Abstract
A process and composition for controlling slime in industrial waters by the control of slime-forming fungi in the waters. The process comprises the step of adding an effective amount of a polyene antibiotic, such as nystatin, to the waters. The composition is a polyene antibiotic suspension comprising (i) a polyene antibiotic such as nystatin, (ii) a suspension medium such as a glycol, (iii) a sufficient amount of a pH buffer such as an alkali metal phosphate to achieve and maintain the suspension at a pH of about 6-8, (iv) a viscosity modifier such as a heteropolysaccharide, and optionally (v) a surfactant.
