ABSTRACT:
A culture medium composed of necessary sources and tap water is sterilized, inoculated under strains of the genus Streptococcus and then cultivated under aeration and agitation. Subsequent to the cultivation, the resultant was subjected to water-washing and sieving to obtain crude glucan. The crude glucan is then dissolved in NaOH solution and centrifuged. The recovered filtrate is neutralized with HCl and then the insolubilized glucan was collected by centrifugation. After repetition of the procedures, the collected glucan is washed with water thoroughly until no chloride ion is detected in the waste water and then dried to form white purified glucan powder.
