“…Graft copolymers differ in properties, hence also in applications, which include drug deliverer systems, plastics, textiles and many more. Polysaccharide based graft copolymers can replace some chemically synthesized graft copolymers (Bond and Bolt, 1989;Gürdag and Sarmad, 2013;Meshram et al, 2009;Thakur and Thakur, 2014). A very recent study exploited SthAbf62A-m2,3 in combination with BaAbf43B-d3 to produce unsubstituted WAX, which increased the yield and influenced the viscoelastic properties of grafted xylans, which can be used as biobased coatings on cellulose (Littunen et al, 2017).…”

Motivated by industrial demands and ongoing scientific discoveries continuous efforts are made to identify and create improved biocatalysts dedicated to plant biomass conversion. --1,3 arabinofuranosyl specific -L-arabinofuranosidases (EC 3.2.1.55) are debranching enzymes catalyzing hydrolytic release -L-arabinofuranosyl residues, which decorate xylan or arabinan backbones in lignocellulosic and pectin constituents of plant cell walls. The CAZy database classifies -L-arabinofuranosidases in Glycoside Hydrolase (GH) families GH2, GH3, GH43, GH51, GH54 and GH62. Only GH62 contains exclusively -L-arabinofuranosidases and these are of fungal and bacterial origin. Twenty-two GH62 enzymes out of 223 entries in the CAZy database have been characterized and very recently new knowledge was acquired with regard to crystal structures, substrate specificities, and phylogenetics, which overall provides novel insights into structure/function relationships of GH62. Overall GH62 -L-arabinofuranosidases are believed to play important roles in nature by acting in synergy with several cell wall degrading enzymes and members of GH62 represent promising candidates for biotechnological improvements of biofuel production and in various biorefinery applications.3

“…Redox initiators like Fenton's reagent, potassium persulfate, and cerium (IV) ammonium nitrate (CAN) have been found to be effective for this purpose [5][6]. Although maleic acid is not an ordinary vinyl monomer, it has been reported to polymerize in water in the presence of potassium persulfate and poly (N-vinyl pyrrolidinone) [7]. The graft copolymer is an effective superabsorbent resin (SAR) and can absorb water 704 times its own dry weight [8].…”

Chitosan (CS) was successfully grafted with maleic acid (MA) in 1% acetic acid solution by using potassium persulfate (KPS) as the initiator. The grafting yield (GY) up to 84.25 % and grafting efficiency (GE) of 64.82 % were achieved. The formation of grafted chitosan was confirmed with usual spectroscopic methods and thermal analysis. The raw grafted chitosan was mixed with Na + , Mg 2+ and Ca 2+ in aqueous hydroxide solution and K + in aqueous chromate solution. The reaction mixtures were separated from excess unreacted maleic acid and characterized as a reacted grafted chitosan. The results showed a new form of maleic grafted chitosan after the reaction with metals. Also, grafted of CS with MA provide a promising set of materials for potential slow release fertilizer applications.

“…Though synthetic adhesives have advantage in performance parameter, they have drawbacks like high formaldehyde emission, finding alternate resources for raw material is the only solution for increasing scarcity of petroleum resources, the mainly used raw materials of wood adhesives is being replaced by renewable biopolymers, such as soybean protein [6] [7] [8], natural tannin [9] [10] [11] and starch [12]. Starch is a kind of renewable, biodegradable, inexpensive, and readily available biopolymer extensively used as binders, glues, and pastes [13]- [20]. In all biopolymers stated above starch is easily available and low cost, many studies have been carried out which has given comparable results.…”

Increasing global energy crisis and scarcity of petroleum resources has shifted focus of chemical industries to look for alternative raw material resources. The main focus of raw materials in wood adhesives, such as petroleum and natural gas [1] [2], would be gradually replaced by renewable biopolymers. Starch is a relatively inexpensive and renewable product from abundant plants, easy processing and it has been extensively used as binders, sizing materials, glues and pastes [3], but its bonding capacity is not strong enough to glue wood [4]. Extensive research has been carried out on improving the cohesive properties, especially water resistance, of starch-based adhesives. In starch-based wood adhesive many new approaches have come forward for effective use it in wood/wood composite adhesive giving comparable performance as synthetic adhesives. This review of starch-based adhesives is made with the focus on starch modification methods for improving properties of starch-based adhesives.
