Microalgae: A potential bioagent for treatment of emerging contaminants from domestic wastewater

Chemosphere, Год журнала: 2024, Номер 351, С. 141245 - 141245

Опубликована: Янв. 21, 2024

Water crisis around the world leads to a growing interest in emerging contaminants (ECs) that can affect human health and environment. Research showed thousands of compounds from domestic consumers, such as endocrine disrupting chemicals (EDCs), personal care products (PCPs), pharmaceuticals active (PhAcs), could be found wastewater concentration mostly ng L−1 μg L−1. However, generally, treatment plants (WWTPs) are not designed remove these ECs their discharge levels. Scientists looking for economically feasible biotreatment options enabling complete removal before discharge. Microalgae cultivation is likely approach removing simultaneously any residual organic nutrients. Microalgal growth rate efficiency affected by various factors, including light intensity, CO2 addition, presence different nutrients, etc., parameters greatly help make microalgae more efficient. Furthermore, algal biomass harvests repurposed produce bulk sustainable aviation fuel, biofuel, bioplastic, biochar; this significantly enhance economic viability. Therefore, review summarizes microalgae-based bioprocess mechanisms wastewaters highlights strategies improve efficiency. shows role profile relevance using ECs-treated green products, well challenges future research recommendations.

A review on microbes mediated resource recovery and bioplastic (polyhydroxyalkanoates) production from wastewater

Microbial Cell Factories, Год журнала: 2024, Номер 23(1)

Опубликована: Июль 1, 2024

Abstract Background Plastic is widely utilized in packaging, frameworks, and as coverings material. Its overconsumption slow degradation, pose threats to ecosystems due its toxic effects. While polyhydroxyalkanoates (PHA) offer a sustainable alternative petroleum-based plastics, their production costs present significant obstacles global adoption. On the other side, multitude of household industrial activities generate substantial volumes wastewater containing both organic inorganic contaminants. This not only poses threat but also presents opportunities get benefits from circular economy. Main body abstract Production bioplastics may be improved by using nutrients minerals feedstock for microbial fermentation. Strategies like feast-famine culture, mixed-consortia integrated processes have been developed PHA highly polluted with high loads. Various process parameters loading rate, content (volatile fatty acids), dissolved oxygen, operating pH, temperature critical roles accumulation biomass. Research advances are going on downstream recovery utilizing combination physical chemical (halogenated solvents, surfactants, green solvents) methods. review highlights recent developments upcycling resources into PHA, encompassing various strategies, processing methodologies, techno-economic analyses. Short conclusion Organic carbon nitrogen promising, cost-effective source producing bioplastic. Previous attempts focused enhancing productivity through optimizing culture systems growth conditions. However, despite technological progress, challenges persist, such low productivity, intricate processing, scalability issues, properties resulting PHA. Graphical
