From: Bioremoval of reactive dye Remazol Navy by kefir grains
Dye removal % by kefir grains: a at different pH values (Cdye = 100 mg/L, CKefir = 2.4 g/L, T = 25 °C), b at different temperatures (Cdye = 100 mg/L, CKefir = 2.4 g/L, pH = 3), c at different initial dye concentrations (CKefir = 1.2 g/L, T = 25 °C, pH = 2), d in consecutive batch processes (CKefir = 2.4 g/L, Cdye = 100 mg/L, T = 25 °C, pH = 2)
