Bacterial culture was the first method used to describe the human microbiota, but this
method is considered outdated by many researchers. Metagenomics studies have since …

Whether a small cell, a small genome or a minimal set of chemical reactions with self-
replicating properties, simplicity is beguiling. As Leonardo da Vinci reportedly said,'simplicity …

Phytoplankton blooms characterize temperate ocean margin zones in spring. We
investigated the bacterioplankton response to a diatom bloom in the North Sea and …

BACKGROUND Marine ecosystems are composed of a diverse array of life forms, the
majority of which are unicellular—archaea, bacteria, and eukaryotes. The power of these …

SAR11 is a group of small, carbon-oxidizing bacteria that reach a global estimated
population size of 2.4× 1028 cells—approximately 25% of all plankton. They are found …

Reports of biogenic methane (CH4) synthesis associated with a range of organisms have
steadily accumulated in the literature. This has not happened without controversy and in …

Methionine is essential in all organisms, as it is both a proteinogenic amino acid and a
component of the cofactor, S-adenosyl methionine. The metabolic pathway for its …

Ocean warming occurs every year in seasonal cycles that can help us to understand long-
term responses of plankton to climate change. Rhythmic seasonal patterns of microbial …

Phytoplankton physiology is dynamic and highly responsive to the environment.
Phytoplankton acclimate to changing environmental conditions by a complex reallocation of …

Abstract The Hawaii Ocean Time-series (HOT) programme has been tracking microbial and
biogeochemical processes in the North Pacific Subtropical Gyre since October 1988. The …
