Statistical optimization of xylitol production from corncob hemicellulose hydrolysate by Candida tropicalis HDY-02

Xylitol production byCyberlindnera(Williopsis) saturnus, a tropical mangrove yeast from xylose and corn cob hydrolysate

“…C. guilliermondii when grown on wheat straw and rice straw resulted in differential xylitol yields of 0Á59 g g À1 (Canhila et al 2008) and 0Á72 g g À1 (Mussatto and Roberto 2004). C. tropicalis (Ling et al 2011) and D. hansenii (Prakash et al 2011) have also produced similar yields of 0Á73 g g À1 and 0Á69 g g À1 on corn cob and sugar cane bagasse hydrolysates, respectively. C. tropicalis ATCC 750, C. mogii ATCC 18364 and C. guilliermondii ATCC 20216 have also been shown to produce xylitol from big bluestem prairie grass hydrolysate in yields ranging from 0Á38 to 0Á46 g g À1 (West 2009).…”

Turning Maize Cobs into a Valuable Feedstock

“…Moreover, cobs have already been burned by early settlers and natives [7]. Besides the production of chemicals like furfural [8] or the sugar replacement xylitol [9,10], cobs are ground and used as absorbent (Complete Environmental Products, Inc, Pasadena, TX, USA; Green Products Company, Conrad, IA, USA), blasting material (Kramer Industries, Inc, Piscataway, NJ), and animal bedding [11]. When burning cobs to produce heat and energy for drying grain [12] or other purposes, the ash can be used to partly replace pozzolan in cement [13] or to be returned to the field to recycle minerals and microelements.…”

A Statistical Approach to Optimize Xylitol Production by <i>Debaryomyces nepalensis</i> NCYC 3413 <i>in Vitro</i>

“…By increasing its concentration to 10 g/l, it: resulted in a higher xylitol yield. It was also reported that increasing the concentration of K 2 HPO 4 in the medium could enhance the buffering capacity of the medium [20,28,29]. The concentration of xylose in the media affected the metabolism of the organism, with increased concentration of xylose, it was observed that the organism did not utilize xylose completely and the byproducts of its metabolism i.e.…”
