Brewers' spent grain : generation, characteristics and potential applications
Brewers' spent grain (BSG) is the major by-product of the brewing industry, representing around 85% of the total by-products generated. BSG is a lignocellulosic material containing about 17%…
Alternatives for detoxification of diluted-acid lignocellulosic hydrolyzates for use in fermentative processes: a review.
The effects of the inhibitory compounds on fermentation yield and productivity, as well as various detoxification methods for treating the hydrolyzates are described.
A study on chemical constituents and sugars extraction from spent coffee grounds
Spent coffee grounds (SCG), the residual materials obtained during the processing of raw coffee powder to prepare instant coffee, are the main coffee industry residues. In the present work, this…

Some current and promising technologies for ethanol production are reviewed considering aspects related to the raw materials, processes, and engineered strains development.
Effect of hemicellulose and lignin on enzymatic hydrolysis of cellulose from brewer's spent grain
Abstract Enzymatic hydrolysis of brewer's spent grain in three different forms: original (untreated), pretreated by dilute acid (cellulignin), and pretreated by a sequence of dilute acid and dilute…
Chemical characterization and liberation of pentose sugars from brewer's spent grain
The chemical composition of brewer's spent grain (BSG), generated from a process using 100% malted barley, was investigated. BSG is mainly composed of (g kg−1) hemicellulose (284), lignin (278),…
Ferulic and p-coumaric acids extraction by alkaline hydrolysis of brewer's spent grain
Abstract This work deals with the alkaline hydrolysis of brewer's spent grain (BSG) for the extraction of ferulic and p-coumaric acids, compounds of considerable interest for applications in the…
Dilute-acid hydrolysis for optimization of xylose recovery from rice straw in a semi-pilot reactor
Abstract Rice straw is composed of pentose that can be used as a raw material for the production of many types of useful compounds. One of these is xylitol, with a potential application in the food…
Effects of medium supplementation and pH control on lactic acid production from brewer's spent grain
Abstract A cellulose pulp obtained by chemical pre-treatment of brewer's spent grain was saccharified by a commercial cellulase preparation and the produced hydrolysate (50 g/l glucose) was fermented…
Acid hydrolysis and fermentation of brewer's spent grain to produce xylitol
The hemicellulosic fraction of brewer's spent grain (BSG) was hydrolysed with diluted acid under different conditions of liquid/solid ratio (8–12 g g−1), sulfuric acid concentration (100–140 mg g−1…
