This work reports the results of the study for cadmium binding by the dead red macroalga Mastocarpus stellatus. Kinetics sorption experiments demonstrated the high rate of metal biosorption: the system attained over 50% of the total biomass cadmium uptake within 2 min of contact and over 90% in the first 9 min. The kinetic data were successfully described by a pseudo-second order model with rat...

Morphological variation was analyzed in wild, managed in situ, and cultivated populations of the columnar cactus Stenocereus stellatus in central Mexico. The purpose was to evaluate whether morphological divergence between manipulated and wild populations has resulted from domestication processes. Variation of 23 morphological characters was analyzed among 324 individuals from 19 populations of...

Abstract This study focusses on the valorization of red seaweed Mastocarpus stellatus, collected in Northern coast Portugal, as a natural source high value compounds due to its beneficial properties. An annual monitoring was performed by determining lipids, ash, carbohydrates, phycobiliproteins, total phenolic compounds, antioxidant capacity and carrageenan from three different rocky shores loc...

Intraspecific and interspecific nucleotide sequence variations of the mtDNA control region (D-loop) were studied with mtDNAs isolated from tissue specimens of more than 1400 sturgeons of nine species: Russian sturgeon Acipenser gueldenstaedtii , Persian sturgeon A. persicus , Siberian sturgeon A. baerii , Amur sturgeon A. schrenkii , Fringebarbel sturgeon A. nudiventris , sterlet A. ruthenus , ...

According to the lactadehydrogenase locus, genetic diversity of 9 samples Volga sevryuga different origin was studied. In total, 733 pieces young sevryuga, 99 producers and 107 were four-year-olds with MPERZ. To assess variability lactate dehyrogenase allozymes, method polyacrylamide gel electrophoresis used, as most appropriate for assessing influence environment in natural domesticated popula...
