Figure 4From: High yield expression of an AHL-lactonase from Bacillus sp. B546 in Pichia pastoris and its application to reduce Aeromonas hydrophila mortality in aquacultureEffect of proteases on AHL-lactonase activity. The residual AHL-lactonase activity was determined after treatment with proteases at a ratio of 1:10 (w/w; protease/AiiAB546) at 37°C for 30 or 60 min. CK indicates no proteases added.Back to article page
