Metagenomic and Metatranscriptomic Study of Microbial Metal Resistance in an Acidic Pit Lake

Microorganisms, 2020
Cueva de la Mora (CM) is an acidic, meromictic pit lake in the Iberian Pyrite Belt characterized by extremely high metal(loid) concentrations and strong gradients in oxygen, metal, and nutrient concentrations.

Characterization and genomic analysis of two novel psychrotolerant Acidithiobacillus ferrooxidans strains from polar and subpolar environments

Frontiers in Microbiology, 2022
The bioleaching process is carried out by aerobic acidophilic iron-oxidizing bacteria that are mainly mesophilic or moderately thermophilic. However, many mining sites are located in areas where the mean temperature is lower than the optimal growth ...

Response Surface Methodology (RSM) for analysing culture conditions of Acidocella facilis strain USBA-GBX-505 and Partial Purification and Biochemical Characterization of Lipase 505 LIP

Universitas Scientiarum, 2017
Using Response Surface Methodology (RSM) we evaluated the culture conditions (nitrogen source, carbon source, pH and agitation rate) that increase the biomass of Acidocella facilis strain USBA-GBX-505 and therefore enhance the production of its lipolytic

Low‐Dose Chlorothalonil Induces Testicular Injury Through Disruption of Steroidogenic Signaling in Adult Male Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chlorothalonil (CHL) is a widely used organochlorine fungicide frequently detected in environmental and food matrices. Although increasing evidence indicates adverse effects in nontarget species, the mechanisms underlying CHL‐induced male reproductive toxicity remain incompletely understood.

Possible Role of CHAD Proteins in Copper Resistance

Microorganisms
Conserved Histidine Alpha-helical Domain (CHAD) proteins attached to the surface of polyphosphate (PolyP) have been studied in some bacteria and one archaeon. However, the activity of CHAD proteins is unknown beyond their interaction with PolyP granules.

Biochemical testing and pathology reveal rare cause of pediatric acute liver failure: Hyperornithinemia‐hyperammonemia‐homocitrullinuria syndrome

JPGN Reports, EarlyView.
Abstract Hyperornithinemia‐hyperammonemia‐homocitrullinuria (HHH) syndrome is a rare metabolic condition that can cause lethargy, ataxia, tachypnea, nausea, vomiting, seizures, coma, and acute liver failure. We present a 26‐month‐old female with acute liver failure who was diagnosed with HHH 1 week after admission. Histology revealed an acute hepatitic

Biogeographical distribution of acidophiles and their effects around the Zijinshan heap bioleaching plant

, 2015
The Zijin heap bioleaching plant began operation near the end of 2005, and over 4 years of operation, concerns rose about the migration of acidophiles outside of the heap due to the proximity of the Ting River.

Investigation of the microbial diversity of an extremely acidic, metal-rich water body (Lake Robule, Bor, Serbia) [PDF]

Journal of the Serbian Chemical Society, 2014
An investigation of the microbial diversity of the extremely acidic, metal-rich Lake Robule was carried out using culture-dependant and culture-independent (T-RFLP) methods, and the ability of indigenous bacteria from the lake water to leach ...

Do good neighbours compensate for bad climate? The case of sessile oak Quercus petraea in phylogenetically distant neighbourhoods

Oikos, EarlyView.
Stressful climates threaten the performance of individuals and the survival of species, but individual performance also depends on biotic interactions with neighbours, so that ‘good' neighbours might in theory compensate for ‘bad' climates. However, what makes a good neighbour, and why, has been little studied.
