Analysis of Fungal Flora and Isolation of Fungi for Soil Regenerating Material, SATOGEN

Abstract

SATOGEN, a soil regeneration material, can suppress plant diseases and promote low-temperature fertilization. The fungal flora was examined with the aim of identifying the fungal species responsible for these functions. SATOGEN was composed of Amoebozoa (15.6%), Archaeplastida (2.0%), Excavata (16.2%), Opisthophyta (15.8%), SAR (39.1%), and others. Amoebozoa was dominated by Mastigamomeba (12.2%) and SAR was dominated by Paraphysomonas (28.5%). Fungi with soil regenerating activity were isolated from SATOGEN, resulting in 56 species in 38 genera. Rhodotorula mucilaginosa was isolated under wood component growth conditions. Actinomucor, Aspergillus 7 species, Blastobotrys, Byssochlamys 2 species, Candida 3 species, Cephalotheca, Cephalotrichum, Chaetomium, Cladosporium, Cryptococcus, Cyberlindnera 2 species, Eupenicillium, Eurotium, Geomyces 2 species, Hypocrea, Kluyveromyces 2 species, Lepidosphaeria, Metarhizium, Mortierella 2 species, Mucor, Paecilomyces, Paecilomyces, Penicillium 5 species, Phanerochaete, Phialemonium, Pichia, Pseudogymnoascus, Pseudozyma, Rhizopus, Rhodotorula, Saccharomyces, Simplicillium, Sporothrix, Sugiyamaella, Taeniolella, Talaromyces, Thielavia, Trichoderma 2 species and Trichosporon were isolated under the main fungal conditions. In most of these fungi, woody matter degrading activity, plant disease fungus inhibitory activity, and plant growth promoting activity have been reported.
