response of other algal species to photodieldrin. TABUS 5 shows that
of the algae tested, Hostoc sp. and the green alga Chlorella spporensis
appeared only slightly affected by photodieldrin at high concentration,
while A. nidulans was most inhibited. Continued growth of A. nidulans
in successive cultures in medium plus various levels of photodieldrin
did not improve initial growth rates. Other attempts to improve the organisms'
tolerance by varying growth conditions and dark incubation intervals
were unsuccessful.
