Synthesis of Biotin-Tagged Chitosan Oligosaccharides and Assessment of Their Immunomodulatory Activity

Frontiers in Chemistry, 2020
Chitin, a polymer of β-(1→4)-linked N-acetyl-d-glucosamine, is one of the main polysaccharide components of the fungal cell wall. Its N-deacetylated form, chitosan, is enzymatically produced in the cell wall by chitin deacetylases.

Identification and Enzymatic Properties of Chitosanase Producing Marine Paenibacillus chitinolyticus Strain CLT08

Shipin gongye ke-ji, 2022
At present, chitosanase used to prepare chito-oligosaccharides has the disadvantage of low enzyme activity and poor acid stability. In this study, chitosanase-producing strain was screened from mud samples from Lianyungang Haizhou Bay, the highest ...

Dual Role of Chitin as the Double Edged Sword in Controlling the NLRP3 Inflammasome Driven Gastrointestinal and Gynaecological Tumours

Marine Drugs, 2022
The role of NLRP3 in the tumour microenvironment is elusive. In some cancers, the activation of NLRP3 causes a worse prognosis and in some cancers, NLRP3 increases chances of survivability.

Efficient chito-oligosaccharide utilization requires two TonB-dependent transporters and one hexosaminidase in Cellvibrio japonicus

, 2021
Chitin utilization by microbes plays a significant role in biosphere carbon and nitrogen cycling, and studying the microbial approaches used to degrade chitin will facilitate our understanding of bacterial strategies to degrade a broad range of ...

Feeding Marine Polysaccharides to Alleviate the Negative Effects Associated with Weaning in Pigs

Animals, 2021
In young pigs, the challenge of weaning frequently leads to dysbiosis. This predisposes pigs to intestinal infection such as post-weaning diarrhoea (PWD).

Short chain chito-oligosaccharides promote arbuscular mycorrhizal colonization in Medicago truncatula [PDF]

Carbohydrate Polymers, 2020
During the establishment of arbuscular mycorrhizal (AM) symbiosis, the fungus and the host plant exchange chemical signals that are crucial to reciprocal recognition. Short-chain chitin oligomers (CO) released by AM fungi are known to trigger symbiotic signaling in all host plant species tested.

From Synthesis to Therapeutics: Bioactive-Coated Zein Nanoparticles in Drug Delivery. [PDF]

Biopolymers
ABSTRACT Polymeric zein nanoparticles (ZNP), derived from corn protein, are biodegradable drug carriers with high stability and low synthesis costs. Their amphiphilic nature allows efficient encapsulation of both hydrophilic and lipophilic drugs, making them promising for drug delivery.

Impact of Lipo-Chito-Oligosaccharides (LCO) as Foliar Spray on Soybean (Glycine max (L.) Merr.) Yield

Madras Agricultural Journal, 2015
The bacterium to plant signal, lipo-chito-oligosaccharides (LCOs) or Nod factors induce cell division and enhance plant growth. In the present study LCO has been applied through foliar spray at two different stages (V 2 ), 20-25 DAS and 40-45 DAS (V 4 ).
