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.

Physiological and toxicological response of BCCUSP232 exposed to extracts.

is one of the most predominant freshwater bloom-forming cyanobacterium found globally which is capable of producing toxic secondary metabolites including microcystins that might intoxicate animals and humans when contaminated water or food is ingested. Aubl is one of the plants that might possess bioactive compounds capable of controlling growth and reproduction of . The present study aimed to determine the presence of bioactive compounds in extracts and determine alterations occurred in growth and reproduction of when exposed to these plant extracts.

Cytogenotoxicity evaluation of heavy metals detected in extracts and infusion of , potential bioaccumulator plant.

Heavy metals (HMs) are natural components of the Earth's crust that might originate from natural and anthropogenic sources. In excess quantities, the presence of these metals is harmful for both environment and human health. Taking this into account, various investigators examined bioaccumulator species in order to reduce environmental toxicity, among these .

Cytogenotoxic, insecticidal, and phytotoxic activity from biomass extracts of the freshwater algae .

Agroecology, the application of ecological concepts to agricultural production, has been developing over the last years with consequent promotion for discovery of bioactive compounds to control pests and abolish crop diseases. In this context, algae from genus are characterized by high potential for bioeconomic applications due to (1) available biomass for harvesting or cultivation and (2) production of allelochemicals, which present a potential to protect field crops from insect infestation. Therefore, this study aimed to determine primary and secondary metabolites derived from aqueous and hydroethanolic extracts of and to evaluate phytotoxic, cytogenotoxic, insecticidal, and pro-oxidative activities of these extracts.

Coastal degradation impacts on green turtle's (Chelonia mydas) diet in southeastern Brazil: Nutritional richness and health.

This study evaluated the influence of environmental degradation on the nutritional value of the main marine macrophytes consumed by green sea turtles (Chelonia mydas) in areas with different degrees of urbanization. Macrophyte assemblages in the highly urbanized area (HUa) showed lower richness compared to the lightly urbanized area (LUa) (Mann-Whitney U test: 10.0 ± 3.

Chemical analysis and toxicity of seaweed extracts with inhibitory activity against tropical fruit anthracnose fungi.

Background: Banana and papaya are among the most important crops in the tropics, with a value amounting to millions of dollars per year. However, these fruits suffer significant losses due to anthracnose, a fungal disease. It is well known that certain seaweed extracts possess antifungal activity, but no published data appear to exist on the practical application of this property.
