pubmed:abstractText |
A number of A. chrysogenum strains from a lineage improved in cephalosporin C production were analysed by contoured-clamped homogeneous electric field gel electrophoresis (CHEF). Although antibiotic titre was increased across the lineage, chromosome rearrangements were only observed at two points in it. In one member of the lineage the chromosomal changes included those which altered the size of the chromosome on which the isopenicillin N synthetase gene (pcbC) was located. It is proposed that chromosome changes are a chance event in an industrial strain improvement programme.
