Inhibitory effect against pathogenic and spoilage bacteria of Pseudomonas strains isolated from spoiled and fresh fish

Article Abstract:

The antibacterial potential of Pseudomonas spp. isolated from spoiled and fresh fish were determined. The results showed that Pseudomonas spp. isolated from both spoiled iced fish and fresh fish have a broad antibacterial spectrum. Analysis of the inhibitory activity showed that it is more pronounced in siderophore-producing strains, probably through a siderophore-mediated competition for iron.

Presence of acylated homoserine lactones (AHLs) and AHL-producing bacteria in meat and potential role of AHL in spoilage of meat

Article Abstract:

Hafnia alvei was generally found to be the acylated homoserine lactones (AHLs) that produce bacterium in the study conducted. Since the distinct quorum sensing (QS) signals were added it slowed down the AHL producing Hafnia alvei to immunize the meat or to the naturally infected meat did not have any effect of the spoilage on the vacuum packed meat.

Involvement of bacterial quorum-sensing signals in spoilage of bean sprouts

Article Abstract:

A study demonstrates that the bacterial spoilage of some food products is influenced by quorum-sensing-regulated phenotypes. The understanding of these processes is believed to be useful in the development of novel food preservation additives that specially block the quorum-sensing systems.
