Abstract
Two methods were used to produce chitosan by deacetylation of chitin
which was extracted from
Agaricus bisporus stipes. The first one gives chitosan 1
with low yield of 2.5%, degree of acetylation (DA) of 4%, molecular weight
(MW) of 2.973 × 10
5 (g/mol). The second route produces chitosan 2 with higher
yield of 41%, degree of acetylation (DA) of 17.23%, molecular weight (MW) of
2.939 × 10
5 (g/mol). Both chitosans were characterized by XRD, FTIR,
1
H-NMR
spectroscopy nuclear magnetic resonance of proton. The molecular weight (M
W)
was determined by size exclusion chromatography (SEC). Thermal analysis
shows that both chitosans have moisture content lower than 10%. However chitosan 2 has the less ash % which is the quality grade for chitosan medical applications. Accordingly, fungal chitosan 2 could have potential medical and
agricultural applications.
