Arbuscular mycorrhizal fungi activity in the rhizosphere of tree seedlings subjected to residual herbicides

Braz. j. biol; 83 (), 2023
Abstract Trees occurring on the margins of agricultural areas can mitigate damage from residual herbicides. Rhizospheric microbial activity associated with trees is one of the main remedial capacity indicators. The objective of this study was to evaluate the rhizospheric microbiological activity in tree ...

Assessment of zinc solubilization potential of zinc-resistant Pseudomonas oleovorans strain ZSB13 isolated from contaminated soil

Braz. j. biol; 83 (), 2023
Abstract Zinc is an essential micronutrient that is required for optimum plant growth. It is present in soil in insoluble forms. Bacterial solubilization of soil unavailable form of Zn into available form, is an emerging approach to alleviate the Zn deficiency for plants and human beings. Zinc solubilizi...

The impact of cow dung augmentation on soil restoration and bio-accumulation of metals (Lead and Cadmium) in Pheretima posthuma (Annelida: Clitellata)

Braz. j. biol; 83 (), 2023
Abstract To investigate the role of cow dung in soil reclamation and bio assimilation along with bio accumulation of heavy metals in earthworm (P. posthuma) (N=900) earthworms were used and treatment groups of CD-soil mixture of different proportion of cow dung were designed. Nonlethal doses of lead acet...

Leaching of saflufenacil in soils with different organic matter contents

Biosci. j. (Online); 38 (), 2022
Saflufenacil is a herbicide recommended for use in the main agricultural crops in Brazil to control eudicotyledonous weeds. However, the application of saflufenacil has been carried out without previous knowledge of this herbicide interactions with soil colloids, which may increase environmental contamin...

Effects of combined treatment of cadmium and oxytetracycline on the terrestrial isopod Porcellio leavis

Braz. j. biol; 82 (), 2022
The influence of pharmaceutical residues and heavy metals on living organisms has received global attention. The present study assessed the interactive effect of antibiotic residues and heavy metals in soil, as contaminated food with cadmium (Cd) and oxytetracycline (OTC) on the isopod Porcellio leavis. ...

A Physiological behavior and tolerance of Lactuca sativa to lead nitrate and silver nitrate heavy metals

Braz. j. biol; 82 (), 2022
This study goal to evaluate the effects of different concentrations of lead (Pb) and silver (Ag) on germination, initial growth and anatomical alterations of Lactuca sativa L. Plants use various mechanisms to reduce the impacts caused by anthropic action, such as xenobiotic elements of soils and water co...

Effects of sheep manure in agricultural soils on the behavior of Folsomia candida and initial growth and development of Avena sativa

Braz. j. biol; 81 (4), 2021
Abstract The aim of this study was to evaluate the effects of sheep manure in agricultural soils on the behavior of Folsomia candida and initial growth and development of Avena sativa. For this, an Oxisol was submitted to different doses of sheep manure and was subsequently evaluated for Folsomia candida...

Assessment of cadmium tolerance and biosorptive potential of Bacillus Cereus GCFSD01 isolated from cadmium contaminated soil

Braz. j. biol; 81 (2), 2021
Continuous occurrence of heavy metals is a major cause of environmental pollution due to its toxic effects. At minimum concentrations, these metals are highly reactive and can gather in the food chains and food web, causing major dangers to public health concerns. Soil samples were collected from Paharan...

Infección por uncinarias en un lactante menor: Reporte de caso
Infantile hookworm infection: Clinical case report

VozAndes; 31 (1), 2020
La uncinariasis es endémica en zonas tropicales. Es común en preescolares y escolares pero infrecuente en lactantes antes de los 6 meses debido al mecanismo de transmisión que implica contacto de la piel con el suelo contaminado. La infección se caracteriza por anemia ferropénica secundaria a sangra...

Bacterial community structure in soils contaminated with electronic waste pollutants from Delhi NCR, India

Background: Microbial community analysis of electronic waste (e-waste)-polluted environments is of interest to understand the effect of toxic e-waste pollutants on the soil microbial community and to evaluate novel microorganisms resisting the toxic environment. The present study aims to investigate the ...
