Excessive molecular weight dextrans enhance the rheological properties of fermented merchandise and have immunomodulatory and antiviral exercise. We report on 5.84 × 107-2.61 × 108 Da dextrans produced by Leuconostoc lactis AV1n, Weissella cibaria AV2ou and Weissella confusa V30 and FS54 strains. Dextransucrases catalyze dextran synthesis by sucrose hydrolysis concomitant with fructose technology. The 4 micro organism have dextransucrases with molecular weight of about 160 kDa detected by zymograms. Every bacterium confirmed totally different interaction of dextran manufacturing and metabolic fluxes. All micro organism produced lactate, and AV2ou aside, synthesized mannitol from fructose. FS54 hydrolyzed dextran blue and the focus of dextran produced by this bacterium decreased throughout the stationary part. The AV1n binding to Caco-2 cells and polystyrene plates was larger underneath circumstances for dextran synthesis.
Thus, that is the primary occasion of a Weissella dextranase, related to a dextransucrase means, and of a optimistic affect of dextran on adhesion and aggregation properties of a bacterium. 300 Clostridium strains had been remoted from spoiled wurstels and had been recognized by conventional and molecular strategies as Clostridium perfringens. The phenotypic traits of the strains had been studied. All of the strains produced acetic and butyric acids and enterotoxin. C. perfringens grew within the spoiled wurstels as a result of it was current in uncooked meat (Lot 150) at a degree of three.2 log CFU/g attributable to an unchecked cooling part that took 28 h to lower the temperature of the wurstels from 60 to 9-10 °C, which is the decrease restrict for C. perfringens development.
Through the 28 h of cooling, the focus of C. perfringens elevated to six.5 CFU/g. It was concluded that its presence and the lengthy cooling time had been the principle components chargeable for the spoilage. Wurstels deliberately made with contaminated meat (Three log CFU/g) however cooled after cooking for 17 h to 9 °C didn’t help C. perfringens development; consequently, these wurstels remained unspoiled. The packages of the spoiled wurstels had been blown, and the merchandise had been gentle (soggy), textureless and had the odour of acetic acid, ethanol and sulfur.
