Latilactobacillus sakei is the type species of the genus Latilactobacillus that was previously classified in the genus Lactobacillus. [1] It is homofermentative; hexoses are metabolized via Glycolysis to lactic acid as main metabolite; pentoses are fermented via the Phosphoketolase pathway to lactic and acetic acids. [2]

Uses

Antilisterial strains of L. sakei are used in Europe for the production of saucisson and can be used for the conservation of fresh meat.[3]

L. sakei strains isolated from traditional dry sausage have a potential use as starter cultures.[4]

Inhibition of Listeria monocytogenes in chicken cold cuts can be obtained by addition of sakacin P and sakacin P-producing Lactobacillus sakei.[5]

Strain 2a of the subspecies L. sakei subsp. sakei can also be isolated from meat products.[6]

Research suggests that L. sakei may play a role in maintaining healthy sinus cavities and preventing sinusitis.[7]

Biochemistry

Bacteriocins production

Sakacins are bacteriocins of class II produced by L. sakei.

In strain CCUG 42687, their production is dependent on nutrients, temperature and pH.[8] Using the same strain, sakacin P can be produced in a completely defined medium.[9]

In strain CTC 494, the presence of salt and a curing agent (sodium chloride and sodium nitrite) reduces the production of the antilisterial bacteriocin sakacin K.[10] Growth of CTC 494 is also dependent on nutrients availability.[11]

Lactocin S is a bacteriocin produced by strain L45 of Lactobacillus sakei.[12]

Exopolysaccharide biosynthesis

Strain 0–1 of L. sakei produces exopolysaccharides.[13]

Prevention

Eugenol is a chemical compound that can be used to reduce the presence of L. sakei[14] as it disrupts its cellular membranes.[15]

Genetics

Genetic diversity within L. sakei has been assessed through the use of specifically designed PCR primers for detection using randomly amplified polymorphic DNA, [16] or by multi-locus sequence typing. [17]

Bacteriocin genes

Bacteriocin genes are located either on chromosomes or on plasmids. Strain 5 produces a plasmid-encoded bacteriocin that is identical to sakacin P, as well as two chromosomally encoded bacteriocins, which were designated sakacin T and sakacin X.[18]

LasX is a transcriptional regulator of the lactocin S biosynthetic genes in strain L45 of Lactobacillus sakei.[19]

Other genes

In strain LTH677, a starter organism used in meat fermentation, there is an oxygen-dependent regulation of the expression of the catalase gene katA.[20]

In strain LTH681, the stress operon dnaK has been characterized in 1999 as a heat shock protein gene.[21]

There is only one gene (IdhL) responsible for the lactic fermentation.[22]

Plasmids

A Theta-type plasmid has been characterized in Lactobacillus sakei in 2003. It is a potential basis for Low-Copy-Number vectors in lactobacilli.[23]

Vectors for inducible gene expression in L. sakei can be constructed. The key elements of these vectors are a regulatable promoter involved in the production of the bacteriocins sakacin A and sakacin P and the genes encoding the cognate histidine protein kinase and response regulator that are necessary to activate this promoter upon induction by a peptide pheromone.[24][25]

Genome

The genome of the meat-borne lactic acid bacterium Lactobacillus sakei 23K has been published in 2005.[26]

It is composed of 1884661 nucleotides forming 1879 protein genes and 84 RNA genes.[27]
