A Bifidobacterium mixed-species microarray for high resolution discrimination between intestinal bifidobacteria

A genomic DNA-based microarray was constructed containing over 6000 randomly cloned genomic fragments of approximately 1-2 kb from six mammalian intestinal Bifidobacterium spp. including B. adolescentis, B. animalis, B. bifidum, B. catenulatum, B. longum and B. pseudolongum. This Bifidobacterium Mixed-Species (BMS) microarray was used to...

The characterisation of Bacillus spores occurring in the manufacturing of (low acid) canned products

Spore-forming bacteria can be a problem in the food industry, especially in the canning industry. Spores present in ingredients or present in the processing environment severely challenge the preservation process since their thermal resistance may be very high. We therefore asked the question which bacterial spore formers are found in a typical...

Genomotyping of Pseudomonas putida strains using P. putida KT2440-based high-density DNA microarrays: Implications for transcriptomics studies

Pseudomonas putida KT2440 is the only fully sequenced P. putida strain. Thus, for transcriptomics and proteomics studies with other P. putida strains, the P. putida KT2440 genomic database serves as standard reference. The utility of KT2440 whole-genome, high-density oligonucleotide microarrays for transcriptomics studies of other Pseudomonas...

DNA based typing, identification and detection systems for food spoilage microorganisms: Development and implementation

The rapid identification of spoilage microorganisms is of eminent importance to the food industry. It provides the food industry with the opportunity to reduce economical losses by designing adequate intervention measures. The use of identification systems based on biochemical and physiological characteristics resulted often in disappointing...
