A series of comparative physiological and morphological analyses
are described for eighteen Dendryphiella isolates. Conidial
characteristics of ten isolates showed relatively little variation as a
result of different incubation conditions. Isolates were markedly
tolerant to NaCl and KCl, although some variation between isolates was
noted. A variety of nitrogen compounds could be utilized
by most isolates although some grew poorly with certain nitrogen sources.
Most isolates showed a wide pH growth range,
particularly at alkaline values, and broad temperature growth profiles.
The relevance of these physiological characteristics to the
survival and fitness of Dendryphiella species in the marine environment
is discussed.
