The latter would provide us an integrated, systems metabolic shot about the cellulase-glycerol-ethanol fermentation. This study validated the effect of two significant factors, glucose release rate and broth viscosity identified from cellulases-assisted in-situ corn fiber conversion, on ethanol and by-...
948Bacillus polymyxa also secretes a beta amylase suitable for fermentation of starch to ethanol.2713 The amylo process involves the conversion of grains by the sequence of pressure heating, thinning the gelatinized starch with mineral acid, followed by saccharification with a mold producing diastase, ...
Conversion of corn milling fibrous co-products into ethanol by recombinant Escherichia coli strains K011 and SL40 Corn hulls and corn germ meal were both evaluated as feedstocks for production of ethanol for biofuel. Currently, these fibrous co-products are combined wi... BS Dien,RB Hespell,LO...
fermentation conditions (yeast powder as a nitrogen source; temperature of 30°C; MgSO4 as a metal ion inducer; rotation speed of 180 r/min; solid﹍iquid ratio of 1:8; and inoculation amount of 2%) resulted in an ethanol output of 46.87 g/L and a theoretical conversion rate of 27.4%...
Ethanol concentration was 7.7% (w/w) in the aqueous phase with 92% raw starch conversion. Agitation increased rate. Sacharification was the rate-limiting step. The initial ethanol concentration preventing fermentation was estimated to be 8.3% by weight. 展开 ...

(normal) maize inbreds, eight waxy and four normal inbreds were used; results are presented inTable 1. Ethanol yields obtained from the waxy maize were similar to those from the normal maize (36.0g/100g dry grain). Ethanol conversion efficiency for waxy maize (93.0%), however, was ...
