Sea urchins rely on chemical senses to localize suitable food resources, therefore representing model species for chemosensory studies. In the present study, we investigated sensitivity of Mediterranean sea urchin Paracentrotus lividus blue-green alga Aphanizomenon flos-aquae, namely “Klamath”, and a few amino acids chosen from biochemical composition same algae. To this end, used “urchinogram”...

Abstract Background Cyanobacteria and their toxins occur in high concentrations during the so-called bloom events surface waters. To be able to assess risks associated with cyanobacterial blooms, we need understand persistence fate processes of these other bioactive metabolites. In this study, investigated photochemical 54 cyanopeptides extracted from two strains Microcystis aeruginosa (PCC7806...

Flos Chrysanthemi, dried flower of Chrysanthemum morifolium Ramat, has drawn much attention recently owing to its potential beneficial health effects for human. Flos Chrysanthemi products are usually taken orally and metabolized by intestinal microflora. However, there has been no investigation of the comprehensive metabolic profile of the Flos Chrysanthemi extract by intestinal flora owing to ...
