Abstract

Organisms were isolated from activated sludge and a sprinkling filter utilized for creamy waste purification. Their ability to utilize sugar without acid production and to decompose lactic acid was studied. When inoculated into a medium consisting of 0.1% glucose, 0.075% (NH₄)₂, HPO₄, and 0.02% KCl, adjusted to pH 6.4, growth without acid production occurred in eleven out of the thirty-nine organisms studied. With a similar medium, using lactose instead of glucose, growth with an absence of acid appeared in seventeen of thirty-nine organisms. Growth in most cases was slight, and but little of the sugar was decomposed, as determined by Fehling's solution.
