Biodiversity of wild Lactococcus lactis and their geo-spatial relationship with the environment

Lactic acid bacteria are distributed in nature, isolating themselves from diverse ecosystems and presenting a wide metabolic biodiversity. In Corrientes (Argentina), artisanal cheeses and their specifi c environment are an important source of autochthonous lactic acid bacteria. The objective of t...
