Abstract

Microbes possess a great genetic repertoire and metabolic versatility that allow them to face the extreme conditions of the deep sea, drive the biogeochemical cycles, and feed chemosynthetic web chains. These microbes respond to historical, global, regional, and local processes in deep-sea habitats and are influenced by microenvironmental variations and the availability of nutrients and electron acceptors to move and survive. By the use of a suite of different methods, as omics techniques and in situ measurements, buoyant particles and the light-independent chemoautotrophic microbes are increasingly being considered as important carbon sources to heterotrophic biota below the euphotic zone. Studies conducted in asphalt seeps, gas hydrates, sunken organic substrates, natural whale carcasses, and seamounts in the Southwestern Atlantic Ocean have revealed a largely unknown diversity of microbes and their high potential for biotechnology. Further promising discoveries are about to come with increasing efforts to determine the microbial community composition, their metabolic diversity, and ecological role in the deep ocean across oceanographic features.
