title: ATPase activity in cells of the yeast Saccharomycopsis fibuligera during mycelial growth.
abstract: Levels of ATPase activity were examined in the cells of Saccharomycopsis fibuligera during mycelial growth. The mycelial cells (M-form cells) grown under standing culture conditions exhibited a marked increase of ATPase activity after 3 days, showing a broad peak between 5 and 20 days and a maximum at 10 days. The dry weight/ml of the yeast-like cells (Y-form cells) grown under shaking culture conditions reached its peak after 3 days and remained constant throughout the 10 day period of observation. The dry weight/ml of the M-form cells under standing culture conditions exhibited its peak in 10-15 days and then gradually decreased. A very small amount of Y-form cells among the M-form cells under standing culture conditions, exhibited very low ATPase activity even in 10 days' incubation. In M-form cells, the particles increased in number during 20 days of incubation.
