Bioremediation of <i>p</i> -nitrophenol using an indigenous algal strain <i>Tetradesmus</i> sp. NITD18: a sustainable approach

Abstract The present study assessed the capability of Tetradesmus sp . NITD18, a green algal strain collected from the run-off water of a gas producing industry at Durgapur, for removing p -nitrophenol (PNP) from synthetic wastewater. The maximum removal efficiency of 59.64 ± 0.30 % was observed at an initial PNP concentration of 5 mg/L, initial pH 7, inoculum size of 15 % (v/v), and an incubation period of 15 days. The effect of pH (7–12) and inoculum sizes (5–15 %) on the removal of PNP using the test strain was assessed by varying these parameters judiciously. The results suggested that the Tetradesmus sp. NITD18 strain has considerable potential for PNP removal from wastewater.
