originating from the Greek "edaphos" for earth.
Edaphon translates as "soil organism", not precisely
"soil-based", but to me it is one and the same thing.
Incidentally, I reversed your language pair.

Mais l'étude détaillée des gènes de Bacillus cereus a permis de montrer que cet ancêtre commun n'est probablement pas une bactérie du sol, comme on le pensait jusqu'ici. Les bactéries du sol possèdent une très grande diversité d'enzymes servant à la dégradation des glucides, en rapport avec les nombreux types de glucides présents dans les sols. Ainsi, Bacillus subtilis, une bactérie du sol, en possède 41.

Bactérie du sol, non pathogène, Bacillus subtilis est un organisme de choix pour l'étude de la sécrétion protéique et un des outils génétiques les plus aisément manipulables avec la levure.

Probiotic B / Flora Balance TM is a revolutionary enhanced non resident soil based organism "Bacillus Laterosporus" (BOD Strain), a viable microorganism. Taken daily, originally intended in nature through ingestion of raw vegetables and fruits, Probiotic B / Flora Balance TM helps maintain a healthy colon and repopulates the intestines with beneficial bacteria, not the pathogenic bacteria so prevalent in our system's today.

Soil Based Organisms (SBOs) (Bacillus Subtilis and Bacillus Lichenformis) have been shown to inactivate HIV, SIV and other lipid-enveloped viruses, along with mycoplasmas, fungus and bacteria by producing 'surfactin' - a lipopeptide antibiotic. Lipid-enveloped viruses include: HIV, HHV-6 (strains A and B), EBV, CMV and herpes.

In one follow-up of the effects of SBOs on 100 people, all but one reported some sort of improvement. SBOs cause a favorable shift in the TH1/TH2 balance. Adverse reactions seem to be limited to excess dosage or a die-off of other organisms as cellular immunity is enhanced. While many noticed improvements in the first two weeks, some required up to 2 or 3 months of use before they found benefit.

Good soil should contain a healthy mixture of Soil-based Organisms (SBOs). These are naturally occurring micro-organisms that release powerful enzymes responsible for keeping it free of moulds, yeasts, fungi and other parasites which would otherwise make normal plant growth impossible.
When people ate vegetables grown in such nutrient-rich soil, they automatically ingested these organisms, which also had a beneficial effect on the digestive tract. The SBOs kept us free from pathogenic bacteria and putrefying waste matter that clogs up the colon, causing many diseases. As humans, we too need a rich and fertile environment of friendly micro-organisms within our systems in order to sustain optimum health.
