Acid chlorite delignification is frequently used to obtain a mixture of cellulose and hemicellulose known as holocellulose from biomass. While a majority of lignin is removed after holocellulose pulping, there appears to be a minor fraction of lignin

The aim of the present study was to investigate the effect of extraction conditions, mainly severity factor (H-factor = 3980–14,500) on the molecular structure of ethanol organosolv lignins extracted from Eucalyptus globulus . Isolated lignins were

Three biomass feedstocks (Loblolly pine, Sweetgum, and Miscanthus) were subjected to a novel, two-step ozone pretreatment to enhance the enzymatic digestibility of cellulose. The results show that ozone pretreatment alone did not significantly reduce

The formation of pseudo-lignin by the combination of carbohydrate and lignin degradation products has been proposed to be responsible for the increased Klason lignin content in biomass pretreated under acidic conditions. Direct evidence for the prese
