NOVELTY - Cellulosic ethanol fuel generation sugar acids involves plant fiber raw material by diluted acid hydrolysis pre-treatment or diluted acid by evaporating, exploding and pre-processing, separating obtain solid material containing cellulose through solid-liquid separation, hemicellulose-containing pre-hydrolysis solution of xylose, arabinose, glucose, galactose and mannose, solid material through neutralizing, hydrolyzing the cellulose to obtain enzyme hydrolysis solution, saccharomyces cerevisiae or zymomonas mobilis anaerobic fermenting fuel ethanol production.    USE - As cellulosic ethanol fuel generation sugar acids (claimed).    ADVANTAGE - Compared with the existing technology, the cellulose fuel ethanol producing a multi-sugar acid of method by whole cell hemicellulose sugar co-catalysis production of multi-sugar product so as to drive and the raw materials in cellulose, efficient bioconversion and utilization of hemicellulose, producing the cellulose fuel ethanol; effectively improves the substrate concentration and product concentration of the raw material pre-processing liquid biological conversion, and radically up of waste water pollution in the production process, improves the economic benefit of the whole total utilization rate and production system and environmental benefit of the saccharide component in raw material for cellulose fuel ethanol in large scale industrial production.    DETAILED DESCRIPTION - Cellulosic ethanol fuel generation sugar acids involves plant fiber raw material by diluted acid hydrolysis pre-treatment or diluted acid by evaporating, exploding and pre-processing, separating obtain solid material containing cellulose is obtained through solid-liquid separation, of hemicellulose-containing pre-hydrolysis solution of xylose, arabinose, glucose, galactose and mannose, (2) solid material through neutralizing, hydrolyzing the cellulose to obtain enzyme hydrolysis solution, saccharomyces cerevisiae or zymomonas mobilis anaerobic fermenting fuel ethanol production, (3) semi-hydrolysate rear concentrating, neutralizing, using oxide gluconobacter or Pseudomonas cell under aerobic condition in co-catalytic conversion of each monosaccharide production corresponding acids product and the product comprises xylosic acid, arabic gum, glucose acid, mannitol, half milk, xylosic salt, acid salt, gluconate, mannitol sugar acids salt and semi-lactic acids.
