Flavobacterium sp. ATCC 27551 is prototrophic, streptomycin‐resistant and contains plasmid DNA. Two strains of this Flavobacterium sp. with altered growth requirements and antibiotic sensitivity have been isolated. Unlike the parental strain, both isolates are sensitive to the antibiotic streptomycin. Isolate YE requires yeast extract supplementation of the medium and contains no plasmid DNA. Isolate AHC contains plasmid DNA and requires aspartic acid, histidine and cysteine for growth.
