“…The interactions between biomass and adsorbent during the EBA process have been studied by various researchers Feuser et al, 1999;Gondkar et al, 2001;Hubbuch et al, 2006;Lahore et al, 1999Lahore et al, , 2000Lin et al, 2001Lin et al, , 2002Lin et al, , 2003aLin et al, ,b, 2004Lin et al, , 2007Mei et al, 2005;Vergnault et al, 2004Vergnault et al, , 2007. With an anion exchange adsorbent, electrostatic interactions retain the yeast cells which carry a negative surface charge.…”
