In my present study AMF spores were As the streak progresses the spores become more and more separated till finally individual colonies, arising from few or single spores, are obtained. The fungus may be re-grown by dipping a sterile applicator stick into the water suspension, thereby retrieving some fungal cells, and aseptically inoculating them into a desired culture medium. Preserving yeast and mold isolates ensures long Fungal spores exhibit exceptional stress resistance, with some surviving over 17 years in dormancy.
