Microalgae cultivation for the treatment of anaerobically digested municipal centrate (ADMC) and anaerobically digested abattoir effluent (ADAE)

The successful cultivation of microalgae in wastewater establishes a waste to profit scenario as it combines treatment stream with production valuable end-products. Here, growth and nutrient removal efficiency three different locally isolated microalgal cultures (Chlorella sp., Scenedesmus mixed consortium) cultivated anaerobically digested municipal centrate (ADMC) abattoir effluent (ADAE) was evaluated. No significant differences (P > 0.05) specific rate biomass productivity were recorded between Chlorella monocultures the culture grown both effluents. sp. found incapable ADMC ADAE throughout period resulting collapse no further measurements on growth, this alga effluent. Fq´/Fm´ values which represent immediate photo-physiological status be negatively inhibited when effluents period. recovered back normal (?0.6) after an initial drop. Ammonium rates significantly higher (?2 folds) for compared cultures. Nonetheless, observed phosphate total protein carbohydrate content produced similar using ADMC. However, chlorophyll carotenoids < than Overall, monoculture most efficient option treating while simultaneously generating rich (up 49%) that can potentially exploited aquaculture feedstock.
