Malgré des réglementations contraignantes, l’usage des antibiotiques en préventif est encore répandu en aquaculture, particulièrement pendant les phases critiques (stades précoces, métamorphose, transferts d’animaux), mais aussi chez des animaux en croissance. 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. Les préparations microbiennes commercialisées pour les élevages terrestres sont de plus en plus utilisées pour les élevages de crevettes et de

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.

After 40 years of intensive research, chemistry of marine natural products has become a mature field. Since 1995, there are signals of decreased interest in the search of new metabolites from traditional sources such as macroalgae and octocorals, and the number of annual reports on marine sponges stabilized. On the contrary, metabolites from microorganisms is a rapidly growing field, due, at least in part, to the suspicion that a number of metabolites obtained from algae and invertebrates may be produced by associated microorganisms.

To isolate representative and abundant chitinase genes from uncultivated marine bacteria, we constructed libraries of genomic DNA isolated from coastal and estuarine waters. The libraries were screened for genes encoding proteins that hydrolyze a fluorogenic analogue of chitin, 4-methylumbelliferyl β-d-N,N′-diacetylchitobioside (MUF-diNAG). The abundance of c

Streszczenie:

Los vertidos de aguas residuales en los ecosistemas acuáticos son fuente de microplásticos y microorganismos patógenos, que afectan la calidad ambiental y representan un riesgo para la biodiversidad y la salud humana. Los objetivos de esta revisión fueron: (i) analizar los impactos de los vertimientos de aguas residuales sobre la calidad sanitaria de aguas costeras de Colombia, y (ii) examinar los posibles riesgos ambientales de las interacciones entre microorganismos–microplásticos. Durante el 2021, en el marco del monitoreo ambiental marino de Colombia se midieron los coliformes termotoleran

Marine environments harbor a vast diversity of microorganisms capable of producing bioactive pigments with significant industrial and therapeutic potential. This study focuses on the isolation, characterization, and biological evaluation of pigment-producing microorganisms from marine soil samples collected at Kovalam, Besant Nagar, and Marina beaches in Tamil Nadu, India. The research aims to identify potent microbial strains that synthesize pigments with antimicrobial and antioxidant properties, offering eco-friendly alternatives to synthetic dyes. The methodology involved collection of mari

En esta contribución se planteó el objetivo de resolver la problemática que se enfrenta al trabajar con técnicas de biología molecular para la extracción de DNA obtenido de material particulado marino en suspensión, y se presenta un propuesta de cómo pueden ser resueltos estos problemas. Los protocolos comúnmente empleados fueron modificados para optimizar la cantidad de DNA total extraído, incrementado así la probabilidad de la amplificación de genes funcionales. Se presentan, además, resultados de la selección de sitios hipervariables para el 16S rRNA, así como para los genes nirS, nirK y no

Marine hydrocarbon seeps, due to their unique geophysical and geochemical characteristics, form unique conditions for the development of specific microbial communities. Diverse and interconnected metabolic activities of them underlie global ecological processes. In this review were considered the geophysical and chemical conditions for the formation of seepages and hydrocarbon fluids – energy sources and substrates for metabolic processes mediated by microorganisms that exist in these ecological niches. It was presented the information about microbial biodiversity in cold hydrocarbon seeps, it
