Diazotrophic marine cyanobacteria in the genus Trichodesmium contribute a large fraction of new nitrogen entering oligotrophic oceans, but little is known about how they respond to shifts global change variables such as carbon dioxide (CO 2 ) and temperature. We compared dinitrogen (N CO fixation rates during steady‐state growth under past, current, future scenarios, at two relevant temperatures. At projected levels year 2100 (76 Pa, 750 ppm), N Pacific Atlantic isolates increased 35–100%,...

BackgroundThe miniaturised and portable DNA sequencer MinION™ has been released to the scientific community within framework of an early access programme evaluate its application for a wide variety genetic approaches. This technology demonstrated great potential, especially in genome-wide analyses. In this study, we tested ability system perform amplicon sequencing order design new approaches study microbial diversity using nearly full-length 16S rDNA sequences.

Grape seed proanthocyanidin extract (GSPE) modulates several parameters involved in metabolic syndrome. GSPE is a mixture of compounds, some which are rapidly absorbed, while others remain the lumen where they might have effects that translated to whole organism. Our aim was decipher if 8-day treatment GSPE, previously shown reduce food intake, induces changes microbiota and enterohormone secretion. The ratio Firmicutes : Bacteroidetes lower GSPE-treated rats compared controls, differences...

Quantitative real‐time PCR (QPCR) is a powerful and sensitive method for quantitative detection of microorganisms. Application this methodology enumeration harmful algal bloom (HAB) species has the potential to revolutionize our approach HAB research, making it possible identify correlations between cell abundances factors that regulate dynamics. Its application ecological studies, however, produced mixed results. QPCR assays typically rely on generation standard curves from plasmids or...

Abstract This study investigated the immune mechanisms whereby administration of Bacteroides uniformis CECT 7771 reduces metabolic dysfunction in obesity. C57BL/6 adult male mice were fed a standard diet or Western high fat and fructose, supplemented not with B. for 14 weeks. reduced body weight gain, plasma cholesterol, triglyceride, glucose, leptin levels; improved oral glucose tolerance obese mice. Moreover, modulated gut microbiota alterations associated obesity, increasing Tregs...

The gut microbiota coexists in partnership with the human host through adaptations to environmental and physiological changes that help maintain dynamic homeostatic healthy states. Break-down of this delicate balance under sustained exposure stressors (e.g. unhealthy diets) can, however, contribute onset disease. Diet is a key modifiable factor modulates its metabolic capacities that, turn, could impact physiology. On basis, diet act as synergistic forces provide resilience against disease...

Obesity is a chronic metabolic disease of high complexity and multifactorial origin. Understanding the effects nutrition on childhood obesity metabolism remains challenge. The aim this study was to determine fatty acid (FA) profile red blood cell (RBC) membranes as comprehensive biomarker children’s metabolism, together with evaluation their dietary intake. An observational carried out 209 children (107 healthy controls, 41 who were overweight 61 obesity) between 6 16 years age. Mature RBC...

Microbial biofilms are essential components in the elimination of pollutants within biofilters, yet still little is known regarding complex relationships between microbial community structure and biodegradation function these engineered ecosystems. To further explore this relationship, 16S rDNA tag pyrosequencing was applied to samples taken at four time points from a styrene-degrading biofilter undergoing variable operating conditions. Changes were observed different stages operation, level...

This work intends to describe the physical properties of red blood cell (RBC) membranes in obese adults. The hypothesis driving this research is that obesity, addition increasing amount body fat, will also modify lipid composition cells other than adipocytes.

Raphidophytes (class Raphidophyceae) produce high levels of reactive oxygen species (ROS), yet little is known regarding cellular scavenging mechanisms needed for protection against these radicals. Enzymatic activities the antioxidants superoxide dismutase (SOD) and catalase (CAT) were measured in conjunction with production (O 2 •− ) hydrogen peroxide (H O batch cultures five different raphidophytes during early exponential, late‐exponential, stationary growth phases. The greatest...
