Book ChapterDOI
Enzyme Engineering for Oligosaccharide Biosynthesis
TL;DR: This chapter provides an overview about the facts and potentials of oligosaccharide production methodologies, making special emphasis on the enzymatic-based technology, which shows clear advantages over chemical methods.
Journal ArticleDOI
Chitooligomers inhibit UV-A-induced photoaging of skin by regulating TGF-β/Smad signaling cascade
TL;DR: It is suggested that chitooligomers can be developed as topical application of natural anti-aging cosmeceuticals since reduced the skin collagen decomposition by enhancement of collagen synthesis.

Effects of chitosan oligosaccharides addition to Japanese quail's diets on growth, carcass traits, liver and intestinal histology, and intestinal microflora.
TL;DR: In conclusion, the addition of 75 mg/ kg of COS had no adverse effect on the tested parameters, and it increased the crypt depth, villus length, and beneficially on intestinal microflora.

Food applications of chitin and chitosans
TL;DR: Application of chitinous products in foods and pharmaceuticals as well as processing aids has received considerable attention in recent years as exotic synthetic compounds are losing their appeal.
Journal ArticleDOI
Antibacterial action of chitosan
TL;DR: Fungal chitosan had significantly less antibiotic effect than CH and CL, and was shown to be concentration dependent with 0.1 mg/mL more effective than 2.0 and 5.0 mg/ mL.
Journal ArticleDOI
Chitosan: A Unique Polysaccharide for Drug Delivery
TL;DR: The aim of this review is to give an insight into the many potential applications of chitosan as a pharmaceutical drug carrier.
BookDOI
Chitin in nature and technology
TL;DR: Chitin has been a landmark for polysaccharides and modified chitins, besides chitin itself, to the point that three International Conferences on Chitin / Chitosan were convened (Boston, U.S. A. 1977, Sapporo, Japan 1982 and Senigallia, Italy 1985).
Journal ArticleDOI
Antimicrobial effect of chitooligosaccharides produced by bioreactor
TL;DR: In this paper, the antibacterial effect of three kinds of chitooligosaccharides with relatively higher molecular weights (HMWCOS), medium molecular weight (MMWCOS), and lower molecular weight, respectively, was evaluated against various microorganisms.
