Morphophysiological Adaptations of Aquatic Macrophytes in Wetland-Based Sewage Treatment Systems: Strategies for Resilience and Efficiency under Environmental Stress.

There is a common misconception that aquatic macrophytes face significant challenges in wetland-based sewage treatment systems. This study aims to correct this perception by focusing on the crucial morphophysiological adaptations of aquatic macrophytes that enable them to thrive in wetland-based sewage treatment systems, particularly under environmental stress. These adaptations are vital for improving the efficiency and resilience of wastewater treatment processes, offering sustainable solutions in the face of variable environmental conditions and complex contaminant mixtures.

Green solutions for antibiotic pollution: Assessing the phytoremediation potential of aquatic macrophytes in wastewater treatment plants.

We compared the ability of one emergent (Sagittaria montevidensis), two floating (Salvinia minima and Lemna gibba), and one heterophyllous species (Myriophyllum aquaticum) to simultaneously remove sulfamethoxazole, sulfadiazine, ciprofloxacin, enrofloxacin, norfloxacin, levofloxacin, oxytetracycline, tetracycline, doxycycline, azithromycin, amoxicillin, and meropenem from wastewater in a mesocosm-scale constructed wetland over 28 days. Antibiotic concentrations in plants and effluent were analyzed using an LC-MS/MS to assess the removal rates and phytoremediation capacities. M.

The phytoremediation capacity of Lemna minor prevents deleterious effects of anti-HIV drugs to nontarget organisms.

We investigated physiological responses of Lemna minor plants and their capacity to remove tenofovir (TNF; 412 ng l), lamivudine (LMV; 5428 ng l) and/or efavirenz (EFV; 4000 ng l) from water through phytoremediation. In addition, the toxicological safety of water contaminated with these drugs after treatment with L. minor plants to photosynthetic microorganisms (Synechococcus elongatus and Chlorococcum infusionum) was evaluated.

Biofixation of Air Emissions and Biomass Valorization-Evaluation of Microalgal Biotechnology.

This research appraised the simultaneous biofixation, that is not quite common in scientific literature, of carbon dioxide (CO) and nitric oxides (NO) by microalgae species Chlorella vulgaris, Haematococcus pluvialis, and Scenedesmus subspicatus. The experimental design was established by five treatments with gas concentrations between control-0.04% of CO, 5 to 15% of CO, and 30 to 100 ppm of NOx.

Effects of oil contamination on plant growth and development: a review.

Oil spills generate several environmental impacts and have become more common with the increase in petroleum extraction, refining, transportation, and trade. In soil, oil contamination increases water and nutrient availability and compaction, directly affecting plant growth and development. Different aspects of phytotoxicity can be observed and will vary according to the characteristics of soil and plants.

Petroleum-Tolerant Rhizospheric Bacteria: Isolation, Characterization and Bioremediation Potential.

Petroleum is an important energy source. Due to its intensive exploration, accidents resulting in oil spills on soil are frequent, which creates consequences to ecosystems and human health. Rhizodegradation is an efficient technique that promotes the decontamination of polluted environments through the selection and use of rhizosphere microorganisms from phytoremediation plants.

Rhizospheric microorganisms as a solution for the recovery of soils contaminated by petroleum: A review.

Petroleum is currently the world's main energy source, and its demand is expected to increase in coming years. Its intense exploitation can lead to an increase in the number of environmental accidents, such as spills and leaks, and an increase in the generation of environmental liabilities resulting from refining. Due to its hydrophobic characteristics and slow process of biodegradation, petroleum can remain in the environment for a long time and its toxicity can cause a negative impact on both terrestrial and aquatic ecosystems, with the main negative effects related to its carcinogenic potential for both animals and humans.

Effectiveness of Persea major Kopp (Lauraceae) extract against Enterococcus faecalis: a preliminary in vitro study.

Background: Persea major Kopp (Lauraceae) is a plant with wound healing, antibacterial, and analgesic properties. The aim of this study was to assess the in vitro antibacterial activity of the concentrated crude extract (CCE) and ethyl acetate fraction (EAF) of this plant against Enterococcus faecalis and compare it with calcium hydroxide [Ca(OH)] paste and 2% chlorhexidine digluconate (CHX).

Methods: The plant material was collected, and an extract was prepared according to the requirements of the study (CCE and EAF).

Dissolved heavy metal determination and ecotoxicological assessment: a case study of the corumbataí river (são paulo, Brazil).

The aim of this one-year study (August 2009 to July 2010) was to evaluate the Corumbataí River water polluted by anthropogenic sources and see how it affects the reproduction of the microcrustacean Ceriodaphnia dubia (Richard, 1984) in laboratory conditions over seven days of exposure to water samples collected monthly at six different locations. We determined the concentrations of zinc (Zn), copper (Cu), nickel (Ni), lead (Pb), and cadmium (Cd), as well as physicochemical parameters such as dissolved oxygen, conductivity, water temperature, and pH. Dissolved oxygen and conductivity demonstrated anthropogenic influence, as dissolved oxygen concentration decreased and conductivity increased from the upstream to the downstream stretch of the river.

Restoration of polluted waters by phytoremediation using Myriophyllum aquaticum (Vell.) Verdc., Haloragaceae.

The present study assessed the reduction of nutrients and organic matter in polluted waters using Myriophyllum aquaticum. Twelve experimental groups were established and distributed in six control groups (CG) and six plant treated groups (PTG). The following analyses were performed in three sampling sets and measured every three days: chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammoniacal nitrogen (AN), organic nitrogen (ON), total Kjeldahl nitrogen (TKN), and total phosphorus (TP).
