Superior esterolytic activity in environmental Lactococcus lactis strains is linked to the presence of the SGNH hydrolase family of esterases
Lactococcus lactis strains are widely used in the dairy industry in fermentation processes for production of cheese and fermented milks. However, the esterolytic activity of L. lactis is not generally considered high. For this reason, purified microbial lipases and esterases are often added in certa...

description | Lactococcus lactis strains are widely used in the dairy industry in fermentation processes for production of cheese and fermented milks. However, the esterolytic activity of L. lactis is not generally considered high. For this reason, purified microbial lipases and esterases are often added in certain dairy processes to generate specific flavors in the final food product. This work demonstrates the superior esterolytic activity of a collection of L. lactis strains isolated from different environmental sources compared with that of dairy-derived strains. It provides further evidence of the more diverse metabolic capabilities displayed by L. lactis strains from environmental sources compared to their domesticated dairy counterparts. Furthermore, the presence of a 1,287-bp gene encoding a 428-amino acid SGNH hydrolase in the high-esterolytic environmental strains suggests a possible link between superior esterolytic activity and the presence of the esterase from the SGNH hydrolase family. |
