Biopreservation of Food Using Bacteriocins From Lactic Acid Bacteria: Classification, Mechanisms, and Commercial Applications

International Journal of Microbiology, Volume 2024, Issue 1, 2024.
Food is the primary substance needed by humans to survive. However, food is easily contaminated by spoilage bacteria, which cause a decrease in quality and shelf life. Moreover, spoilage bacteria in food can be pathogenic, leading to foodborne disease that endangers human health. This issue has also driven the widespread use of synthetic preservatives,

Erwinia carotovora contamination of Finnish seed potatoes and the prevalence of bacterial subspecies and serogroups

Agricultural and Food Science, 1993
Symptomless contamination with the rot-inducing bacterium Erwinia carotovora was detectable by the tuber incubation method in 82% of the commercial seed potato stocks surveyed. E. carotovora subsp. atroseptica (Eca) was more common than E.

Involvement of N-acylhomoserine Lactones Throughout Plant Infection by Erwinia carotovora subsp. atroseptica (Pectobacterium atrosepticum)

Molecular Plant-Microbe Interactions, 2004
Erwinia carotovora subsp. atroseptica is responsible for potato blackleg disease in the field and tuber soft rot during crop storage. The process leading to the disease occurs in two phases: a primary invasion step followed by a maceration step. Bacteria-

Biochemical and thermal stabilization parameters of polygalacturonase from Erwinia carotovora subsp. carotovora BR1

JOURNAL OF MICROBIOLOGY AND BIOTECHNOLOGY, 2010
With emphasis on thermal behavior in presence of different pH conditions and salts, the kinetic and thermodynamic parameters of purified polygalacturonase (PG) of E. carotovora subsp. carotovora (Ecc) BR1 were studied since characterization of an enzyme is significant in the context of burgeoning biotechnological applications.

The role of type III secretion system in Erwinia carotovora subsp. atroseptica virulence

Plant Protection Science, 2002
A hrpJ mutant of Erwinia carotovora subsp. atroseptica (Eca) was constructed and the effects of this mutation on induction of the hypersensitivity response and virulence of Eca were studied.

Characterization of a Novel Pectate Lyase fromErwinia carotovorasubsp.carotovora

Molecular Plant-Microbe Interactions, 1995
The pectate lyase (Pel, EC 4.2.2.2) isoenzyme profile of Erwinia carotovora subsp. carotovora was characterized by isoelectric focusing, and the corresponding genes coding for four different exported Pels were cloned. The nucleotide sequence of the pelB gene encoding one of these isoenzymes was determined and was shown to contain 1,040-bp open reading ...

Molecular Characterization and Expression of the Erwinia carotovora hrpNEcc Gene, Which Encodes an Elicitor of the Hypersensitive Reaction

Molecular Plant-Microbe Interactions, 1997
The nucleotide sequence of hrpNEcc DNA, cloned from Erwinia carotovora subsp. carotovora strain Ecc71, reveals a coding region of 1,068 bp which matches the size of hrpNEcc transcripts.

Cloning and Sequencing of the celA Gene Encoding CMCase of Erwinia carotovora subsp. carotovora LY34

Molecules and Cells, 1998
The phytopathogenic Erwinia carotovora subsp. carotovora LY34 secretes multiple isozymes of the plant cell wall-disintegrating enzyme, endoglucanases. Genomic DNA from Ecc LY34 was digested with Sau3AI and ligated into the BamHI site of pBluescript II SK+. One of the E.

A Potato Gene Encoding a WRKY-like Transcription Factor Is Induced in Interactions with Erwinia carotovora subsp. atroseptica and Phytophthora infestans and Is Coregulated with Class I Endochitinase Expression

Molecular Plant-Microbe Interactions, 2000
A potato gene encoding a putative WRKY protein was isolated from a cDNA library enriched by suppression subtractive hybridization for sequences upregulated 1 h post-inoculation with Erwinia carotovora subsp. atroseptica.
