|
|
|
A method for lab scale production and isolation of chitosan from mycelia of Cunninghamella blakesleeana IFO 4443 mutant was developed. Mutant of Cunninghamella blakesleeana IFO 4443-10 obtained by UV radiation was cultivated in 5L jar fermentor at 30℃ for 3days. The fungus were grown well at pH 4.5. Chitosan was readily extracted from mycelia walls with alkali treatment. The maximum yield of chitosan obtained was 1012㎎/L and degree of deacetylation was 84.6%.
