The Effect of Thermal Processing Schedules and Unit Operations on the Quality of Blue Crab (Callinectes sapidus) Meat
… for the destruction of microorganisms, including Listeria monocytogenes. F-values calculated indicated a sufficient reduction of L. monocytogenes at each processing time. Fresh picked crab meat was evaluated for microbial levels when exposed to ambient temperatures over a four hour period. It was …

Esterase 2-oligodeoxynucleotide conjugates as enzyme reporter for electrochemical detection of DNA and identification of bacterial species
… 16S rRNA was demonstrated. Escherichia coli and Listeria innocua were easily identified as judged by signals given by rRNA hybridization with species-specific capture ODNs. This system allows a detection of 1,000 Escherichia coli cells. As a further optimization, a stem-loop structured molecular …
