Statistical analysis for flocculating activity at 0.1–2.0% bioflocculant dosage.

Dosage (%)	Flocculating activity (%)	P value*	Homogenous subset**
0.1%	79.8 ± 1.65	P ≤ 0.05	a
0.5%	94.2 ± 0.44	P > 0.05	c
1.0%	93.2 ± 1.01	P > 0.05	c
1.5%	93.6 ± 0.72	P > 0.05	c
2.0%	86.6 ± 1.78	P ≤ 0.05	b

*The mean difference between groups is significant at 0.05 level.

**Homogenous subset is in ascending manner from lowest to the highest mean value.
