| Abstract | In the current global context marked by a growing population and rapid urbanization, there are pressing challenges related to shrinking arable land and the effective management of an everincreasing volume of wastewater. The food industry, while holding the potential to address these challenges through improved techniques and exploring alternative dietary resources, is itself a significant contributor to these issues. Industry's operations demand substantial water and energy resources while generating a substantial volume of wastewater characterized by organic pollutants and nutrient richness. Microalgae-based wastewater treatment exhibits the capacity to reduce inorganic nutrient loads, sequester carbon dioxide, and minimize greenhouse gas emissions while inhibiting the proliferation of pathogenic bacteria. Therefore, an integrated approach that combines both microalgae and bacteria emerges as a comprehensive solution, addressing the challenges of reducing organic and inorganic waste simultaneously while leveraging their symbiotic contributions to biogeochemical cycling processes. By concurrently applying algae and bacteria, the wastewater management system can be significantly enhanced, thereby reducing the associated carbon footprint related to mechanical aeration for CO2 and O2, which would be necessary if these organisms were cultivated independently. Additionally, this integrated system generates a substantial amount of residual microalgal biomass, which can play a pivotal role in biorefinery concepts, enhancing economic viability. The remaining biomass can also be utilized for fermentation to produce methane or ethanol, promoting sustainable development and a transition to a circular economy. This review paper outlines various methodologies for the simultaneous utilization of microalgae and bacteria in wastewater management. |
