In this study, the biosorption of Cu2+ by <em>Pseudomonas putida</em> immobilized on loofa sponge (<em>Luffa cylindrica</em> L.) was investigated. Effects of the particle size of loofa sponge, initial pH, temperature, initial Cu2+ concentration and the stirring speed on the adsorption of Cu<sup>2+</sup> were examined. Optimum conditions were determined as follows: loofa sponge particle size is 0.42 - 0.85 mm, initial pH is 5.0, temperature is 30 °C, initial Cu<sup>2+</sup> concentration is 25 mg/l, and stirring speed is 130 rpm. According to the results of kinetic calculations, Qmax and ro values were determined as 0.394 mg/g and 0.077 mg/g.min for <em>P. putida</em> immobilized on loofa sponge, respectively, while they were found to be 0.096 mg/g and 0.052 mg/g.min for the loofa sponge only. It is thought that Cu<sup>2+</sup> can be removed effectively from the wastewaters by using <em>P. putida</em> immobilized on loofa sponge.</p>}, number={2}, journal={ Natural Science and Discovery}, author={SIHOGLU TEPE, Arzuhan and KACMAZOGLU, Emine and OZTOP, H.
