Chitin Synthesis -Related Proteins in the Chitin -Less Yeast Schizosaccharomyces Pombe
I identified and characterized four chitin synthesis-related proteins in S. pombe. Two of these, SpChs1p and SpChs2p are homologs of S. cerevisiae chitin synthases and two, SpChs4p and SpChs5p, are homologs of S. cerevisiae proteins that regulate, respectively, the activity and localization of …

Interactions of Chitin and Lignin Thin Films with Other Molecules
As two of the most abundant natural polymers, chitin and lignin not only play critical roles in fungal and plant cell walls but are also important functional materials and promising feedstocks for a variety of chemicals. This study investigated the interactions of chitin and lignin thin films with …

The self-assembly of chitin nanocrystals into hierarchically structured functional materials
… abundant natural resources such as a biopolymer chitin need to be better exploited. In this work, chitin was used to produce rod-shaped nanoparticles, known as chitin nanocrystals (ChNCs) via acid hydrolysis. Firstly, hydrolysis in hydrochloric acid with varied acidity (3.0 and 5.0 M) and …

Immuno-gluorescence study of five zygomycetous fungi with two chitin-binding probes
… was prepared against a purified microsomal chitinase isolated from the fungus Choanephora cucurbitarum. Indirect immunofluorescence was used to localize chitinase at various developmental stages of five zygomycetous fungi and during abiotrophic mycoparasite interaction with a susceptible and …

Investigating the Interaction of Chitin in Organic Electrolyte Solutions Using Molecular Dynamics
… liquids, similar studies have been minimal for chitin. As such, a computational investigation on the dissolution of chitin in ionic liquids and organic electrolyte solutions (OESs) is presented here. OESs consists of an ionic liquid and an additional aprotic organic molecular solvent, known …

A comparative study of in vitro chitin synthase activity in mucoraceous hosts of a mycoparasite
A comparative study of in vitro chitin synthase activity in mucoraceous hosts of a mycoparasite: Chitin synthase, the enzyme responsible for the synthesis of chitin in fungal cell wall was extracted from young hyphae of Choanephora cucurbitarum and Phascolomyces articulosus, susceptible and …

Utilization of crab processing waste and chitin associated with the waste as feed for ruminants
… Modifying the existing methods of quantifying chitin showed that initial decalcification or deprotinization of the samples with chemicals are not necessary. Similar values were obtained for chitin when ADF/ashing method was compared to the ADF/deacetylation method. These methods prevented loss …

Evaluation of Chitin as an Electron Donor and Nutrient Source for Stimulating the in Situ Bioremediation of Chlorinated Solvents
This work indicates that chitin may have several advantages over conventional, liquid electron donor injection for the in situ bioremediation of chloroethenes, and raises interesting questions on microbial community structure and motility in groundwater systems.
