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, ... -
Impact of the exopolysaccharide layer on biofilms, adhesion and resistance to stress in Lactobacillus johnsonii FI9785
Dertli E.; Mayer M.J.; Narbad A. (BioMed Central Ltd., 2015)Background: The bacterial cell surface is a crucial factor in cell-cell and cell-host interactions. Lactobacillus johnsonii FI9785 produces an exopolysaccharide (EPS) layer whose quantity and composition is altered in ... -
Spontaneous Mutation Reveals Influence of Exopolysaccharide on Lactobacillus johnsonii Surface Characteristics
Horn N.; Wegmann U.; Dertli E.; Mulholland F.; Collins S.R.A.; Waldron K.W.; Bongaerts R.J.; Mayer M.J.; Narbad A. (2013)As a competitive exclusion agent, Lactobacillus johnsonii FI9785 has been shown to prevent the colonization of selected pathogenic bacteria from the chicken gastrointestinal tract. During growth of the bacterium a rare but ... -
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 ...
