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.

Abstract:
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

Abstract:
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
