A systematic evaluation disclosed the following conditions to be optimum for the isolation of viable protoplasts from cultured cells of Nicotiana tabacum L. ;Bright Yellow' grown in liquid suspensions: (a) the cell culture in the early phase of cell number increase, (b) an enzyme mixture of 1% cellulase "Onozuka" and 0.2% Macerozyme, (c) an enzyme solution pH of 4.7 or 5.7, (d) a 2- to 3-hr incubation period, (e) 5 ml of enzyme solution per 500 mg cells and contained in a 50-ml Delong flask, (f) agitation on a gyrotory shaker at 50 rpm, and (g) 0.3 to 0.8 m mannitol as osmoticum in the cell enzyme mixture. The incubation temperature may be varied from 22 to 37 C. The procedure enabled 30% of the tobacco cells to form protoplasts, 80% of which regenerated cell walls in 4 days and 40% resumed cell division activity when returned to cell culture medium.
