SOME GROWTH PROPERTIES
OF HAPLOID AND DIPLOID STRAINS OF
PROTOMYCES INUNDATUS
M. Salih

Abstract: The fungus
Protomyces inundatus
Dangeard grows readily in liquid culture, budding in a yeast like
fashion. Glucose saturation constant is 0.45 X 10-5M, while
the maximum exponential growth rate is 0.136 divisions per hour. T
liamine is required for g -owth and it can not be replaced with
pyrimidine or thiazole moieties when present in the medium alone or
simultaneously. This fungus can utilize a number of nitrogen or carbon
sources. No differences are found in the haploid and diploid strains for
the growth properties studied. The differences in the behaviour of
nucleic acids in haploid and diploid strains are discussed in the light
of this new investigation.
