Effect of Speed of Incubator Shaker on Microbial Production of Xylitol

Sri Vani K and Pydisetty Y

The work is an experimental study on the effect of speed of incubator shaker on the microbial production of xylitol from xylose using Candida parapsilosis NCIM-3323 and the optimum values are obtained. The speed of the incubator shaker was varied from 50 rpm to 175 rpm at a temperature of 30oC, initial pH of 3.5 and initial xylose concentration of 60 g/l. It was observed that the maximum production of xylitol was obtained for the speed of incubator shaker of 100 rpm. It was found that maximum xylitol concentration of 14.2 g/l, maximum xylitol yield of 0.284 g/g, maximum xylitol volumetric productivity of 0.5458 g/l-h, maximum xylitol specific productivity of 0.0109 g/g-h were obtained for the speed of incubator shaker of 100 rpm.
