What does the published scientific research say about Glomus microaggregatum?

Four peer-reviewed PubMed studies reference Glomus microaggregatum — also classified as Rhizoglomus microaggregatum — in plant-input contexts. The literature documents it as a naturally occurring arbuscular mycorrhizal fungus (AMF) detected in rhizosphere soil and roots across multiple geographies, not as a tested commercial inoculant product.

Research from southeast China found Glomus microaggregatum among the most common AMF species in rhizospheres of two heavy metal hyperaccumulators — Pteris vittata (arsenic) and Sedum alfredii (zinc/cadmium) — at both contaminated and uncontaminated field sites. No efficacy trials or registered label claims appear in this four-study set; what the peer-reviewed research on Glomus microaggregatum shows is ecological occurrence across diverse host plants and soil conditions, not regulated performance outcomes.
