Food-grade utilization of bovine slaughterhouse by-products for developing cost-effective media supplements in cultivated meat applications

Food Science of Animal Resources · 25 June 2026 · DOI 10.1007/s44463-026-00088-3

Bovine slaughter by-products were assessed as food-grade media ingredients for cultivated meat. The review examined muscle growth and repair biology, satellite cells, myogenic regulators, drawbacks of fetal bovine serum, and alternatives including recombinant proteins, food-derived components, and adult livestock serum. Compositional analysis found that blood and organs provide proteins, amino acids, fats, and minerals relevant to muscle cell growth and maturation. Plasma and serum had different functional profiles, while liver, heart, spleen, tongue, and other tissues contained varying nutrients that could support lower-serum or serum-free media.

Deciphering the Reversible Adaptation of PK15 Cells to Serum-Free Suspension Culture: A Stepwise Strategy and Molecular Insights

Porcine PK15 kidney epithelial cells adapted better through staged serum reduction than direct reduction, offering a possible route to scalable seed cell growth for cultivated meat. Researchers compared both methods, moved low-serum adherent cells into serum-free suspension, returned them to adherent culture, and analysed gene expression. Sequential adaptation preserved proliferation, cell-cycle progression and epithelial traits, while suspension cells shifted towards more efficient energy use. Re-adherence partly restored morphology, growth features and oxidative-stress measures. Reversible genes centred on adhesion and metabolism, making staged adaptation the stronger method tested.

Sustainable proteins for future food systems: nutritional quality, environmental trade-offs, and consumer acceptance

A multidisciplinary review compares plant, microbial, algal, insect, fermented and cultivated proteins to assess their role in future food supply and the trade-offs that could limit it. The authors examine amino acids, digestibility, micronutrients and health effects, alongside life-cycle measures and evidence on consumer uptake. They identify tensions around processing, energy use and production scale. Taste, culture, price and aversion to unfamiliar foods also affect adoption. The proposed framework shows that no single measure can judge protein alternatives.

From residual biomass to novel feed ingredients for pigs, broilers and fish: A methodology for integrating feed formulation and consequential life cycle assessment

Researchers combined market-based feed formulation with consequential life cycle assessment to test four residual-biomass ingredients in diets for pigs, sows, broilers and fish. The options were bacterial protein using manure-derived methane, fungal protein using sugars from wheat straw, protein concentrate from sugar beet leaves, and black soldier fly meal produced on food waste. Bacterial protein delivered the largest environmental gains across species, reflecting its production impact, dietary inclusion level and reduction of soybean meal. Standard substitution proxies overstated climate savings by 14–38%.
