Increase in xylitol production by Candida tropicalis upon addition of salt

Optimization of pH and acetic acid concentration for bioconversion of hemicellulose from corncobs to xylitol by Candida tropicalis

“…Hydrolysis of lignocellulosic materials always goes together with the formation of byproducts that inhibit the fermentation process [3]. Hemicellulose hydrolysate can be converted to xylitol by several microorganisms including Pichia and Debaryomyces also Candida [4][5][6][7]. Among these, Candida ferments xylose to xylitol in a high yield and productivity.…”

Evaluation of nutrient supplementation to charcoal-treated and untreated rice straw hydrolysate for xylitol production by Candida guilliermondii

“…yeast extract and peptone) and various minerals have been used to supplement xylose culture media for xylitol production by yeasts (Azuma et al, 2000;Walter et al, 2001;Canettieri et al, 2001). However, when hemicellulose hydrolysates are used as culture media, the need for supplementation should be minimised, since they contain not only fermentable sugars, but also compounds that are essential for cell growth (Preziosi-Belloy et al, 2000;Canettieri et al, 2001).…”

Xylitol production is increased by expression of codon-optimized Neurospora crassa xylose reductase gene in Candida tropicalis

“…Previous reports have described attempts to minimize glucose repression of XR in C . tropicalis by supplying sodium chloride in culture medium, or by optimizing the fermentation process [24, 25]. However, these approaches do not guarantee permanent expression of XR in cells.…”
