Activating Compound

Activating Compound	Comment	Organism	Structure
additional information	exhibits 2.5-fold-higher GDH activity than cells are grown in milk, instead of glucose	Lactococcus lactis

Application

Application	Comment	Organism
food industry	is responsible for the capacity of Lactococcus lactis strains to catabolize amino acids to aroma compounds, pGdh442 can be naturally transmitted to other Lactococcus lactis strains by using cadmium or zinc resistance as a selectable marker, new prospects to intensify and diversify the production of aroma compounds in cheese	Lactococcus lactis

Cloned(Commentary)

Cloned (Comment)	Organism
overexpression with the NICE system in Lactococcus lactis TIL46 induced with increasing concentrations of nisin, pGdh442 transferred by electroporation (TIL504) or by conjugation (TIL507) in Lactococcus lactis MG1363 or in its derivative TIL193 strain containing pGhost8, appears to be stable after several subcultures of the strains without selection pressure, in the presence of plasmid pLP712, pGdh442 is unstable	Lactococcus lactis
