Abstract:
Activated sludge from four municipal waste disposal plants contained microorganisms which produced a viscous product when aerated with added methanol. Activated sludge from an industrial corn products firm made heteropolysaccharides only if acid was repeatedly neutralized. The influence of aeration, backseeding, and time of methanol feeding on viscosity and methanol utilization was examined in four 10-liter fermentations for 7 days. After methanol depletion, viscosity declined. Readily soluble, freeze-dried crude products were prepared. The crude product mixed with fertilizers or pesticides was shown, by other investigators, to have some promise as a slow-release agent.
