Biological and chemical characterization of new isolated halophilic microorganisms from saltern ponds of Trapani, Sicily
2021
Abstract Halophilic microorganisms inhabiting hypersaline environments such as salt lakes, Dead Sea, or salt evaporation ponds, have acquired specific cell adaptation to grow within stressful conditions. In this study, we isolated heterotrophic and autotrophic microorganisms from several saltern ponds located at the Natural Reserve “Saline di Trapani e Paceco”, Sicily, Italy. The aim of the study was to investigate the biotechnological potential of new microbial strains from saltern ponds, by capturing their biological and chemical diversity. After the isolation and identification of the sampled strains, their growth capacity was determined under low and high salinity conditions. The metabo…
Astrobiology of life on Earth
2021
Astrobiology is mistakenly regarded by some as a field confined to studies of life beyond Earth. Here, we consider life on Earth through an astrobiological lens. Whereas classical studies of microbiology historically focused on various anthropocentric sub-fields (such as fermented foods or commensals and pathogens of crop plants, livestock and humans), addressing key biological questions via astrobiological approaches can further our understanding of all life on Earth. We highlight potential implications of this approach through the articles in this Environmental Microbiology special issue ‘Ecophysiology of Extremophiles’. They report on the microbiology of places/processes including low-te…
Bacterias halófilas moderadas aisladas de las minas salinas de Atacocha - Ayacucho
2007
Las bacterias halófilas producen una gran variedad de metabolitos y enzimas con interesantes aplicaciones bíotecnológicas. Con la finalidad de aislar bacterias halófilas moderadas de las minas salinas de Atacocha - Ayacucho, se recolectaron muestras de sal y se preenriquecieron en medio agua de sales al 5% suplementado con extracto de levadura al 0.5% durante una semana y luego se sembraron en medio sólido. De 40 aislados se seleccionaron 10 por presentar características morfológicas y culturales muy diferenciadas. A los aislados seleccionados se les determinó el rango de tolerancia al NaCl, temperatura, pH y sus características bioquímicas y nutricionales. Se encontró que los aislados tole…
