N-acetylglucosamine (NAG) is the monomer product of chitin, which has been widely used as a bioactive com- pound in applications such as anti-tumor, anti-microbial, and antioxidant activities. In production, biological processes using enzymes are preferab... see more

Chitin là m?t polysaccharide t? nhiên r?t phong phú và du?c ?ng d?ng nhi?u trong các linh v?c, d?c bi?t là trong b?o qu?n th?c ph?m và y du?c. M?c dích c?a nghiên c?u này nh?m xác d?nh di?u ki?n kh? khoáng và kh? protein trong quy trình s?n xu?t chitin b?... see more

Chitinase is enzyme that hydrolyzes chitin, a polimer of b-1,4-N-Acetilglucosamine which is the most abundant natural resource after cellulose. Chitinolytic microorganism can be found in  environment like soil and water that contain chitin, or in ext... see more

Chitinase is an extracellular enzyme which is capable in hydrolyzing insoluble chitin to its oligomeric and monomeric components. The enzyme produced by thermophilic bacteria was screened and isolated from Sulili hot spring in Pinrang, South Sulawesi, Ind... see more

Study of chitosan prepared with chitin deacetylation by multistage alkali treatments has been done. Chitin was extracted from Lampung white shrimp's (Litophenaeus vannamei) shell. The FTIR spectroscopy was used to determine deacetylation degree of chitin/... see more

This study reports the results of the elucidation of the sorption-desorption mechanism of Zn(II) and Cd(II) on chitin through the determination of capacity, energy, and rate constant of sorption as well as the investigation of their desorption properties ... see more

Immobilization of humic acid on chitin has been conducted and applied to the adsorption of Cr(III). The humic acid was isolated using NaOH 0.1 M, while chitin was isolated by deproteination of crab shells by using NaOH 3.5 % (w/v) and followed by deminera... see more

Partially deacetylated a-chitin nanofibers/nanowhiskers mixtures (DEChNs) were prepared by 35% sodium hydroxide (NaOH) treatment followed by disintegration in water at pH 3–4. The aim of this study was to investigate the hypolipidemic effects of DEChNs at... see more

Thermophilic bacteria producing chitinase were collected from Prataan hot spring, East Java, Indonesia and screened. The isolated bacterium was analyzed using 16S rRNA gene sequencing analysis and identified as Paenibacillus sp. The molecular identificati... see more
