Cytogenetic and photosynthetic responses of plants after exposure to water from a lake environment.

Plants are sensitive to environmental pollutants and are excellent organisms for genetic and physiological testing. Plant-based test systems are often used to study aquatic, aerial, and terrestrial pollution, especially Allium cepa, but studies with Tradescatia pallida specimens have gained prominence due to their sensitivity and applicability. Among the biomarkers, cytogenetic damage and chlorophyll levels are used in stress studies due to their responses to single or combined factors.

Cytotoxicity, chemical, and nutritional profile evaluation of biomass extracts of the (duckweed) aquatic plant.

(duckweed) is the smallest and fast-growing aquatic plant species producing protein-rich biomass with high protein nutritional value, phytoremediation capacity, and nutrient removal from wastewater. Duckweed may also be used as a new potential bioreactor for biological products, such as vaccines, antibodies, and pharmaceutical proteins. Based upon the potential importanc of in phytoremediation and as a bioreactor the aim of this study was to (1) characterize the chemical and nutritional profiles of biomass utilizing an integrated multi-trophic aquaculture system (IMTA) and a pond, and (2) investigate the cytotoxic potential of different concentrations of organic extracts and fractions using the MTT bioassay.

Determination of the antimutagenicity of an aqueous extract of Rhizophora mangle L. (Rhizophoraceae), using in vivo and in vitro test systems.

An aqueous extract of Rhizophora mangle L. bark is used as raw material in pottery making in the State of Espirito Santo, Brazil. This extract presents large quantities of tannins, compounds possessing antioxidant properties.
