Abstract In this work, phosphoric acid pretreatment (0.6% H 3 PO 4 , 160 °C, 40 min) of eucalyptus residues was performed to recover the hemicellulosic fraction for further conversion l ‐lactic by fermentation with Weizmannia coagulans DSM 2314 (formerly Bacillus ). The hydrolysate composed xylosaccharides 24.8 g L –1 (mainly xylose, 20.3 ), acetic 7.8 furfural 0.7 and acid‐soluble lignin (ASL) 2.1 . It subsequently purified using anion exchange or adsorption resins. Different...
sp., a lactic acid bacterium isolated from maritime Antarctic lake, was evaluated for production lignocellulosic hydrolysate. Eucalyptus sawdust, residue pulp and paper industries, subjected to alkaline pretreatment enhance its enzymatic hydrolysis. Fermentations were performed without with pH control using eucalyptus hydrolysate containing mixture of glucose xylose sugars. The sugars successfully converted into in 24 h, resulting 7.6 g/L product yield 0.50 g/g controlled at 6.5. Fed-batch...
Butanol is an important bulk chemical and considered advanced biofuel with better properties than ethanol. It can be produced by acetone–butanol–ethanol (ABE) or isopropanol-butanol-ethanol (IBE) fermentation various Clostridium spp. In this work, eucalyptus wood pretreated in a steam explosion continuous type reactor enzymatically hydrolyzed was used as culture medium. The effect of corn steep liquor (CSL), low-cost source protein, vitamins minerals, to the enzymatic hydrolysate substitute...
