| Summary: | Chitosan that was isolated from horseshoe crabs, Tachypleus gigas, for this study were
from estuary area in Balok Pahang (East coast) and Muar Johor (West coast) of the Malay
Peninsula. The isolation of chitosan was carried out by chemical processes involving
deproteinization, demineralization and deacetylation. Physicochemical properties and antibacterial
activity were analysed to determine its potential commercialization. The degree of deacetylation
(DD) was higher for samples from Balok than Muar (42.4% and 35.2% respectively), but lesser
than the commercial grade. There was no significant difference (p>0.05) in the physicochemical
properties but obviously they had lesser moist (1.11±0.22 - 1.25±0.13%), higher ash content
(1.99±0.06 - 2.37±0.07%), and low in its solubility (58.00±9.63 - 61.70±1.35%) as well as viscosity
(52.52±5.38 - 64.37±4.73 cP) if compared with commercial chitosan. Chitosan from both field
sites also showed great antibacterial activities which concentration dependent against
Staphylococcus aureus and Eschericia coli. |
