No.Is it possible/practical to freeze agar slants for extended storage if glycerol was used as a substitute for mineral oil to prevent cell wall rupture? If an agar slant is viable with healthy yeast for 6~12 months at refrigerator temperatures, could freezing extend this by years with less concern for infection or genetic drift/mutation that can occur in “home freezing” (non-laboratory) settings?
