Fig. 5From: Flocculation characteristics of a bioflocculant produced by the actinomycete Streptomyces sp. hsn06 on microalgae biomassThe effect of flocculation conditions including different algal temperature (a), algal pH values (b) and metal ions (c) on flocculation activity of bioflocculant. All error bars indicate the SE of the three biological replicates. **represents a statistically significant difference of p < 0.01 compared with positive controlBack to article page
