Abstract
Soluble cell protein and lipopolysaccharide (LPS) profiles in SDS-PAGE of non-icenucleation active (non-INA) Pseudomonas fluorescens strains with antagonistic activityagainst ice nucleation-active (INA) bacteria were evaluated as approaches for theirmonitoring when released for biological control. The strains examined had differentprotein profiles, with similarity coefficient ranging from 25 to 58%, useful for theiridentification. These profile were markedly different from those obtained from two P.fluorescens INA strains and a P. syringae INA strain analysed for comparison.Antagonistic non-INA P. fluorescens strains showed smooth-type LPS profiles, whereassemi-rough type LPS profiles were observed in INA Pseudomonas strains.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
