EpsA is an essential gene in exopolysaccharide production in Lactobacillus johnsonii FI9785

Dertli E.; Mayer M.J.; Colquhoun I.J.; Narbad A. (John Wiley and Sons Ltd, 2016)

Lactobacillus johnsonii FI9785 has an eps gene cluster which is required for the biosynthesis of homopolymeric exopolysaccharides (EPS)-1 and heteropolymeric EPS-2 as a capsular layer. The first gene of the cluster, epsA, ...
Structural analysis of the ?-D-glucan produced by the sourdough isolate Lactobacillus brevis E25

Dertli E.; Colquhoun I.J.; Côté G.L.; Le Gall G.; Narbad A. (Elsevier Ltd, 2018)

Cereal-associated Lactic Acid Bacteria (LAB) are well known for homopolymeric exopolysaccharide (EPS) production. Herein, the structure of an EPS isolated from sourdough isolate Lactobacillus brevis E25 was determined. A ...
Structure and biosynthesis of two exopolysaccharides produced by lactobacillus johnsonii FI9785

Dertli E.; Colquhoun I.J.; Gunning A.P.; Bongaerts R.J.; Le Gall G.; Bonev B.B.; Mayer M.J.; Narbad A. (2013)

Exopolysaccharides were isolated and purified from Lactobacillus johnsonii FI9785, which has previously been shown to act as a competitive exclusion agent to control Clostridium perfringens in poultry. Structural analysis ...
