Environmental factors can alter exopolysaccharide biosynthesis in lactic acid bacteria (LAB). To further clarify this potential relationship, the mRNA expression of genes involved in exopolysaccharide synthesis such as glmU, pgmB1, cps4E, cps4F, cps4J, and cps4H in Lactiplantibacillus plantarum VAL6 under different conditions including temperature, pH, sodium chloride (NaCl), and carbon dioxide (CO2) intensification culture was studied. The transcriptomic data revealed that the exposure of L. plantarum ...

Abstract To investigate the effect of environmental stresses on the exopolysaccharide biosynthesis, after 24 h of culture at 37 °C with pH 6.8 and without sodium chloride, Lactobacillus plantarum VAL6 was exposed to different stress conditions, including pH (pHs of 3 and 8) and high sodium chloride concentration treatments. The results found that Lactobacillus plantarum VAL6 exposed to stress at pH 3 for 3 h gives the highest exopolysaccharide yield (50.44 g/L) which is 6.4 fold higher than non-stress. ...

Results are presented on strange particle channel and reaction cross sections in 5 GeV/c π+p collisions. For the (quasi-) two body reactions π+p→Σ+K+, π+p→Σ+K∗+ (890), π+p→Σ+(1385)K+ and π+p→Σ+(1385)K∗+(890) the differential cross sections and spin density matrix elements are given. A20 and t0 production in the (KK)0 mode is estimated using a technique which eliminates A20f0 interference. Proton dissociation into strange particle pairs is investigated. A comparison is made of some of our reactions ...

Phu Tho Nguyen, Ouali Amiri,

In this paper, a physical model of chloride ingress concretes is proposed. The originality of the model lies in its consideration of electrical double layer (EDL) phenomenon in unsaturated concrete. The EDL is occurring at the interface between pore walls and pore solution. The work is performed by solving the multispecies ionic transport equations coupled with those of humidity. To show the effect of slag and fly ash, several concretes were considered. The chloride profile was simulated. The results ...

In this paper, we suggest a modelling of chloride ingress in unsaturated concretes. The originality of our model lies in its consideration of the electrical double layer (EDL), the temperature as well as the isotherm sorption-desorption hysteresis. In order to consider slag and fly ash effects, several concretes were considered and experimentally tested in tidal conditions. The chloride profile was simulated by a multispecies model. The simulations show that the chloride concentration increases with ...
