N2  - Solid-state fermentation (SSF) has emerged as a sustainable method for valorizing  domestic waste into value-added products, particularly organic acids. This study  investigates the potential of SSF, utilizing Aspergillus niger as the microbial agent, to  produce organic acids from domestic waste under controlled conditions. The research  focuses on optimizing key parameters such as pH, temperature, moisture content, and  aeration to maximize product yield. The experimental setup involved the preparation of  domestic waste as the substrate, inoculation with A. niger, and fermentation over seven  days. Quantitative analysis was performed using Dinitrosalicylic Acid (DNS) assay and  High-Performance Liquid Chromatography (HPLC) to monitor glucose utilization and  organic acid production. Results indicated a significant reduction in glucose  concentration from 1.012 g/L on Day 1 to 0.287 g/L by Day 7, reflecting active microbial  metabolism. HPLC analysis identified acetic acid and formic acid as predominant products, with acetic acid accounting for the highest peak area percentage of 65.94%.  The study highlights the feasibility of SSF as an effective approach for domestic waste  valorization, contributing to waste management and circular economy goals.  Recommendations for further research include scaling up the process, enhancing  microbial strains for higher yields, and integrating advanced downstream processing  techniques to improve the recovery and purity of organic acids. This work underscores  the potential of SSF to transform waste streams into valuable biochemical products,  aligning with sustainable development practice
