A species name identifies a taxonomic group. A strain or isolate designation identifies more specific material within that group. MegaMyco names Rhizophagus irregularis. Research on a particular strain cannot establish the result for every product containing the species.
Keep the context.
Biological compatibility, successful colonisation and a measurable plant response are different questions. The growing conditions matter, and general research is not a promise of a particular result with MegaMyco.
