Abstract:	The main purpose of this research was to investigate the antitumor and antimicrobial activities of the chitooligosaccharides containing hydrolyzates obtained from the hydrolysis of chitinous materials (such as chitin, chitosan, and squid pen) by bromelain. The optimum preparations were gained in the hydrolysates of squid pen powder hydrolyzed at pH5, 37.degree.C for 2 days by 0.1% bromelain. The hydrolysates had an 80% inhibitory activity on Fusarium oxysporum. Chitooligosaccharides were recovered from the hydrolysates and were used for tumor cell surviving test. Surviving rate of the human leukemic U937 cells was reduced to 69% by the chitooligosaccharides.
