Enzyme-mediated dye degradation
Fusarium venenatum A3/5 used waste-relevant carbon sources in markedly different ways, affecting feedstock choices for mycoprotein production. Researchers combined microlitre cultures, optical-density calibration, UHPLC time series and Gompertz models. Glucose and sucrose enabled fast growth but produced low biomass yields and substantial ethanol. Fructose gave the highest yield, at 0.49 g/g, while lactose consumption reached only 34% after 234.5 hours. An expired functional drink produced 18.37 g/L biomass, versus 12.49 g/L for a matched synthetic control. Beverage waste was the strongest tested feedstock, but evidence covers one real waste stream.

Electrohydrodynamics and Fluid Dynamics
Gelatin-coated alginate microcarriers supported muscle cell culture in static and agitated systems, suggesting an edible scaffold for cultivated meat production. Researchers electrosprayed spherical, 242 µm alginate particles, coated them with gelatin, and seeded them with mouse myoblasts and immortalised bovine satellite cells at two densities for seven days. Both cell types remained viable and proliferated under static conditions, with metabolic activity similar to 2D cultures. Agitation slightly reduced proliferation, but metabolic activity and carrier structure remained stable. The early shake-flask evidence warrants further scale-up testing.

Viral Infectious Diseases and Gene Expression in Insects
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.
