Viral density and virus-to-bacterium ratio in deep-sea sediments of the Eastern Mediterranean

Article Abstract:

Virus-to-bacteria ratios and viral densities have been studied in deep-sea sediments of the Eastern Mediterranean at three sites. The role played by viruses in controlling deep-sea benthic bacterial assemblages in biogeochemical cycles is less relevant than in pelagic systems. Virus density went up vertically with depth in sediment cores at all stations.

Viral density and virus-to-bacterium ratio in deep-sea sediments of the Eastern Mediterranean

Article Abstract:

Research has been conducted on the bacterial and viral densities. The determination of these densities at deep-sea stations has been performed.

Enzymatic activity, bacterial distribution, and organic matter composition in sediments of the Ross Sea (Antarctica)

Article Abstract:

A study was conducted to analyze the enzymatic activities of aminopeptidase and beta-glucosidase in Antarctic Ross Sea sediments. Lipids were obtained from dried sediments samples using direct elution with chloroform and methanol. Results indicated that the enzyme-dependent transformation of organic matter in Antarctic Ross Sea sediments correlates with a rate similar to those determined in temperate environments.
