The Importance of Marine Picoeukaryotes and the Search for Lost Time

submitted by: dougramsey
Unicellular eukaryotes are responsible for a massive amount of photosynthetic carbon fixation in marine systems. The smallest among these fall within the “pico” size fraction (<2 micrometers in diameter), are broadly distributed – from coastal to open-ocean environments – and are highly diverse. Picoeukaryotes contribute a significant proportion of the biomass and primary production within this size fraction, often rivaling their cyanobacterial counterparts Prochlorococcus and...

Metabonomic profiling of the gut microbiome: Implications for human health James Kinross, Imperial College, London

submitted by: dougramsey
Microbial-mammalian metabolic cooperation is defined as the human ‘metabonome’. Transgenomic co-metabolic interactions within the metabonome greatly increase system complexity and this presents a significant challenge for elucidating the mechanisms by which the intestinal micro biome influences the host phenotype. By measuring and mathematically modelling changes in the levels of products of metabolism found in mammalian biological fluids and tissues, metabonomics offers fresh insight...

The Human Oral Microbiome by Floyd Dewhirst, Harvard University

submitted by: dougramsey
The human oral cavity is a diverse habitat that contains approximately bacterial 600 predominant species. The oral microbiome is comprised of 44% named species, 12% isolates representing unnamed species, and 44% phylotypes known only from 16S rRNA based cloning studies. Species from 11 phyla have been identified: Firmicutes (211), Bacteroidetes (106), Proteobacteria (99), Actinobacteria (64), Spirochaetes (49), Fusobacteria (29), TM7 (12), Synergistetes (10), Chlamydiae (1), Chloroflexi (1)...
