For millennia, nature was the only source of medicine for mankind. Even today natural products represent a large proportion of the drugs in use. In some areas, like cancer or infectious diseases, about 50 % of the compounds used are of natural origin. Cyan ...
Because plants are static and live in a competitive and sometimes hostile environment, they have evolved mechanisms that protect them from abiotic and biotic stress. These mechanisms include detoxification and sequestration of xenobiotic compounds and of h ...
Background, aim and scope Sulphonated anthraquinones are precursors of many synthetic dyes and pigments, recalcitrant to biodegradation and thus not eliminated by classical wastewater treatments. In the development of a phytotreatment to remove sulphonated ...
This review presents natural products from cyanobacteria. Several classes of secondary metabolites are highlighted. Toxic metabolites from these prokaryotic photosynthetic organisms include compounds such as microcystin, anatoxin and saxitoxin, which displ ...
Pseudomonas entomophila is an entomopathogenic bacterium that is lethal to Drosophila melanogaster within 1-2 days of ingestion of high doses. Flies orally infected with P. entomophila rapidly succumb despite the induction of both local and systemic immune ...
Sulfonated anthraquinones are precursors of many synthetic dyes and pigments, recalcitrant to biodegradation and thus not eliminated by classical wastewater treatments. In the development of a phytoremediation process to remove sulfonated aromatic compound ...
Current advanced molecular biology techniques provide gene expression (mRNA) levels of selected genes of an organism. In such aggregate, the mRNA level of one gene is mediated by the presence of specific proteins and metabolites produced by other genes. Ge ...
The giant unicellular macroalgae exhibit an extraordinary wound repair mechanism. The rapid assimilation of cellular contents into an insoluble wound plug prevents detrimental cytoplasmic loss and limits the intrusion of extracellular components which coul ...
Induced chemical defense reactions are widespread in marine brown algae. Despite the evidence that the biosynthesis of defense metabolites can be up-regulated upon herbivory, we do not know how this regulation of biosynthetic pathways to secondary metaboli ...
A single spectra library was used to monitor on-line, by mid-infrared spectroscopy, nine different batch cultures of Escherichia coli performed with various medium compositions, including chemically complex formulations. Whereas the classic chemometrics ap ...
