In biofilm assay, the relative absorbance was reduced in pres- ence of LGO due to less viability and adherence. Even at a lower concentration (0.03 ll/ml) of LGO only 30% of relative absorbance was observed. The biofilm activity was reduced at sub MIC level and increased concentration of LGO further reduced the cell adher- ence or biofilm formation. At an increased concentration of 0.5 ll/ ml the biofilm formation was completely inhibited when com- pared with the control. Even at lower concentrations of LGO (0.25 and 0.12% concentration), relative reductions of 90.9 and 87.5% biofilm inhibition were observed respectively (Fig. 3). Micro- scopic assay of biofilm formation also revealed that low concentra- tion below the MIC inhibited biofilm formation (Fig. 4). From the present study, it is evident that LGO exerted a toxic effect on C. albicans with antifungal and antibiofilm activity. This may be due to disruption of cellular structure and function, inhibiting several cellular activities such as membrane synthesis, respiration, and germination that are required for growth (Wilkinson and Cavanagh, 2005). The phytochemicals such as 4-tert-butylcalix, panaquinquecol 7 and boronic acid, diethyl-, 3, 4-dihydro-1- naphthalenyl ester interrupted cellular growth and function. Fur- ther, it decreased the adherence ability of C. albicans by inhibiting
