• Mycorrhizas are ubiquitous and most agricultural crop plants are mycorrhizal, and some soil bacteria can grow at the
expenses of AM fungi [42]. Developing PSMs that can form syntropic associations with these symbiotic fungi, mixed
with rhizosphere competent PSM might secure a better colonization of the roots and an inoculation success in soils with
diverse microbial communities. Industrial production of the obligatory symbiotic AM-fungi is not a problem anymore,
in fact Premier Tech produces commercially the AM fungus Glomus intraradices, used in their products like PRO-MIX
MYCORRHIZAETM [43].
