Diversity and genomics of Antarctic marine micro-organisms.
Marine bacterioplanktons are thought to play a vital role in Southern Ocean ecology and ecosystem function, as they do in other ocean systems. However, our understanding of phylogenetic diversity, genome-enabled capabilities and specific adaptations to this persistently cold environment is limited. Bacterioplankton community composition shifts significantly over the annual cycle as sea ice melt...
متن کاملEconomic Importance of Marine Micro Organisms
Bacteria and allied micro-organisms are of direct economic concern to man in many ways besides causing diseases and bringing about the decomposi tion of marine a,nimals and commercial algae . There are many p roblems in the general economy of the ocean , the solu tio n of which requi res the a id of the microbio log ist. The m ic ro-organisms belong to a wide range of groups and include bacteri...
متن کاملUnity and diversity in the metabolism of micro - organisms 1924
the salt of the volatile acid, and the bacteria, is treated with a known uantity of normal hydrochloric aci 3 and the carbon dioxide is expelled by heating. Following this, a titration with normal alkali and phenolphthaleine as indicator, shows how much calcium carbonate is produced and consequently how much of the organic salt is oxidized. After addition of a little sulfuric acid the liquid is...
متن کاملMicrobial diversity associated with tetrodotoxin production in marine organisms.
Tetrodotoxin (TTX), is a potent neurotoxin found in genetically diversed organisms. Many TTX producing microorganism have also been isolated from TTX bearing animals. The TTX producing microbes found in four different phylum (Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes), the Proteobacteria are the dominating one. In most of the cases, TTX producing microbes are found in the int...
متن کاملChemotactic response of marine micro-organisms to micro-scale nutrient layers.
The degree to which planktonic microbes can exploit microscale resource patches will have considerable implications for oceanic trophodynamics and biogeochemical flux. However, to take advantage of nutrient patches in the ocean, swimming microbes must overcome the influences of physical forces including molecular diffusion and turbulent shear, which will limit the availability of patches and th...
