JOURNAL OF FOOD SCIENCE, 78(3), M470–M476.

By: F. Breidt n, E. Medina  n, D. Wafa n, I. Perez-Diaz  n, W. Franco, H. Huang *, S. Johanningsmeier n, J. Kim *

author keywords: pickled vegetables; Pectinatus; Propionibacteria; secondary cucumber fermentation; spoilage
MeSH headings : Butyric Acid / analysis; Butyric Acid / metabolism; Cloning, Molecular; Cucumis sativus / microbiology; DNA, Bacterial / isolation & purification; Fermentation; Food Contamination / prevention & control; Food Microbiology; Hydrogen-Ion Concentration; Lactic Acid / analysis; Lactic Acid / metabolism; Pectinatus / genetics; Pectinatus / isolation & purification; Propionates / analysis; Propionates / metabolism; Propionibacterium / genetics; Propionibacterium / isolation & purification; RNA, Ribosomal, 16S / isolation & purification
TL;DR: It is reported that Propionibacterium and Pectinatus isolates from cucumber fermentation spoilage converted lactic acid to propionic acid, increasing pH, and Gram-negative anaerobic bacteria supersede Gram-positive Fermincutes species after the pH rises from around 3.2 to pH 5, and propionic and butyric acids are produced.
