ADDCON Lactobacilli do it better!

05/02/19

Intensive formation of Extracellular Polymeric Substances now proven.

New research on ADDCON’s lactic acid bacteria (Lactobacillus plantarum) revealed that the high efficiency and environmental stability of our microbes can be explained by the existence of extracellular polymeric substances (EPS).

EPS improve moisture retention, creating ideal conditions for the lactic acid bacteria. Up to 97 % of the EPS-matrix may consist of adsorbed water, thus the water activity (aw-value) for the lactic acid bacteria is improved and the growth of spoilage organisms inhibited. Furthermore, the supply of exploitable nutrients is improved. The EPS also protect the lactic acid bacteria against adverse chemical and physical conditions, like anti-nutrients or growth inhibiting substances, or broad temperature variation.

The ability of microbes to form EPS varies widely between species and strains.

The current studies show that ADDCON’s Lactobacillus plantarum is characterized by a strong formation of EPS. This results in a safe fermentation and anaerobically stable and palatable silages.
