peptides with antibiotic activity.
    (b) The ingredient is a concentrate or dry material that meets the 
specifications that follow when it is tested as described in 
``Specifications for Identity and Purity of Some Antibiotics,'' World 
Health Organization, FAO Nutrition Meeting Report Series, No. 45A, 1969, 
which is incorporated by reference. Copies are available from the
