University of the Ryukyus
The pseudoscientific concept of "friendly microorganisms" was developed by professor Teruo Higa, from the University of the Ryukyus in Okinawa, Japan. He stated in the 1980s that a combination of approximately 80 different microorganisms was capable of positively influencing decomposing organic matter such that it reverts into a "life-promoting" process. Higa invoked a "dominance principle" to explain the asserted effects of his "Effective Microorganisms". He claimed that three groups of microorganisms exist: "positive microorganisms" (regeneration), "negative microorganisms" (decomposition, degeneration), "opportunist microorganisms" (regeneration or degeneration). Higa stated that in every medium (soil, water, air, the human intestine), the ratio of "positive" and "negative" microorganisms was critical since the synergistic symbiotic microorganisms followed the trend to regeneration or degeneration. Therefore, he claimed that it was possible to positively influence the given media by supplementing with beneficial microorganisms.
