate-digesting enzyme)."
•
Lactobacillus fermentum: "[...] is associated with active dental caries lesions. It is also commonly found in fermenting animal and plant material. It has been found in sourdough."
•
Lactobacillus bulgaricus: "Lactobacillus delbrueckii subsp. bulgaricus is the main bacteria used for the production of yogurt. It is also found in other naturally fermented products."
•
Saccharomyces ceravisiae: "Saccharomyces cerevisiae is a species of yeast. It has been instrumental to winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes."
•
Rhodopseudomonas palustris: "Rhodopseudomonas palustris is a rod-shaped gram-negative purple non-sulfur bacterium, notable for its ability to switch between four different modes of metabolism."
Although PRO-EM1 is marketed as having a different formulation specifically for use as a human probiotic, it seems reasonable to speculate that L. casei might be the outlier component in this regard. Regardless of this being the case, the main take away is that Rhodopseudomonas palustris may likely be the species of purple bacteria used in EM - 1, and the other bacterias and yeasts are common to fermentation and easily obtained within local environments.
Rhodopseudomonas palustris is a very cool organism with surprising and strange abilities:
•"R. palustris is found extensively in nature and has been isolated from swine waste lagoons, earthworm droppings, marine coastal sediments and pond water."
•"R. palustris can grow with or without oxygen, or it can use light, inorganic or organic compounds for energy. It can also acquire carbon from either carbon dioxide fixation or green plant-derived compounds. Finally, R. palustris is also capable of fixing nitrogen for growth."
•"It was found that R. palustris can deftly acquire and process various components from its environment, as necessitated by fluctuations in the levels of carbon, nitrogen, oxygen and light."
•"R. palustris has genes that encode for proteins that make up light-harvesting complexes and photosynthetic reaction centres. LH complexes and photosynthetic reaction centers are typically found in photosynthetic organisms like green plants. Moreover, R. palustris can modulate photosynthesis according to the amount of light available, like other purple bacteria."
•Steiner aficionados out there might find this interesting: "TIE-1 [a specific strain of R. palustris] curiously takes in electrons from materials rich in iron, sulfur and other minerals found in the sediment beneath the surface. In an extraordinary strategy, as the microbes pull electrons away from iron, iron oxide crystallizes in the soil, eventually becomes conductive, and facilitates TIE-1 in oxidizing other minerals."
R. Palustris is able to produce and eat electricity by making soil conductive.
