EXPERIMENT OF A STRAIN WITH HIGH LIPOLYTIC-ACTIVITY IN INDUSTRIAL EFFLUENTS

From samples of effluent derived from a biological treatment plant of a mayonnaise and margarine producing factory, several bacteria strains presenting a high lipolytic activities (between 0.2 and 0.6 u/ml) wer e isolated. The strain having the highest activity (0.6 u/ml) was used for treating a typical final effluent and the results obtained were c ompared with those achieved with Yarrowia lipolytica and Saccharomycop sis lipolytica strains. The isolated strain showed a higher specific c apacity for reducing chemical oxygen demand (COD), about 38%, more tha n the other strains.
