Morphological spore types in the Streptomyces hygroscopicus-like complex.
Streptomycetes comprising the Streptomyces hygroscopicus-like complex may be divided into two groups based on the micromorphology of their spores. The species S. hygroscopicus has short-cylindrical, phalangiform spores, whereas members of the second group possess elliptical-type spores. It was determined that S. platensis, of the latter group, is not only readily distinguishable from S. hygroscopicus on the basis of spore micromorphology, but differs, as well, according to various physiological measurements.
