Evaluation of sorghum straw hemicellulosic hydrolysate for biotechnological production of xylitol by Candida guilliermondii

چکیده
Zearalenone, a mycotoxin produced by fungi of the genus Fusarium, including F. graminearum, triggers reproduction disorders in certain animals and hyperestrogen syndromes in humans. Current research investigates three concentrations of neem oil extract (0.1, 0.25 and 0.5%) in reducing the production of zearalenone. Neem oil extract decreased zearalenone amount in the three concentrations but highest inhibition (59.05%) occurred at 0.1%.

Evaluation of Nutrient Supplementation to Charcoal- Treated and Untreated Rice Straw Hydrolysate for Xylitol Production by Candida guilliermondii
Xylitol was produced by Candida guilliermondii from charcoal-treated and untreated rice straw hemicellulosic hydrolysate with or without nutrients (ammonium sulphate, calcium chloride, rice bran extract). Both, xylitol yield and volumetric productivity decreased significantly when the nutrients were added to treated and untreated hydrolysates. In the treated hydrolysate, the efficiency of xylos...
متن کاملNew cultive medium for bioconversion of C5 fraction from sugarcane bagasse using rice bran extract
The use of hemicellulosic hydrolysates in bioprocesses requires supplementation as to ensure the best fermentative performance of microorganisms. However, in light of conflicting data in the literature, it is necessary to establish an inexpensive and applicable medium for the development of bioprocesses. This paper evaluates the fermentative performance of Scheffersomyces (Pichia) stipitis and ...
متن کاملSugarcane straw as a feedstock for xylitol production by Candida guilliermondii FTI 20037.
Sugarcane straw has become an available lignocellulosic biomass since the progressive introduction of the non-burning harvest in Brazil. Besides keeping this biomass in the field, it can be used as a feedstock in thermochemical or biochemical conversion processes. This makes feasible its incorporation in a biorefinery, whose economic profitability could be supported by integrated production of ...
متن کاملXylitol production from wheat straw hemicellulosic hydrolysate: hydrolysate detoxification and carbon source used for inoculum preparation
Wheat straw hemicellulosic hydrolysate was used for xylitol bioproduction. The use of a xylose-containing medium to grow the inoculum did not favor the production of xylitol in the hydrolysate, which was submitted to a previous detoxification treatment with 2.5% activated charcoal for optimized removal of inhibitory compounds.
متن کاملEnhanced Xylitol Production from Statistically Optimized Fermentation of Cotton Stalk Hydrolysate by Immobilized Candida tropicalis
Cotton (Gossypium hirsutum), which is one of the most abundant crops in the world, is cultivated widely in China, the United States, and Central Asia. The cotton stalk generated with cotton cultivation is an important source of lignocellulosic biomass. In recent years, cotton stalk has received increasing attention from researchers engaged in bioconversion areas, and some high-value products, s...
