Fig. 3From: Efficient biodegradation of chlorophenols in aqueous phase by magnetically immobilized aniline-degrading Rhodococcus rhodochrous strainOptimization of Fe3O4 NPs concentration in immobilization support. k-Carrageenan was used as the immobilization support. The effect of varying the Fe3O4 NPs concentration (0, 3, 6, 9, and 12 g/L) was investigated. The error bars in the figure indicate the standard deviation of three parallel replicatesBack to article page
