Acid hydrolysis of sunflower residue biomass

Synthesis of Sugars by Hydrolysis of Hemicelluloses- A Review

“…Corn stover is a waste that contains on average about 20% xylan and 3% arabinan, whereas its cellulose and lignin contents are only about 35% and 17%, respectively . Sunflower stalk is also a waste formed during the sunflower seed production, and it contains cellulose, hemicelluloses, and lignin at about 38%, 30%, and 11%, respectively . Typically the stalk to seed weight ratio is about 2.3 .…”

“…The acid hydrolysis of biomass for production of sugars has been studied intensively for 100 years. ,− …”

The effects of boron derivatives as pretreatment chemicals for biodegradation of sunflower stalks

“…In this context, the effects of physicochemical pretreatments like hydrothermal (Diaz et al 2011, Eom andYu 2015) and steam explosion (Ruiz et al 2008, Sharma et al 2002, and of chemical pretreatments like alkali (Soto et al 1994), hydrochloric acid (Bonilla et al 1990), sulfuric acid (Jimenez and Bonilla 1993, Tosun 1997, Ruiz et al 2013) and peracetic acid (Farid et al 1983) have been studied for sunflower stalks. Additionally, Sharma et al (2002) and Ruiz et al (2006) have examined the fermentation and ethanol production from sunflower stalks.…”

Reducing Sugar-Producing Bacteria from Guts of Tenebrio Molitor Linnaeus (Yellow mealworm) for Lignocellulosic Waste Minimization

“…Chemical, mechanical, and enzymatic approaches have been used in the hydrolysis of lignocellulose (i.e., consisting of cellulose, hemicellulose and lignin) to release primarily hexose and pentose sugars for subsequent fermentation to ethanol, lactic acid and xylitol (19,23); however, some drawbacks of these conventional approaches (e.g., inhibition by acid of the subsequent bioprocess, and the high cost of the enzyme) (7,17,22,25) have attracted the attention of scientists. Alternatively, recent studies on microbial degradation of large molecules, such as cellulose, hemicellulose, and lignin, have suggested that bioconversion is a possible treatment of lignocellulosic waste (3,9,11).…”
