En plus des améliorations que l’on peut encore apporter en matière de zootechnie et de prophylaxie traditionnelle, des méthodes alternatives sont maintenant disponibles ou en développement.

Abstract:
A marine epidemic of wasting disease decimated populations of eelgrass, Zostera marina L., in the early 1930s. Labyrinthula, a marine slime mold was the suspected pathogen, although the cause was never clearly determined. Presently, a recurrence of wasting disease of Z. marina was documented in populations along the coasts of North America and Europe. A pathogenic species of Labyrinthula, described as Labyrinthula zosterae Porter et Muehlstein, was identified as the primary microorganism causing the present wasting disease. Of all the microorganisms tested in laboratory disease tests, only L.

Sessile microorganisms accelerate various reactions during electrochemical corrosion of materials.

Abstract:
Abstract The adhesion of microorganisms onto materials surface mediated by extracellular polymeric substances (EPS) lead to an important modification of the metal-solution interface. The requirement of modem civilization with the hightened sense of environmental responsibilities and quality of life can be met by using some eco-friendly microbiocides with different spectra of activity. Some n2o2 donor schiff base compounds were synthesized and characterized by IR, NMR and ESR spectroscopy. These compounds were found effective in controling the growth of biofilm of E. соli, Pseudomonas fluoresce

Abstract:
Abstract A significant percentage of the corrosion failures in many industries are caused or accelerated by the effects resulting from the activities of specific microorganisms. In aqueous environments, microorganisms tend to attach themselves to metal surfaces and form biofilms. These biofilms create nonuniform surface conditions, leading to severe localized pitting microbiologically influenced corrosion (MIC). In this study a numerical model was developed to study the anaerobic pitting MIC of steel in sulfate-reducing bacteria (SRB) environments. The transient two-dimensional model in cylind

Abstract:
Microplastics are extremely small mixed shaped plastic debris in the environment. These plastics are manufactured (primary microplastics) or formed from the breakdown of larger plastics once they enter the terrestrial, freshwater and marine environments (secondary microplastics). Over time, a combination of physical, photochemical and biological processes can reduce the structural integrity of plastic debris to produce microplastics and even further to produce nanoplastics. NMPs have been detected in both the aquatic and terrestrial environments and can be easily spread by water, soil and air
