ABSTRACT The effect of cadmium (Cd) on root exudates sorghum and maize was investigated in order to get further insight into the mechanisms plant tolerance Cd. Plants were grown hydroponically supplemented with: 0, 0.5, 5.0 mg Cd L− 1. Hydroponic solutions containing analyzed by high performance liquid chromatography (HPLC). results showed different exudation patterns with supply. While enhanced malate over entire range applied uptake solutions, increased mainly citrate. Moreover,...
SUMMARY Laboratory-raised mice live approximately seven times longer and healthier lives compared to their wild counterparts, due a standardized healthy diet limited exposure environmental stressors 1 . Aging is associated with increased inflammation microbial dysbiosis 2–4 Collectively, these influence microbiota evolution may contribute the enrichment in pathobiont frequency observed old age 4 Alternatively, this increase could stem from decline colonization resistance 5,6 , creating...
Microalgae are valuable sources of bioactive compounds. However, their production requires strategies to enhance metabolic responses. This study explores how Chlorella vulgaris responds different salinity conditions using a two-stage cultivation strategy, assessing the change in amino acid and carotenoid content on microalgae over time. First, were cultivated under optimal conditions, followed by exposure levels (150 mM 300 NaCl). Growth kinetics, nutrient uptake, biochemical composition...
Biosorbents have been recently gaining importance, with an increasing number of publications on their environmental applications, especially for removal organic pollutants from aqueous media. The aim this work was to evaluate the sorption capacity a biosorbent, namely granulated cork, remove mixtures ibuprofen (IB), carbamazepine (CB) and clofibric acid (CA) water wastewater. High efficiencies were attained IB CB while less satisfactory performance observed CA. Simultaneous three compounds...
Abstract Several studies on phytotoxic effects caused by organic xenobiotics and their removal from water macrophytes have already been performed to evaluate the usefulness of these plants for phytoremediation technologies. In this context, a study was conducted assess Typha spp.'s ability withstand remove, water, non-steroidal anti-inflammatory drug ibuprofen. For an initial ibuprofen concentration 20 µg L−1, removed nearly 60% it within first 24 h, attaining over 99% end assay (21 days)....
Overuse of pesticides has resulted in environmental problems, threating public health through accumulation food chains. Phytoremediation is a powerful technique to clean up contaminated environments. However, it necessary unravel the metabolic mechanisms underlying phytoremediation order increase efficiency this process. Therefore, growth, physiological and biochemical responses leaves roots Solanum nigrum L. exposed commonly used fungicide metalaxyl were investigated. This species shows...
Abstract Microcosm constructed wetland systems established with a matrix of light expanded clay aggregates (LECA) and Typha spp. or Phragmites australis were used to evaluate their ability remove atenolol from wastewater. Combined an efficient SPE concentration step, the use HPLC-DAD yielded analytical method for quantification very low LOQ (9 ng mL−1) high reproducibility (RSD < 4%). Overall removal efficiencies 92.5% 94.5% achieved after retention time only 4 days microcosm planted spp.,...
Remediation of sites contaminated with heavy metals using hyperaccumulators seems a promising alternative to engineering approaches. In this work, we compared cadmium (Cd) accumulation and tolerance (based on responses oxidative stress) in three different species, Brassica juncea (L.) Czern, Nicotiana tabacum L. Solanum nigrum L., described the literature as very tolerant or even hyperaccumulators. The plants were grown soil spiked Cd concentrations (0 – 35 mg kg−1) over period 90 days....
In acidic soils with manganese (Mn) toxicity, arbuscular mycorrhizal fungi (AMF) can improve plant host growth by enhancing nutrition and protecting against environmental stress. The intact extraradical mycelium (ERM) of AMF is able to survive Mediterranean summer conditions provide an earlier colonization winter crops. This study evaluated if season hindered the beneficial effects wheat ERM associated a native plant, in soil. Wheat was grown soil or disrupted Ornithopus compressus (ORN),...
