Abstract High‐throughput sequencing has the potential to describe biological communities with high efficiency yet comprehensive assessment of diversity species‐level resolution remains one most challenging aspects metabarcoding studies. We investigated utility curated ribosomal and mitochondrial nematode reference sequence databases for determining phylum‐specific clustering thresholds. compiled 438 290 sequences which identified 99% 94% as species delineation threshold, respectively. These...

Abstract Endophytic fungus Penicillium crustosum EP-1 was used to create spherical shape magnesium oxide nanoparticles (MgO-NPs). The MgO-NPs possess a crystalline structure with sizes of 8–35 nm. weight percentages Mg and O were 42.44% 30.13%, respectively, as shown in energy-dispersive X-ray analysis. In addition, analysis involving dynamic light scattering indicated the uniformity within colloidal solution. These NPs displayed polydispersity index 0.341 held surface charge −29.7 mV. A...

Heavy metals cause deleterious effects on human health and drastically alter the biogeochemical cycles within freshwater habitats. The main activities leading to heavy metal contamination of various aquatic ecosystems comprise industry, agriculture, urbanization, transport mining. Lake Nasser is source in Egypt, usually polluted from upstream hydrographic basin River Nile. current study surveyed impact (i.e., Cd, Zn, Pb Cu) water, sediment two Nile Tilapia (Oreochromis niloticus) fish organs...

Background P. aeruginosa , a significant bacterium, can cause severe illness and resistance to antibiotics. Quorum sensing (QS) systems regulate virulence factors production. Targeting QS could reduce bacteria pathogenicity prevent antibiotic resistance. Cruciferous vegetables contain sulforaphane, known for its anti-inflammatory, antioxidant, anticancer, antimicrobial properties. Aim We aimed examine the inhibitory influences of at sub-inhibitory concentration (¼ minimum concentration,...

The problem of antibiotic resistance is a global critical public health concern. In light the threat returning to pre-antibiotic era, new alternative approaches are required such as quorum-sensing (QS) disruption and virulence inhibition, both which apply no discernible selective pressure on bacteria, therefore mitigating potential for development resistant strains. Bearing in mind significant role QS orchestrating bacterial virulence, disrupting becomes essential effectively diminishing...

In the historical context of evolution water sources, from wells, rivers and lakes to construction filtration treatment plants starting 19th century, concept “clean water” has acquired a precise definition, based on parameters such as pH, redox potential salinity. Today, public authorities consider drinking safe when it meets strictly defined standards for human consumption. Starting this framework, study aims analyze quality wells in rural area northwestern Romania, where they represent...

In the current research, we examined effects of warfarin (W1 = 5 mg/L and W2 25 mg/L) tinzaparin (T1 T2 on meiofauna using microcosms. These microcosms were intentionally contaminated with both anticoagulants for one month. The findings indicated that nematodes amphipods demonstrated greatest resistance to two evaluated. Specifically, number increased after exposure treatment included T2. Following separate introduction each drug, displayed a taxonomic restructuring, more significant impact...

Dibetou wood sawdust, SEM and IRTF characterized, collected from a local sawmill, was used in its raw chemically activated forms using nitric acid sodium hydroxide to retain Pb2+ ions, according several parameters (pH, contact time, initial metal concentration, mass of adsorbent temperature the medium). The results obtained reveal that removal rate ions on sawdust reached percentage about 84% 93% successively. experimental design methodology full factorial has enabled us study check...
