| Popis: |
Bacteria obtained from potato tubers having symptoms of soft rot and grown in different regions of Ukraine are identified as Pectobacterium carotovorum subsp. carotovorum. These bacteria strains are able to produce bacteriocines. Their killer activity in respect of P. carotovorum and Esherichia coli has been studied. The sensitivity to bactericines has been shown. Purified fractions of bacteriocines having high molecular weight (MCTV) have been obtained. The difference in composition of proteins from phage tails as compared to the ones in P. carotovorum J2 has been studied by the method of electrophoresis. It was found that the composition of MCTV major proteins of studied isolates mostly corresponds to P. carotovorum J2. The set of enzyme minor fractions has some different compositions as compared to P. carotovorum J2. It has been hypothesized that this difference is responsible for killer specificity. |
