Enzymatic accessibility of fiber hemp is enhanced by enzymatic or chemical removal of pectin

Thermochemical pretreatments for enhancing succinic acid production from industrial hemp (Cannabis sativa L.)

“…1c), whereas lower losses were observed when H 2 O 2 was used as catalyst. Simultaneous losses of hemicellulose and lignin, during alkali pretreatment of hemp, have also been previously observed (Pakarinen et al, 2012). Such losses constitute a major drawback of alkali pretreatments.…”

Omega-3 fatty acid production from enzyme saccharified hemp hydrolysate using a novel marine thraustochytrid strain

“…Hemp stalks are used for industrial purpose due to the higher volume of stalk (two times higher) than bast fibre. Interest in the use of hemp biomass is due to its high cellulose content (cellulose ~55%, hemi-cellulose ~16%, pectin ~18% and lignin ~4%) (Jaldon et al, 1998), easier availability, high biomass yield, low need of fertilization and insensitivity to frost (Pakarinen et al, 2012;Abraham et al, 2013). Hemp has been used as a potential biomass for the production of bioenergy such as ethanol, biogas, electricity and methane (Barta et al, 2013).…”

“…LCB consists mainly of lignin, cellulose and hemicellulose that requires pretreatment for the opening of the compact structure by breaking cross-linked bonds Cao et al, 2013). Pretreatment increases the hydrolysability of complex materials and maximizes enzyme penetration by increasing the cellulose surface area, thus producing sugar hydrolysate (SH) that can be used for producing ethanol and lipids (Pakarinen et al, 2012;Abraham et al, 2014). Reducing sugars such as glucose, xylose, mannose, arabinose, glucan, rhamnose, and cellobiose are the main constituents in the sugar hydrolysate and their concentration vary based on the biomass composition (Toquero and Bolado, 2014).…”

Preliminary investigations on a polygalacturonase from Aspergillus fumigatus in Chinese Pu’er tea fermentation

“…A polygalacturonase from Saccharomyces cerevisiae isolated from marsh grape fruit pulp possessed the maximal activity at 45°C [19]. As well known, high temperatures of 50-60°C are potentially useful for application in the fabric industry to separate cotton fabrics and polish enzymes, in the paper industry to remedy the retention problems in mechanical pulp bleaching, and in the food industry to clarify juice [20,21]. Therefore, thermostable pectinases are highly demanded in these modern industries.…”
