The effect of the addition of amino acids on the microfiltration behavior of Escherichia coli ( E coli ) and Corynebacterium glutamicum ( C glutamicum ) slurry was examined using a dead‐end microfilter. It was found that the average specific filtration resistance, α av , of a slurry of microorganisms increased markedly by adding amino acids. Amino acid concentration ranged from 110 to 876 mol m −3 . However the same concentration of ammonium chloride did not increase α av . The cells were found to disperse in the presence of lysine, and this caused an increase in α av . In the case of kaolin slurry, α av was not affected by adding amino acids. Copyright © 2004 Society of Chemical Industry
