Abstract

Nejayote wastewater, a byproduct of maize nixtamalization, contains high levels of alkalinity and organic matter, posing environmental challenges if not adequately treated. This study investigates the bioremediation potential of an alkali-tolerant yeast strain for treating nejayote wastewater. The yeast strain, identified for its resilience to alkaline conditions, was cultured in nejayote wastewater under controlled laboratory conditions. Parameters including pH, chemical oxygen demand (COD), total organic carbon (TOC), and microbial biomass growth were monitored throughout the experiment. Results demonstrate significant reductions in COD and TOC levels following yeast treatment, indicating effective organic pollutant degradation. The study highlights the yeast's ability to thrive and remediate nejayote wastewater, offering a sustainable approach to mitigate environmental impacts associated with maize processing residues
