ABSTRACT

Adsorption of Agrobacterium tumefaciens cells to potato tuber disks reached equilibrium after coincubation for about 30 min. More than 10% of the number of bacteria bound at equilibrium were adsorbed within 30 s. Adsorption isotherms obtained at three temperatures showed that the heat of adsorption was nearly zero.
