Impact of cell density on virus titer. Reactors were inoculated with either 100,000 cells/Fibra‐Cel and cells were grown for 6 days in different temperatures or with various numbers of cells and cells were grown for 6 days under the same condition. At the end of growing phase, 120,000 (red), 220,000 (orange), 600,000 (purple), 750,000 (gray), 1,000,000 (green), or 2,000,000 (blue) cells/Fibra‐Cel were estimated. Virus titers were monitored for 2 days after infection with 0.1 MOI. MOI, multiplicity of infection; PFU, plaque‐forming unit
