Biodiesel production and simultaneous treatment of domestic and livestock wastewater using indigenous microalgae, Chlorella sorokiniana JD1-1

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Sept. 14, 2023

Abstract In this study, the potential of Chlorella sorokiniana JD1-1 for biodiesel production was evaluated using domestic wastewater (DWW) as a diluent locally-generated livestock (LWW). This strategy aimed to provide sustainable treatment, reduce environmental impacts, enhance cost-effectiveness, and promote production. LWW diluted with tap water DWW at ratios 75%, 50%, 25% (v/v), effects on microalgal growth, nutrient removal efficiency, lipid yield were evaluated. Although maximum biomass concentration observed in artificial growth medium (BG-11) (1170 mg L −1 ), 75% dilution (610 ) (780 yielded results comparable exclusive use (820 suggesting substitution. Total nitrogen (TN) rates consistently high under all conditions, particularly samples higher concentrations LWW. Conversely, total phosphorus (TP) decreased most although some displayed large increases. Further studies are necessary optimize balance while maintaining economic feasibility maximizing

Dynamic Characteristics and Environmental Driving Factors of Phytoplankton Communities in Plateau Rivers: The Case of the Lhasa River

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 283 - 283

Published: Jan. 20, 2025

The dynamic changes in plateau river ecosystems and the driving mechanisms of environmental factors have garnered significant attention. Phytoplankton, a core component aquatic ecosystems, can directly reflect environment. This study focuses on phytoplankton Lhasa River Basin, including riverbed from source to mouth, five largest tributaries, two adjacent wetlands. We analyzed spatial temporal variation characteristics explored based four field surveys conducted between September 2019 March 2021. Results showed that total 127 species six algal phyla were identified, Cyanobacteria. Among these, Bacillariophyta was dominant group, accounting for 41.7% identified species. Spatially, diversity decreasing trend upstream downstream while temporally peaking spring autumn. Redundancy analysis revealed driven by hardness altitude, midstream pH potassium ions, nitrate ammonium nitrogen. Classification regression tree hardness, magnesium nitrite key influencing abundance, diversity, evenness. highlights ecological dynamics communities River, demonstrating their high sensitivity factors. These findings could help establish as critical indicators ecosystem health provide scientific guidance conservation management ecosystems.

Enantioselectivity in ecotoxicity of pharmaceuticals, illicit drugs, and industrial persistent pollutants in aquatic and terrestrial environments: A review

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 912, P. 169573 - 169573

Published: Dec. 25, 2023

At present, there is a serious concern about the alarming number of recalcitrant contaminants that can negatively affect biodiversity threatening ecological status marine, estuarine, freshwater, and terrestrial ecosystems (e.g., agricultural soils forests). Contaminants emerging (CEC) such as pharmaceuticals (PHAR), illicit drugs (ID), industrial persistent pollutants, polychlorinated biphenyls (PCBs) polybrominated diphenyl ethers (PBDEs) chiral ionic solvents are globally spread potentially toxic to non-target organisms. More than half these have been measured at different enantiomeric proportions in diverse ecosystems. Enantiomers exhibit toxicodynamics toxicokinetics, thus, cause effects. Therefore, distribution occurrence cannot be neglected toxicity other adverse biological effects expected enantioselective. Hence, this review aims reinforce recognition stereochemistry environmental risk assessment (ERA) CEC gather up-to-date information current knowledge regarding enantioselectivity ecotoxicity PHAR, ID, pollutants (PCBs PBDEs) present freshwater soil We performed an online literature search obtain state-of-the-art research enantioselective studies available for assessing impact classes CEC.

The use of zero-carbon and carbon-neutral fuels reduces emissions conventional pollutants, but their can be toxic have various adverse effects on human health. This article reviews the possible combustion products fuels, as well cytotoxic potential health risks. At same time, review outlines biological models toxicity detection methods commonly used in pollutant studies. Metals, nitrogen oxides (NOX), ammonia (NH3) emitted from metal hydrogen are harmful to Exhaust particularly biodiesel, blends with gasoline/diesel cytotoxic, leading severe cellular damage, such oxidative inflammatory responses, DNA cell death, or apoptosis. Moreover, normal function body’s respiratory, cardiovascular, immune, digestive, urinary, nervous systems may also impacted by these fuel according research. Cytotoxicity is usually related type, dose, line experiment. provides some ideas for exhaust emission management assessment. It presents a theoretical experimental basis further research, including vivo experiments.
