A.,, 5, 926-929 (1951), doi = https://doi.org/10.1099/00221287-5-5-926, publicationName = Microbiology Society, issn = 1350-0872, abstract= Summary: The zygospores of several species of Chlamydomonas present in dry soil are very resistant to dehydrating agents. Based on this resistance a method for the isolation of sexual strains has been developed, and two homothallic and three heterothallic species of Chlamydomonas have been obtained in pure culture., language=, type=
