Estimation of total glycogen in cells was performed asdescribed previously (Parrou et al., 1997) with slightmodifications.Briefly, YPD medium-grown C. glabratacells were harvested, washed once with 1 ml ice-cold waterandresuspendedin 250 μl sodium carbonate(0.25 M)solution. After incubation at95 ̊C for 4 hin water bath with occasional stirring, cell suspension was cooled and pH of the suspension was adjusted to 5.2 by adding 150 μl 1 M acetic acid. Tothis suspension,600 μl 0.2M sodium acetatewas added and cell suspension was incubated with 1-2 U/ml of α-amyloglucosidase from A.niger(Sigma #A7420)at 57 ̊C for overnight with constant agitation.Resultant glucose liberated by α-amyloglucosidase digestion was collected in the supernatant fraction and quantifiedby phenol-sulphuric acid methodof carbohydratedetermination.For quantification, commercially available purified glucose was used as a standard and total glycogen incells was expressed as μg/2 x 107cells tonormalizeagainstcell density
