Abstract: ABSTRACT OF THE INVENTION "A PROCESS FOR BACTERIAL BIOFILM FORMATION ON 5 LIGNOCELLULOSIC RESIDUES FOR APPLICATION IN OIL DEGRADATION" Water pollution caused by the presence of oils contributed by industries and oil spills causes severe ecological imbalance. This invention explores the biofilm formation of bacteria on lignocellulosic materials, for enhanced oil degradation in water 10 bodies. The biofilm acts as a stable platform, facilitating sustained microbial activity and efficient hydrocarbon breakdown through enzyme production, particularly lipases. Quantitative and qualitative analyses, including DNA quantification and emulsification index tests, confirm robust biofilm formation and significant enzyme secretion. The process was further optimized to maximize lipase activity, improving biodegradation 15 efficiency. By repurposing agricultural waste as a natural biofilm support, this approach offers a sustainable, cost-effective, and eco-friendly solution for oil spill cleanup and industrial wastewater treatment. The integration of microbial immobilization on lignocellulosic residues not only enhances enzymatic degradation but also promotes waste valorization, making it a promising strategy for environmental bioremediation. 20 Figure 1 shows the steps involved in the process of bacterial biofilm and further application in oil degradation. Figure 2 shows the flowchart of the detailed pretreatment process on lignocellulosic residues Figure 3 shows the flowchart of the detailed biofilm production process on 25 lignocellulosic residues
