Chromium (VI) Inhibition of Low pH Bioleaching of Limonitic Nickel-Cobalt Ore

Frontiers in Microbiology, 2022
Limonitic layers of the regolith, which are often stockpiled as waste materials at laterite mines, commonly contain significant concentrations of valuable base metals, such as nickel, cobalt, and manganese.

Microenvironment‐Responsive Nanomedicine Enables Vertical Modulation of Mitochondrial Pathological Networks in Myocardial Ischemia–Reperfusion Injury

Advanced Science, EarlyView.
A mitochondria‐targeted, microenvironment‐responsive nanoplatform enables pH/ROS‐triggered co‐delivery of berberine and isoliensinine to orchestrate ROS scavenging, inflammation suppression, and apoptosis inhibition. This vertical modulation of mitochondrial pathological networks preserves mitochondrial function and effectively mitigates myocardial ...

Río Tinto: A Geochemical and Mineralogical Terrestrial Analogue of Mars

Life, 2014
The geomicrobiological characterization of the water column and sediments of Río Tinto (Huelva, Southwestern Spain) have proven the importance of the iron and the sulfur cycles, not only in generating the extreme conditions of the habitat (low pH, high ...

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 ...

Asking the 5 W's for designing next‐generation bioprocessing

AIChE Journal, EarlyView.
Abstract Biotechnology is expanding beyond traditional, centralized fermentation and toward next‐generation bioprocessing paradigms that emphasize flexible deployment outside the laboratory with application‐specific performance. However, many bioprocesses fail to translate beyond proof‐of‐concept into industrially viable systems because early design ...

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

Male reproductive system in stenopodidean shrimps: Unveiling basal reproductive traits in shrimp‐like Pleocyemata (Stenopodidae and Spongicolidae)

The Anatomical Record, EarlyView.
Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...

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.

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

Chemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.
