The yeast has the ability to accumulate the metals into its cells, taking the toxicity away from the soil and plants.
Lastly, Saccharomyces has natural antifungal properties. Likely the reasons its commonly used as a probiotic for human consumption and used in baking and brewing. Studies show that the yeast undergoes specific changes in gene expression when confronted with fungi.
By producing a compound called Chitinase, an enzyme that breaks down chitin, Saccharomyces renders pathogenic fungi useless.
The last of the microbial groups used to make EM-1®, Rhodopseudomonas palustris, is the most unique in that it is found in almost any environment in nature. The bacteria is so versatile, it can grow using any of the four modes of metabolism for life.
The photosynthetic bacteria is found naturally in livestock lagoons, soil, marine sediments and pond water and the human digestive tract. With soil and plant health, Rhodopseudomonas has been shown to impact plant growth by influencing structure and composition in the roots.
Although the exact mechanisms is not known and needs further study, it is thought that the bacteria affect important growth compounds such as auxins. The photosynthetic bacteria also plays a significant role in organic matter decomposition. The bacteria is a great addition to the soil, as it enhances nutrient uptake by cycling nitrogen into plant available forms.
