Abstract:
As the global demand for wine continues to grow, sustainable practices and resource management become increasingly important to preserve valuable natural resources. In fact, the water footprint is an issue of concern in the wine production sector, being influenced not only by the amount of water used but also by the quality of water discharged as effluent. The utilization of winery wastewater as a nutrient source for the mixotrophic cultivation of Chlorellavulgaris has been proven as a convenient and sustainable approach. Repurposing winery wastewater, not only does it reduce the environmental impact of winery effluent by decreasing its organic load, but it also addresses the water footprint associated with wine production. The analysis of winery effluents revealed significant variations in their chemical composition, including low levels of nitrogen and phosphorus, moderate sugar concentrations, and varying polyphenol levels. Despite nutrient limitations, the effluents sustainedChlorella growth under mixotrophic conditions, without the need for effluent neutralization. Incorporating effluent as an additional sugar source yielded positive results, significantly enhancing biomass production, and facilitating the generation of cost-effective biomass. However, determining the optimal percentage of effluent incorporation and identifying the ideal experimental conditions for maximizing its potential still pose challenges.
