Description
Summary:Due to the lack of water resources and the harmful effects of wastewater on environment and human health, treatment of wastewater becomes necessary. The present study explored the effect of musical sounds on the biological treatment of seafood canning wastewater by using Yarrowia lipolytica . Our results showed that low frequency (21 Hz to 1356 Hz) and high frequency (21 Hz to 16,214 Hz) musical sounds stimulated the growth of Y. lipolytica and increased the polluant removal efficiency. Such treatment decreased significantly the chemical oxygen demand (COD) and salinity as well as the color of this wastewater. Our study revealed that low frequency musical sounds are more effective in COD (87.5%) and salinity (44%) reduction as well as the decolorization (86.46%) of this effluent. Additionally, after 7 days of incubation significant yeast cell dry biomass (3.46 ± 0.22 g/L) and single cell proteins (46.45 ± 0.7 mg/g) were obtained under low frequency waves. Musico-bioremediation represents an innovative ecotechnological approach to wastewater treatment with low operating costs and significant environmental benefits.
