The use of the biotechnological way to xylitol production can represent minors production costs, whereas, in this case, it can be worked under reduced conditions of pressure and temperature and does not have necessity of purification of the hydrolysate. Among the searched alternatives, the Submerged Fermentation method is more extensively studied, having been tested, in recent years, several process options and operational conditions. However, little it has been studied on the use of Solid Fermentation method to this bioprocess. Therefore, considering the promising advantages of Solid Fermentation on the Submerged Fermentation in many biotechnological processes, this article has as objective to demonstrate the potentiality and applicability of the use of Solid Fermentation for xylitol production. For this, it has been done preliminary assays using sugarcane bagasse as inert support and xylose commercial as substrate in polypropylene sachets inside a greenhouse. The fermentation runs were done using the xylose fermenting yeast – Candida guilliermnondii at 30o C, under oxygen limited conditions. |
