title: Biotype determinations for monitoring of EK1 host strains used in recombinant DNA research.
abstract: The biotypes of eight Escherichia coli K-12 strains were determined. Eight different biotypes were observed. Based upon the API biotype computer file, the appearance frequency for these K-12 biotypes ranged from 1/127 (infrequent) to 1/18,046 (rare).
