Abstract
AbstractCephalexin (CFX), a β-lactam antibiotic which is identified for the treatment of different disease infections, has been reported as a micropollutant in wastewater released from sewage, hospital, or pharmaceutical industries. Chlorella pyrenoidosa-2378, a green microalgal strain, is recognized for its degradation ability against wastewater pollutants and the potential of the biomass it produces. In this present study, the cultivation process of Chlorella pyrenoidosa-2378 strain with CFX concentration of 50 mg/L, 100 mg/L, 150 mg/L, and 200 mg/L added to its culture medium labeled as test I, test II, test III, and test IV, respectively, is the process being observed for evaluation of its degradation ability and as sustainable approach for antibiotic degradation. chlorophyll a in test IV, chlorophyll b in test III, and carotenoid content in test I were observed to be higher in amount than control by 0.775 mg/L, .069 mg/L, and 0.356 mg/L, respectively. Using the HPLC method, the total removal efficiency was observed to be 79.09%, 86.26%, 89.62%, and 88.03% against 50, 100, 150, and 200 mg/L concentrations of CFX, respectively. The observations that C. pyrenoidosa-2378 remained stable while being used as an alternative bioremediation method, provide an alibi for its novelty and potentiality to be used commercially for biomass production and at industrial scale for degradation.
