✦ Synopsis
To define some aspects of the biological corrosion sulphate-reducing bacteria were studied in paper machine waters and in plugged perforations of a suction roll. The desulphuricants were most active on passive fiber recipients. Most bacteria found in fiber plugs taken from the perforations of suction rolls belonged to the genus Desulfovibrio. Desulphuricants were found mainly at the outer ends of plugged perforations, where corrosion of the roll metal is most evident.
Sulphate is dissimilatory reduced by bacteria of the genera Desulfovibrio and Desulfotomaculum. Desulphuricants may be involved in corrosion either indirectly, by pro-
