Abstract
Forty-two Pectobacterium isolates were recovered from contaminated soil and rotted vegetables in Jordan. Twenty of them were belonged to; Pectobacterium carotovorum subsp. Carotovorum (Pbc) (= Erwinia carotovora subsp. carotovora), 11 isolates were belonged to Pectobacterium atrospeticum (= Erwinia carotovora subsp. atroseptica) (Pba) and 11 isolates were not classifiable (Pbs). Maceration activity of the 42 proved their ability to macerate potato, carrot and radish slices. Maceration activity of the isolates either of the same subspecies or in between the isolates of different subspecies isolated from the same host or from different hosts was varied. The measured concentration in μM ml−1 of both cellulase and pectinase enzymes was variable too. The Rapid amplified polymorphic DNA-PCR finger printing of total genomic DNA using a pair of 10-mer oligonucleotide primers amplification showed similar DNA bands with some polymorphic variations amongst the isolates.
