Abstract
The formation of exopolysaccharides (EPS) by Pediococcus damnosus strain 2.6 was investigated in two different high P-glucan suspensions of oat (OBC) and barley (BBC). Bacterial growth was confirmed by measuring pH, colony forming units (cfu), viscosity and ropiness during growth. Growth and an increase in viscosity of the beta-glucan suspension based on oat were observed whereas only a minor growth and no significant effect on viscosity was seen in the beta-glucans suspension based on barley. Higher bacterial growth and higher final viscosity and ropiness were observed in samples that were mixed with the OBC and an ordinary commercial oat-base (Adavena(R) G40). These results show the potential of using a combination of a high beta-glucan... (More)

Higher bacterial growth and higher final viscosity and ropiness were observed in samples that were mixed with the OBC and an ordinary commercial oat-base (Adavena(R) G40). These results show the potential of using a combination of a high beta-glucan suspension of cereals to generate fermented products containing both high levels of native beta-glucans from oats or barley and also microbial beta-glucans from the starter culture.
