Invasive plant species threaten ecosystems and agriculture by reducing biodiversity and disrupting natural systems, while climate change continues to worsen due to fossil fuel use and rising greenhouse gas emissions. This project proposes converting invasive plant biomass into renewable energy as a sustainable solution. An engineered BL21 E. coli strain produces lipase to break down plant biomass into biodiesel precursors through physical processing followed by enzymatic hydrolysis and transesterification. Microalgae such as Schizochytrium, known for high lipid content, further enhances fuel production. Overall, the system aims to control invasive species, lower carbon emissions, strengthen energy security, and support sustainable biofuel development.
