Insights Into Earthworms and Fungi: Pioneering Roles in Mitigating Global Food Scarcity and Combatting Land Degradation

Land Degradation and Development, Год журнала: 2025, Номер unknown

Опубликована: Янв. 9, 2025

ABSTRACT Climate change significantly impacts terrestrial ecosystems by altering soil moisture, temperature regimes, rainfall patterns, and frequency of extreme weather events. These disruptions lead to shifts in community structures, accelerates land degradation processes, which turn exacerbate the global food crisis. This review explores roles earthworms fungi improving health mitigating insecurity through their contributions nutrient cycling, fertility, plant growth. Earthworms recognized as key biological agents structures enhancement, carbon sequestration. They play crucial heavy metal remediation, quality, fostering sustainable agricultural practices such organic farming. The emphasizes influence on dynamics, particularly response residues management, characteristics, field conditions. Earthworm activity positively affects microbial communities, growth, even under stress factors like contamination extremes. Review identifies research gaps understanding earthworm distribution, performance, capacity for remediation varied agro‐ecological contexts. In addition biotic factors, present also examines alternative habits superfoods strategies address zero hunger, aligning with United Nations Sustainable Development Goals (SDGs) poverty eradication, improved health, overall well‐being. By incorporating into systems addressing critical needs, there is significant potential mitigate contribute alleviation crises.

Benefits of Immobilized Bacteria in Bioremediation of Sites Contaminated with Toxic Organic Compounds

Microorganisms, Год журнала: 2025, Номер 13(1), С. 155 - 155

Опубликована: Янв. 14, 2025

Although bioremediation is considered the most environmentally friendly and sustainable technique for remediating contaminated soil water, it effective when combined with physicochemical methods, which allow preliminary removal of large quantities pollutants. This allows microorganisms to efficiently eliminate remaining contaminants. In addition requiring necessary genes degradation pathways specific substrates, as well tolerance adverse environmental conditions, may perform below expectations. One typical reason this high toxicity xenobiotics present in concentrations, stemming from vulnerability bacteria introduced a site. especially true planktonic bacteria, whereas within biofilms or microcolonies have significant advantages over their counterparts. A physical matrix essential formation, maintenance, survival bacterial biofilms. By providing such immobilization, formation can be facilitated accelerated. Therefore, immobilization offers comprehensive solution cleanup by harnessing specialized metabolic activities while ensuring retention efficacy at target sites. many cases, also need methods that are otherwise required initially reduce contaminant concentrations. Then, will possible use remediation higher concentrations xenobiotics, significantly reducing costs maintaining rapid rate processes. review explores benefits highlighting materials processes developing an optimal matrix. It focuses on following four key areas: (i) types organic pollutants impacting human health, (ii) strains used processes, (iii) (iv) cells various carriers targeted pollutant degradation.

Biosurfactants-based mixed polycyclic aromatic hydrocarbon degradation: From microbial community structure toward non-targeted metabolomic profile determination

Environment International, Год журнала: 2024, Номер 184, С. 108448 - 108448

Опубликована: Янв. 18, 2024

Biosurfactants-based bioremediation is considered an efficient technology to eliminate environmental pollutants including polycyclic aromatic hydrocarbons (PAHs). However, the precise role of rhamnolipids or lipopeptide-biosurfactants in mixed PAH dissipation, shaping microbial community structure, and influencing metabolomic profile remained unclear. In this study, results showed that maximum degradation was achieved lipopeptide-assisted treatment (SPS), where pyrene phenanthrene were substantially degraded up 74.28% 63.05% respectively, as compared (SPR) un-aided biosurfactants (SP). Furthermore, high throughput sequencing analysis revealed a significant change PAH-degrading community, with Proteobacteria being predominant phylum (>98%) followed by Bacteroidota Firmicutes all treatments. Moreover, Pseudomonas Pannonibacter found highly potent bacterial genera for SPR, SPS, SP treatments, nevertheless, abundance genus significantly enhanced (>97%) SPR groups. On other hand, non-targeted through UHPLC-MS/MS exhibited remarkable metabolites amino acids, carbohydrates, lipid metabolisms input whereas, intensities (more than two-fold) observed treatment. The findings study suggested aforementioned can play indispensable well seek offer new insights into shifts communities their metabolic function, which guide development more targeted strategies complete removal organic such from contaminated environment.

Assessing the feasibility and sustainability of a surfactin production process: a techno-economic and environmental analysis

Environmental Science and Pollution Research, Год журнала: 2024, Номер unknown

Опубликована: Апрель 9, 2024

Abstract Biosurfactants have been profiled as a sustainable replacement for chemical-based surfactants since these bio-based molecules higher biodegradability. Few research papers focused on assessing biosurfactant production to elucidate potential bottlenecks. This aims assess the techno-economic and environmental performance of surfactin in scale 65m 3 , considering different product yields involving European energy crisis 2021–2022. The conceptual design, simulation, techno-economic, assessments were done by applying process engineering concepts software tools such Aspen Plus v.9.0 SimaPro v.8.3.3. results demonstrated high economic values market offset low fermentation yields, recovery efficiency, capital investment. sensitivity analysis assessment elucidated minimum selling price between 29 31 USD/kg surfactin, while processing feasibility 4 5 kg/h is needed reach an equilibrium point. must be improved carbon footprint was 43 kg CO 2 eq/kg surfactin. downstream demand are main bottlenecks aspects contribute 63 25% total emissions. key factors future optimization research.
