Marine ecosystem model analysis using data assimilation
Numerical modelling of the marine ecosystem requires the aggregation of diverse chemical and biological species into broad categories. To avoid large bias errors it is preferable to resolve as many explicit state variables and processes as possible.

Rice (Oryza sativa L.), a key staple crop, contributes over 20% of the daily caloric intake for more than 3.5 billion people worldwide. The continuous growth of the global population necessitates a steady increase in rice production, promoting ...

Abstract Mixed‐culture fermentation generally produces volatile fatty acids (VFAs) as a mixture of C2–C6 acids. Among operational parameters, temperature has a distinct effect on the microorganisms' metabolic activity, which can shift the composition of the metabolites.

Quantifying the fate of wastewater nitrogen discharged to a Canadian river
Addition of nutrients, such as nitrogen, can degrade water quality in lakes, rivers, and estuaries. To predict the fate of nutrient inputs, an understanding of the biogeochemical cycling of nutrients is needed. We develop and employ a novel, parsimonious,

Nitrogen Fixation and Translocation in Sugarcane [PDF]
World sugarcane production is increasing rapidly as a biofuel. In some areas in Brazil, sugarcane has been grown continually over very long periods without N fertiliser inputs. Therefore, the occurrence of N fixation has been suspected.

Abstract Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris, its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attractive for pharmaceutical and ...

Carbon and oxygen fluxes during photoautotrophic, photoheterotrophic and mixotrophic growth of Scenedesmus obliquus. ABSTRACT Mixotrophic growth of microalgae involves the simultaneous assimilation of inorganic and organic carbon sources, but the quantitative contributions of photoautotrophic and photoheterotrophic metabolisms remain poorly resolved ...

Markers and signals associated with nitrogen assimilation in higher plants
A key concept underpinning current understanding of the carbon/nitrogen (C/N) interaction in plants is that the capacity for N assimilation is aligned to nutrient availability and requirements by the integrated perception of signals from hormones ...
