Methane is a potent greenhouse gas with a short atmospheric lifetime, making its removal critical for mitigating climate change. Methanotrophic microorganisms enzymatically oxidize methane at ambient temperatures, offering a biological route for mitigation. However, conventional liquid-based bioreactors face mass transfer limitations and scalability challenges. Here, we review studies of methanotrophic biofilms and explore their embedding within hydrogel matrices, which can enhance gas diffusion
