“…The best study of the requirements for a minimal medium leading to normal growth is that of 0degird (133). The nitrogen source may be either inorganic (ammonium tartrate, ammonium citrate) or organic (asparagine), although the latter gives generally better growth.…”

“…Cultures responded identically to the two thiamine levels, and so the results were pooled without regard for thiamine content for display in this paper. Cultures of strain 8743a employed 20-ml aliquots of a 1:1 mixture of solutions A and C, to give the mineral content recommended by Odegard (6). Thiamine was supplied at 0.0173 ,ug/ml and asparagine at 58 or 2.33 ,ug/ml.…”

The influence of light on asexual fruiting and mycelial growth of Phycomyces blakesleeanus Burgeff was studied by means of fruiting body counts and size measurements in cultures on solid media under varied incubation conditions. Five types of photoresponses were shown by ATCC Strain 8743a: (a) photoinduction of giant sporangiophores; (b) The same photosystem that modifies fruiting in P. blakesleeanus may also be at work in other members of the Mucorales; comparable responses in various genera (see "Discussion") have long been known but have not been explored in depth. A perhaps related photocontrol of metabolism and sporulation occurs in Blastocladiella (4,8). and many instances of light-controlled fruiting are known among the higher fungi (4).A chief objective in this study has been to define circumstances under which the mycelial photoresponses can be observed. Therefore, the modifying effects of ambient temperature and nitrogen nutrition are described in relation to several of the responses. As a check on generality of the photoresponses, two morphologically identical strains of P. blakesleeanus from different culture collections have been studied in parallel. These strains differed in several aspects of light sensitivity as indicated in the following text.The photoinduction of giant sporangiophores has been given special attention as a model system for estimating the spectral sensitivity and minimal light dose requirements of the mycelium. These data suggest that the same photoreceptor system operates in the mycelium as in sporangiophores.
