Bacteriophages 3C 13 and 3C 41 were isolated respectively from two strains of Glutamate producing bacteria that had become contaminated during an industrial fermentation.SDS PAGE showed that 3C 13 had one major band and more than eight minor bands, molecular weight of its polypeptide ranging from 28 840 to 95 000 daltons; as 3C 41 had three major bands,three minor bands and molecular weight from 17 378 to 79 433 daltons. Their nucleic acids were tested to linear ds DNA and the molecular weight of DNA ...
