Abstract

In the present study, we optimized the parameters for maximum yield of xylitol and ethanol by Candida tropicalis strain LY15 utilizing different Hemicellulosic Waste substrates (HWs) obtained by Acid-Alkaline hydrolysis method. Using the pomegranate peel as substrate, higher yield of xylose reductase, xylitol and ethanol were obtained. The optimal level of variables such as inoculum, HWs concentration, time period and RPM (agitation speed) were determined by the response surface methodology, with a significant co-efficient determination of R2= 0.89. Positive correlation was obtained with our experimental and predicted values. The interactions with the ideal levels of inoculum (1%), HWs (Pomegranate peel) (2%), time period (60 h) and RPM (140) showed highly significance values of xylose reductase (171.5 IU/mL), xylitol (55.57 g l-1) and ethanol (3.37 g l-1) at an incubation period of 60 h. The dual yield produced by Candida tropicalis strain LY15 using pomegranate peel makes the organism potent candidate for industrial application.
