The Electrophoretic Movement of Proteins from Various Streptomyces Species as a Taxonomic Criterion Gottlieb, D. and Hepden, Pamela M.,, 44, 95-104 (1966), doi = https://doi.org/10.1099/00221287-44-1-95, publicationName = Microbiology Society, issn = 1350-0872, abstract= Summary: Attempts have been made to use the protein composition of streptomycetes as a criterion in their classification. By using polyacrylamide gel electrophoresis, negatively charged proteins in extracts of various streptomycete strains were separated. For each strain a distinctive pattern of protein bands was obtained. Protein bands were mapped for a number of strains, including several each of Streptomyces venezuelae and S. griseus. Maps were compared and contrasted: in general there was more similarity between strains within one species than between strains of different species. Although the polyacrylamide gel technique cannot yet be used as a major criterion in classification, it can serve, in conjunction with other criteria, as an aid in streptomycete taxonomy., language=, type=
