It was found, as reported in the pr vious paper, that the gradations in the reduction of TTC by filament reflected sharply the intact, injured and dead states.<br> Limits of viability of filaments under various deleterious conditions were determined by using TTC as indicator.<br> The results are summarized as fo1lows:<br> 1) Injurious effect of 10^-4M. copper sulfate in sea water becomes manifest within 1 day, 10^-6M. after 3 days, and 10^-8M. after 5 days;<br> 2) The critical temperature of causing damage after 24 hours of incubation is found at 30° to 32°C.;<br> 3) Injury becomes apparent after 3 hours of desiccation at 66% relative humidity, and within 1 to 2 hours at 10%, respectively;<br> 4) By the ultraviolet irradiation (quartz mercury sterilizing lamp), severe injury occurs after 30 minutes, and complete killing after an hour.<br> Further research in extended application of the TTC test method to other useful algae is in progress.
