Influence of fluid velocity and cell concentration on the transport of motile and nonmotile bacteria in porous media
Article Abstract:
A study investigated the effect of fluid velocity on the transport of motile and nonmotile bacteria in saturated soil columns using radiolabeled cells. Results reveal that filtratrion theory can not be applied for motile bacterial strain at low fluid velocities. There was a variation in cell retention seen in motile cells that contradicts colloid filtration theory, which states that an reducing the bulk fluid velocity in a porous medium increases the number of collisions of passive colloids with particles.
