[Spheroplasts of Torulopsis candida yeasts and their oxidizing activity].
The paper describes the conditions in which the spheroplasts of the yeast Torulopsis candida IBFM-Y-127 with a high respiration rate can be isolated. The preliminary incubation of the cells with SH-reagents has to be carried out in a buffer without an osmotic stabilizer, and the incubation in a medium containing 0.6 M KCL, 0.1 M MgSO4, 0.1 MKH2PO4, pH 5.2. In these conditions the cells are incubated with the enzyme from Helix pomatia during 15 to 20 minutes, and the yield of the spheroplasts is 95 to 100 per cent. The spheroplasts oxidize various substrates (glucose, acetate, ethanol) at the same, or even higher, rate as the intact cells.
