Analysis of commercial fetal bovine serum (FBS) and its substitutes in the development of cultured meat.
Fetal bovine serum (FBS) is an extremely important culture growth supplement, accounting for approximately 60 % of cell-culture-media costs; therefore, lowering FBS-acquisition costs for the industrialization of cultured meat is imperative. This study attempted to produce an FBS substitute using discarded livestock by-products, with particular focus on formulating a product with a composition similar to that of FBS to improve effectiveness. However, to date, no study has precisely analyzed the commercial components of FBS, and this study is the first to compare the chemical composition of FBS and commercially available horse serum purchased from the United States or Europe with that of FBS substitutes developed by our team. This study analyzed the chemical composition of the FBS products purchased by our team over the past 3 years via blood, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and independent composition analyses. While the composition and quality of commercial FBS products are known to vary, the FBS composition of our purchased products was relatively uniform regardless of company, brand, or country of origin. In contrast, FBS substitutes obtained from three major livestock species (cattle, pig, and chicken) clearly exhibited differences in composition, a phenomenon that was also observed upon comparing with FBS as well as among different species. Therefore, to replace commercial FBS entirely, the production of a proportionately effective substitute product comprising an equal or similar composition is required, and the results of this study can be a steppingstone to achieving this. In addition, FBS substitutes manufactured using inexpensive slaughter by-products as raw materials are expected to ultimately reduce the unit cost of cultured meat production.
