Abstract T4 lysozyme pilot-scale fermentation was studied. T4 lysozyme was induced and expressed by Pichia pastoris in the 200L fermentor. The yield of target protein was 1.69g /L with 192U/mg enzyme activity in the broth. The enzyme protein was freeze-dried. The weight of enzyme powder was 211.1g. T4 lysozyme content was 68.9%, and activity was 182U/mg in enzyme powder. The total yield was 66%. The T4 lysozyme pilot-scale process line was established successfully.
