Fitorremediación de efluentes acuícolas mediante el uso de seis microalgas marinas: aportes de sustentabilidad en la industria acuícola del erizo de mar en Argentina

Rev. biol. trop; 72 (supl.1), 2024
Resumen Introducción: La industria acuícola está en constante crecimiento, registrando una producción mundial de casi 88 millones de toneladas para el año 2020. Esta industria trae consigo problemas ambientales si sus efluentes no son debidamente tratados. En el 2020, se constituyó la primera emp...

Amazonian soil fungi are efficient degraders of glyphosate herbicide; novel isolates of Penicillium, Aspergillus, and Trichoderma

Braz. j. biol; 83 (), 2023
Abstract Pesticide residues that contaminate the environment circulate within the hydrological cycle can accumulate within the food chain and cause problems to both environmental and human health. Microbes, however, are well known for their metabolic versatility and the ability to degrade chemically stab...

Isolation and screening of chromium resistant bacteria from industrial waste for bioremediation purposes

Braz. j. biol; 83 (), 2023
Abstract Chromium (VI) a highly toxic metal, a major constituent of industrial waste. It is continuously release in soil and water, causes environmental and health related issues, which is increasing public concern in developing countries like Pakistan. The basic aim of this study was isolation and scree...

Effects of homeopathic preparations on raphidiopsis raciborskii (Cyanobacteria) toxicity in artemia salina mode

Cyanobacteria are microorganisms found in different parts of the world. Some genera are cyanotoxins producers a sodium channel blockingneurotoxin (saxitoxins). Some homeopathic preparations have been identified as remedial action on toxicity models in Artemia salina. This stud...

Nitrogen and carbon metabolism evaluation in paricá plants subjected to different cadmium concentrations

Biosci. j. (Online); 38 (), 2022
The development of anthropogenic activities such as industry, mining, agriculture, urban waste discard has been, the main actions that result in increased contamination by heavy metals in soil, water and air. One of the most harmful metals made available by these activities is cadmium, and even at low co...

Biodegradation of petroleum by bacteria isolated from fishes of Indian Ocean

Braz. j. biol; 82 (), 2022
In this study, oil degrading bacteria discovered from fish living near the oil ports at Karachi in Pakistan were characterized. The bacteria isolated from skin, gills, and gut in fish could consume crude oil as a source of carbon and energy. Total 36 isolates were tested using Nutrient Agar (NA) and MSA ...

Decolorization of the benzidine-based azo dye Congo red by the new strain Shewanella xiamenensis G5-03

Braz. j. biol; 82 (), 2022
Shewanella xiamenensis G5-03 was observed to decolorize the azo dye Congo red in synthetic wastewater. The influence of some factors on the dye decolorization efficiency was evaluated. The optimal decolorization conditions were temperature 30-35 °C, pH 10.0, incubation time 10 h, and static condition. T...

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...

Cytotoxicity and the bioconversion strategy of Aristolochia spp

Arq. Inst. Biol; 88 (), 2021
Aristolochia plants are notable from an ethnopharmacological viewpoint, but the relevance of these species for medicinal purposes has been debated because of their inherent toxicity. The convergence of these contrasting realities can be readily achieved using bioconversion methods, which have been shown ...
