Variability in structural carbohydrates, lipid composition, and cellulosic sugar production from industrial hemp varieties

Recent Advancements in Biological Conversion of Industrial Hemp for Biofuel and Value-Added Products

“…Viswanathan et al compared the hydrolysis yields from five different varieties (SC (Seward County), YC (York County), LC (Loup County), 19 m (19 m96136), and CBD (CBD Hemp)) pretreated using combined hot water and disk refining process under same operating conditions. The cellulose conversion efficiencies were observed varying from 62.3% to 85.8% [24]. Interestingly, among five different varieties, the hemp variety LC (Loup County) with maximum glucans (44.5%) had minimum sugar yields during hydrolysis (62.3%).…”

“…Table 1 summarizes the chemical composition of industrial hemp biomass in the previous studies. The chemical composition of different industrial hemp cultivars was studied [13,24,25]. Each component showed wide ranges of composition: 32.6-51.1% of cellulose, 10.6-16.6% of hemicellulose, 14.6-29.4% of lignin, 2.6-7.6% of ash, 3.7-20.0% of extractives, and 0.3-23.1% of others.…”

Viswanathan et al investigated five different hemp varieties cultivated at the same field and condition but originally from different plant locations (Seward County, York County, Loup County, 19m96136, and CBD Hemp) [24]. The authors reported that 32.6-44.5% of cellulose, 10.6-15.5% of xylan, 17.0-21.5% of lignin, 2.6-7.6% of ash, and 5.3-20.0% of extractives.…”

Advanced mono‐ and multi‐dimensional gas chromatography–mass spectrometry techniques for oxygen‐containing compound characterization in biomass and biofuel samples

“…Oleaginous biomass is mainly composed of triglycerides (TGs) containing FA carbon chains, usually in the range of C8–C22, but C16, C18, and C20 are the most common [24,25]. TGs have a high chemical energy conversion due to their very high H:C ratio and low oxygen content.…”

Effect of lignin-blocking agent on enzyme hydrolysis of acid pretreated hemp waste

“…[9][10][11] However, some recalcitrance factors, such as the crystallinity of cellulose in hemp tissues, cause technical obstacles in utilization; therefore, pretreatment is essential to remove/reduce hemicellulose and/or lignin and increase cellulose accessibility to alleviate the biomass recalcitrance factors. [12][13][14][15] Several studies have reported different pretreatment methods to improve sugar yields, including dilute acid, 10,[16][17][18][19] hydrothermalmechanical, 20 liquid hot water, 7 steam explosion, 19,21 deep eutectic solvents, 22,23 and ionic liquid. 24 The increase in sugar yield depends on the pretreatment condition and its subsequent process in cellulolytic saccharication.…”
