Quantification of alginate lyase activity. a Gram’s iodine method showing the clearance zone of twelve strains; b quantification of alginate lyase activities by Gram’s iodine method and ultraviolet absorption method. The enzyme activities of LJ-3 strain detected by both methods were taken as 100%, respectively. Each value represents the mean of three replicates ± standard deviation
