Role of broiler carcasses and processing plant air in contamination of modified-atmosphere-packaged broiler products with psychrotrophic lactic acid bacteria

Article Abstract:

A library of HindIII restriction fragment length polymorphism (RFLP) patterns of the 16 and 23S rRNA genes as operational taxonomic units in numerical analyses were used to characterized lactic acid bacteria (LAB) isolates from broiler carcasses, production plant air, and modified-atmosphere-packaged broiler products. The results reveal that incoming broiler chickens are not major sources of psychrotrophic spoilage LAB, while the detection of these organisms from the air of the processing environment highlights the role of processing facilities as sources of LAB contamination.

Influence of lactic acid bacteria on longevity of Caenorhabditis elegans and host defense against Salmonella enterica serovar Enteritidis

Article Abstract:

The senescence of host defenses and the influence of food and nutrition on a small soil nematode, Caenorhabditis elegans are investigated. Lactic acid bacteria (LAB) enhance the host defense of the worm and prolong its lifetime.
