The fermentation of ethanol from cheese whey was optimized with respect to temperature, pH, and rpm. A comparative study was performed between immobilized and free cells to get the maximum ethanol production Results revealed that 35°C temperature, 4.5 pH and 60 rpm is the optimized condition for yeast immobilized in agarose bead. Similarly, 35°C temperature, 5.0 pH, 60 rpm is the optimized condition for yeast immobilized in alginate bead and 35°C temperature, 5.0 pH, 80 rpm is the optimized condition for the free yeast cell respectively. Immobilised cell resulted 4.25% ethanol with alginate bead whereas 4.35% with agarose bead and 4.30% with free cell after three days of incubation under optimized conditions. When the same cell immobilized beads were reused, obtained 1.8% ethanol with agarose and 1.7% ethanol with alginate bead.</p><p>DOI: <a href="http://dx.doi.org/10.3126/jncs.v30i0.9388">http://dx.doi.org/10.3126/jncs.v30i0.9388</a></p><p><em><strong>Journal of Nepal Chemical Society</strong></em></p> <p>Vol. 30, 2012</p> <p>Page:  159-164</p> <p><strong>Uploaded date</strong>: 12/20/2013</p> <p> </p><p> </p>}, journal={Journal of Nepal Chemical Society}, author={Shrestha, Smita and Shrestha, Fedip and Rajbhandari, Prajwal and Baral, Ramesh and Suwal, Shyam Krishna and Joshi, Jarina}, year={2013}, month={Dec.}, pages={159–164} }
