Evolution of shelf life parameters of ready-to-eat escarole (Cichorium endivia var. latifolium) subjected to different cutting operations
2019
Abstract The present work was carried out to investigate the microbiological and physicochemical parameters of minimally processed escarole (Cichorium endivia var. latifolium) subjected to two different transformation processes, a classic ready-to-eat process (cut leaves, CL) and a process that excluded the cutting operation (entire leaves, EL) as control trial. Both trials were monitored during the refrigerated (4 °C) storage extended until 15 d. Total mesophilic microorganisms, total psychrotrophic microorganisms and pseudomonads were detected at the highest cell densities in all samples. The genotypic characterization of the dominating microbial populations resulted in the identification…
Occurrence of tomato pith necrosis caused by Pseudomonas marginalis in Italy.
2010
Dipartimento di Scienze e Tecnologie Fitosanitarie. Universita` degli Studi di Catania. Via Santa Sofia 100, 95123 Catania, ItalyIn 2006, a serious outbreak of tomato pith necrosis (TPN) with approxi-mately 90% disease incidence was observed in two greenhouses in Sicily.Adult fruiting plants showed chlorosis and slight wilting of shoot apices.Internalstem browning alongthe entire length oftheplant was observed.Pith tissues were soft but not rotted or hollowed. Only fluorescent colo-nies developed on King’s B medium (KB) after isolation from infected tis-sues. Ten pure isolates were all levan, oxidase, potato soft-rotting andarginine dihydrolase positive and were negative for tobacco hypersens…
