text: [Numerical taxonomy of fifty two strains Streptomyces by whole-cell protein composition].
  By using SDS-PAGE, fifty two strains Streptomyces were analysed for whole-cell protein composition. Electrophore pattern was divided into fifty composition for numerical taxonomy. The clustering result indicate that all strain's similarity is over 72 percent and different strains in a species is over 84 percent. The most similar strains is 96 percent.
