Recovery of valuable metals from spent lithium-ion batteries using microbial agents for bioleaching: a review

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 14

Published: May 31, 2023

Spent lithium-ion batteries (LIBs) are increasingly generated due to their widespread use for various energy-related applications. LIBs contain several valuable metals including cobalt (Co) and lithium (Li) whose supply cannot be sustained in the long-term view of increased demand. To avoid environmental pollution recover metals, recycling spent is widely explored using different methods. Bioleaching (biohydrometallurgy), an environmentally benign process, receiving attention recent years since it utilizes suitable microorganisms selective leaching Co Li from cost-effective. A comprehensive critical analysis studies on performance microbial agents extraction solid matrix would help development novel practical strategies effective precious LIBs. Specifically, this review focuses current advancements application namely bacteria (e.g.,

Microalgal and Nitrogen-Fixing Bacterial Consortia: From Interaction to Biotechnological Potential

Plants, Journal Year: 2023, Volume and Issue: 12(13), P. 2476 - 2476

Published: June 28, 2023

Microalgae are used in various biotechnological processes, such as biofuel production due to their high biomass yields, agriculture biofertilizers, of high-value-added products, decontamination wastewater, or biological models for carbon sequestration. The number these applications is increasing, and such, any advances that contribute reducing costs increasing economic profitability can have a significant impact. Nitrogen fixing organisms, often called diazotroph, also great potential, mainly an alternative chemical fertilizers. Microbial consortia typically perform more complex tasks than monocultures execute functions challenging even impossible individual strains species. Interestingly, microalgae diazotrophic organisms capable embrace different types symbiotic associations. Certain corals lichens exhibit this relationship nature, which enhances fitness. However, be artificially created laboratory conditions with the objective enhancing some processes each organism carries out independently. As result, utilization garnering interest potential yields biomass, well producing derived products serving purposes. This review makes effort examine associations aim highlighting improving processes.

Heavy Metals Can Affect Plant Morphology and Limit Plant Growth and Photosynthesis Processes

Agronomy, Journal Year: 2023, Volume and Issue: 13(10), P. 2601 - 2601

Published: Oct. 12, 2023

Soil heavy metal pollution caused by human activities has become one of the most critical environmental issues with a global concern. Phytoremediation is widely used due to its low cost and friendliness. However, impact metals on plant growth remains unclear. This study investigated effects photosynthetic activity Picris divaricata Vant. under different cadmium concentrations using hydroponics cultivation system. The results showed that processes P. exhibited phenomenon promotion in Cd inhibition high concentrations. Under medium concentration (≤25 μM), there was no toxicity terms growth, but inhibited growth. Fe content leaves gradually increased as increased; it reached 201.8 mg kg−1 75 μM Cd. significant difference Mn between treatment control (p > 0.05). contents carotenoid ranged 3.06 3.26 mg/g across treatments, showing differences. 5–75 did not directly affect photosynthesis divaricata. Higher reduced stomatal density leaves, resulting mesophyll conductance limitations, indirectly affecting photosynthesis. These research provide reference for evaluating selecting tolerant plants environmentally friendly approaches remediate pollution.
