  The quantity of proteins and the reflocculating capacity of a lectinic protein extract from the yeast cell wall of K. apiculata mc1 increase as the concentration of glucose pulse was higher The study with fluorescent probe indicates that the surface receptors of  K. apiculata are galactose-specific and the number of lectinic sites increases with increasing glucose pulse Our results confirms that the mechanism  of  self-flocculation induction of Kloeckera apiculata mc1 by glucose implies de novo protein (lectin) synthesis that specifically interacts with the galactose residues on  the neighboring cells
