For the marine chitinoclastic bacteria isolated at Aburatsubo Inlet (Microbiological studies on the decomposition of chitin in marine environment-I), several disinfectants and chemotherapeutic agents are employed as antibacterial agents. Among the several antibacterial agents examined as disinfectants, Catiogen H (surface active agent), malachite green (dye), KMnO4 (oxidizer), and phenol (surface active agent) appeared to be suitable for killing marine chitinoclastic bacteria. As chemotherapeutic agents, though penicillin, streptomycin and sulfonamide may be suitable for shell disease of marine crustaceans caused by chitinoclastic bacteria, Kanamycin showed the highest potency for bacteriostasis at as low a concentration as 0.001 mg per ml. As for the surface active agents, Tween 80 (non-ionic) and Neogen T (anionic agent) were not observed to be toxic to the marine chitinoclastic bacteria.
