Environmental DNA (eDNA) is the that can be extracted from an environmental sample, enabling monitoring of whole biological communities across a large number samples, at potentially lower cost, which significantly benefit river conservation. A systematic mapping protocol was designed to investigate use eDNA in rivers, specifically terms research topics, geographic and taxonomic biases, as well information gaps. Furthermore, potential opportunities rivers possible paths find this kind on...

The objective of this study is to understand the functional and metabolic potential microbial communities along Apatlaco River highlight activities related bioremediation its relationship with Apatlaco's pollutants, enhance future design more accurate processes. Water samples were collected at four sampling sites (S1-S4) a whole metagenome shotgun sequencing was performed survey functions for bioremediation. A HMMER search used detect sequence homologs polyethylene terephthalate (PET)...

Abstract Bacterial degradation of crude oil is a promising strategy for reducing the concentration hydrocarbons in contaminated environments. In first part this study, we report enrichment two bacterial consortia from deep sediments Gulf Mexico with as sole carbon and energy source. We conducted comparative analysis community original sediment, assessing its diversity, compared it to observed after exposure defined cultures. The consortium exhibiting highest hydrocarbon was predominantly...

The application of machine learning (ML) techniques stands as a reliable method for aiding in the diagnosis complex diseases. Recent studies have related composition gut microbiota to presence autism spectrum disorder (ASD), but until now, results been mostly contradictory. This work proposes using study microbiome and its role early ASD. We applied support vector machines (SVMs), artificial neural networks (ANNs), random forest (RF) algorithms classify subjects neurotypical (NT) or having...

This paper describes an organosolv pretreatment of corncob waste to improve its anaerobic digestion for biogas production. Through a thermochemical process based on the use ethanol and acetic acid, it was possible separate fractions lignin, considered be natural inhibitor processes. In addition, with this pretreatment, available sugars in carbohydrates present as monosaccharides, or simple sugars, were depolymerised, facilitating process. The obtained results include chemical...

Abstract Due to the rapid expansion of industrial activity, soil pollution has intensified. Plants growing in these polluted areas have developed a rhizobiome uniquely and specially adapted thrive such environments. However, it remains uncertain whether acts as sufficiently selective force shape rhizobiome, adaptations endure over time, potentially aiding long-term phytoremediation. Therefore, present study, we aimed compare microbiome associated with roots from plants germinated riverbanks...

The objectives of this work were first to evaluate the effect coupling a zero-valent side filter anaerobic fluidized bed bioreactors (HFBB) versus without filter, also called methanogenic (MFBB); and second study diversity microbial community in both types bioreactors. At end operation (in last 75 d), HFBB reached 95% removal incoming tetrachloroethylene, whereas MFBBs achieved 88%. Genera such as Dehalobacter spp., Desulfurospirillum Desulfitobacterium Dehalococcoides Methanosarcina found...

The objective of this work was to evaluate the degradation nonionic surfactant Tween 80 by a PCE-degrading consortium anchored in bioparticles fluidized bed bioreactors used onsite remediation. Batch lab-scale were set with dominant denitrifying (DN), methanogenic (M), and aerobic (Ab) metabolisms. at 100 mg/L sole source carbon energy. Denitrifying had highest removal (70%). removals M Ab 53 37%, respectively. Removals organic matter (COD) closely followed efficiencies reported for Tween....

Summary This paper proposes an inverse optimal neural control method of a nonlinear anaerobic bioprocesses model for simultaneous hydrogen and methane production in presence disturbances. Based on the fundamental properties system, passivity approach is designed such that asymptotic stability guaranteed. A recurrent high‐order network unknown systems bounded disturbances parameter uncertainties proposed to identify nonmeasurable state variables which are directly related biofuels production....

Abstract Objectives In order to characterize a river-associated, enriched microbiome capable of degrading an anthraquinone dye from the oil blue family, as well assessing its functional potential, we performed taxa-specific metagenomic deconvolution analysis based on contact probability maps at chromosomal level. This study will allow associating genomic content “ Candidatus Afipia apatlaquensis” strain IBT-C3 with phenotypic potential in context bioremediation textile dyes. We anticipate...

The synthesis nanoparticles was obtained chemical reduction method. material fully characterized by X-ray diffraction, scanning electron microscopy (SEM), energy-dispersive (EDX), transmission specific surface...

Maize forms the basis of Mexican food. As a result, approximately six million tons corncob are produced each year, which represents an environmental issue, as well potential feedstock for biogas production. This research aimed to analyze taxonomic and functional shift in microbiome fermenters using whole metagenome shotgun approach. Two strategies were used understand microbial community at beginning end anaerobic digestion: (i) phylogenetic analysis infer presence coverage clade-specific...
