Degradation of antibiotics by bacteria and fungi from the aquatic environment

The potential of using bacteria and fungi from aquatic environment to degrade a mixture of two antibiotics, ciprofloxacin and erythromycin, was investigated. The antibiotics were added to river water at a concentration of 4 and 120 mg.L-1 for ciprofloxacin and erythromycin respectively. Three variations of the study unit were setup. The first having increased phosphate concentration; the second having slight...

Adsorption of Rhodamine B dye from aqueous solution onto acid activated mango (Magnifera indica) leaf powder: Equilibrium, kinetic and thermodynamic studies

Acid activated mango leaf powder (MLP) was employed for removal of the rhodamine B (RB) dye from aqueous solution. Batch adsorption studies were carried out under varying conditions of dye concentration, adsorbent dose, particle size, contact time, pH, and temperature. Removal efficiency was 77% in 45 min with 6.0 pH, 25 g/L as dose, 250 mg/L RB concentration and 30°C temperature. The equilibrium data the best...
