“…If the methane content in biogas is too low, it reduces the efficiency of the culture, and an excess of carbon dioxide in biogas is detrimental to methanotroph growth(Dizon et al, 2023). Impurities in biogas, such as H2S, have inhibitory effects on the growth of methanotrophs(Xu et al, 2020;Pei et al, 2022). Therefore, desulfurization and purification of biogas prior to use is essential(Tsapekos et al, 2019;Xu et al, 2020).…”

The escalating global demand for protein and the imperative to meet sustainable development goals have driven the emergence of biotransformation platforms, with methanotrophs showing significant potential in this field. In this paper, the metabolism, nutritional requirements, cultivation strategies, and bioreactors of methanotrophs are reviewed. Integrating upstream and downstream technologies is also advocated to advance the development of methanotroph biotransformation platforms toward a circular economy model. The advancements in utilizing biogas as a viable carbon source and wastewater as a nitrogen source are discussed, emphasizing the need for detailed quality control and safety assessments to ensure the suitability of single-cell protein as animal feed. In general, by integrating advanced nutrient recovery technologies to define new process routes, methanotroph biotransformation platforms can bring better environmental benefits by reducing carbon emissions and saving resources. Shifting to renewable energy is crucial for achieving environmental sustainability. By using renewable energy to power microbial fermentation, biomass dehydration, and waste recycling, the platform can offset high energy consumption and attain significant market competitiveness with traditional protein sources.
