چکیده

Lactococcus lactis subsp. lactis strains show glutamate decarboxylase activity, whereas L. lactis subsp. cremoris strains do not. The gadB gene encoding glutamate decarboxylase was detected in the L. lactis subsp. cremoris genome but was poorly expressed. Sequence analysis showed that the gene is inactivated by the frameshift mutation and encoded in a nonfunctional protein.

Rapid PCR-based method which can determine both phenotype and genotype of Lactococcus lactis subspecies.

A highly efficient, rapid, and reliable PCR-based method for distinguishing Lactococcus lactis subspecies (L. lactis subsp. lactis and L. lactis subsp. cremoris) is described. Primers complementary to positions in the glutamate decarboxylase gene have been constructed. PCR analysis with extracted DNA or with cells of different L. lactis strains resulted in specific fragments. The length polymor...

Diacetyl and a-Acetolactate Overproduction by Lactococcus lactis subsp. lactis Biovar Diacetylactis Mutants That Are Deficient in a-Acetolactate Decarboxylase and Have a Low Lactate Dehydrogenase Activity

Lactococcus lactis subsp. lactis biovar diacetylactis strains are utilized in several industrial processes for producing the flavoring compound diacetyl or its precursor a-acetolactate. Using random mutagenesis with nitrosoguanidine, we selected mutants that were deficient in a-acetolactate decarboxylase and had low lactate dehydrogenase activity. The mutants produced large amounts of a-acetola...

The gene encoding the glutamate dehydrogenase in Lactococcus lactis is part of a remnant Tn3 transposon carried by a large plasmid.

The gene responsible for the uncommon glutamate dehydrogenase (GDH) activity of Lactococcus lactis was identified and characterized. It encodes a GDH of family I that is mainly active in glutamate biosynthesis, is carried by a large plasmid, and is included, with functional cadmium resistance genes, in a remnant Tn3-like transposon.

Cloning, sequencing, and expression of the pyruvate carboxylase gene in Lactococcus lactis subsp. lactis C2.

A functional pyc gene was isolated from Lactococcus lactis subsp. lactis C2 and was found to complement a Pyc defect in L. lactis KB4. The deduced lactococcal Pyc protein was highly homologous to Pyc sequences of other bacteria. The pyc gene was also detected in Lactococcus lactis subsp. cremoris and L. lactis subsp. lactis bv. diacetylactis strains.
