Biofilm formation by Bacillus cereus was assessed using 56 strains of B. cereus, including the two sequenced strains, ATCC 14579 and ATCC 10987. Biofilm production in microtiter plates was found to be strongly dependent on incubation time, temperature, and medium, as well as the strain used, with some strains showing biofilm formation within 24 h and(More)
The advent of 'omics' techniques bears significant potential for the assessment of the microbiological stability of foods. This requires the integration of molecular data with their implication for cellular physiology. Here we performed a comparative physiological and transcriptional analysis of Bacillus subtilis stressed with three different weak organic(More)
The complete genome sequences of the lactic acid bacteria (LAB), Lactobacillus plantarum, Lactococcus lactis, and Lactobacillus johnsonii were used to compare location, sequence, organisation, and regulation of the ribosomal RNA (rrn) operons. All rrn operons of the examined LAB diverge from the origin of replication, which is compatible with their(More)
BACKGROUND Spoilage of food products is frequently caused by bacterial spores and lactic acid bacteria. Identification of these organisms by classic cultivation methods is limited by their ability to form colonies on nutrient agar plates. In this study, we adapted and optimized 16S rRNA amplicon sequencing for quantification of bacterial spores in a canned(More)
