Distinct Community Composition of Previously Uncharacterized Denitrifying Bacteria and Fungi across Different Land-Use Types.

abstract：:Due to their obligate symbiotic nature and lack of long-term storage methods, the strain collection of arbuscular mycorrhizal (AM) fungi requires periodic proliferation using a pot culture with host plants. Therefore, a method to evaluate the purity of proliferated AM fungal cultures is critical for the quality contro...
