Bacterial single cell protein (BSCP): A sustainable protein source from methylobacterium species

Single Cell Protein (SCP) is a potential replacement for traditional protein sources in both food and feed. This review specifically focuses on SCP produced by bacteria, emphasizing its unique advantages such as rapid growth, high protein content, efficient manufacturing, genetic flexibility, and thorough strain characterization. Notably, among other microorganisms, Methylobacterium species have recently been found to be crucial for SCP synthesis. The review examines the feasibility of incorporating SCP as a sustainable substitute in protein diets for aquaculture and cattle production by closely analyzing fishmeal and soybean meal. Additionally, it highlights the importance of ongoing research and supportive legislation, while also considering economic and policy factors to assess the financial viability of SCP production. The review concludes by outlining future prospects and the outlook for SCP derived from Methylobacterium species, providing a forward-looking perspective on the evolving applications of SCP.
