Cement Composites Biodeterioration by Acidithiobacillus Thiooxidans

WSEAS TRANSACTIONS ON ENVIRONMENT AND DEVELOPMENT
The focus of this work was to study the biodeterioration of special cement composites by sulfur-oxidizing bacteria Acidithiobacillus thiooxidans. The laboratory prepared cement composites that contained the selected additives - silica fume (a secondary raw material) and zeolite (a natural raw material), as partial replacements for the binder. The tests

Oxygen In The Mix: Is Oxic Microbial Electrosynthesis A Potential Alternative For Biomass Production?

ChemElectroChem, Volume 11, Issue 20, October 16, 2024.
Oxic microbial electrosynthesis (oMES) enables the conversion of renewable electricity and oxic industrial CO2‐streams into biomass by cultivating aerobic, autotrophic hydrogen‐oxidizing bacteria. This article presents the most promising candidates for oMES, discusses their biomass productivity and energy efficiency, and outlines research gaps to bring

Deciphering microbial communities involved in marine steel corrosion using high‐throughput amplicon sequencing

Environmental Microbiology Reports, Volume 16, Issue 4, August 2024.
Aggressive forms of intertidal steel corrosion are shown to involve complex microbial consortia including sulfate‐reducing, sulfide‐oxidizing and iron‐oxidizing bacteria along with others including electroactive microbes. Statistical analysis shows the populations are derived from local bed sediment, indicating sediment anoxia as a risk factor for ...

Small‐scale and scale‐up bioleaching of Li, Co, Ni and Mn from spent lithium‐ion batteries

Journal of Chemical Technology &Biotechnology, Volume 99, Issue 5, Page 1069-1082, May 2024.
Abstract BACKGROUND A bioleaching process could offer the advantage of higher metal recovery in a sustainable manner even from lithium‐ion battery (LIB) samples with very low metal concentrations. In recent years, there has been a significant increase in the use of secondary resources such as LIBs for various purposes including transportation, large ...

Biosynthesized Metallic and Bimetallic Nanoparticles as Effective Biocides for Plant Protection: Plausible Mechanisms and Challenges

Journal of Chemistry, Volume 2024, Issue 1, 2024.
The use of biosynthesized metallic and bimetallic nanoparticles (NPs) as biocides for plant protection has gained significant attention in recent years due to their potential for sustainable and ecofriendly crop protection. In this review article, we discussed the biosynthesis of metallic and bimetallic NPs using various biological sources such as ...

Synthetically Modified Tara and Oak Gall Nut Tannin‐Based Corrosion Inhibitors for Combating the Corrosive Influence of Acidithiobacillus thiooxidans on Mild Steel

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
Natural tara and oak gall nut tannins, which lack corrosion inhibitive properties, were modified using gum arabic and tested against microbial corrosion induced by Acidithiobacillus thiooxidans under isothermal condition (28°C). Mild steel coated with the modified tannins was exposed to the causative under aerobic and anaerobic conditions. Based on the

Plant Growth Promoting Rhizobacteria (PGPR): Reports on Their Colonization, Beneficial Activities, and Use as Bioinoculant

Advances in Agriculture, Volume 2024, Issue 1, 2024.
Recurring use of chemical fertilizers (CFs) in agriculture has resulted the remarkable improvement in crop productivity but their ruinous effects on environment have made a serious issue. Biological entities (e.g., several microorganisms) showing fertilizer‐like activities have gained attention in this regard.

EFFECT OF Acidithiobacillus thiooxidans-CYSTEINE INTERACTIONS ON PYRITE BIOOXIDATION BY Acidithiobacillus ferrooxidans IN THE PRESENCE OF COAL COMPOUNDS [PDF]

Brazilian Journal of Chemical Engineering, 2019
Abstract This study evaluated the biooxidation of pyrite contained in a Colombian coal (2.38 mm < particle size < 0.50 mm). The variables were cysteine concentration (0-600 mg/L) and culture type (pure Acidithiobacillus ferrooxidans (ATCC 23270) and a consortium of Acidithiobacillus thiooxidans (ATCC 15494) and Acidithiobacillus ferrooxidans).

Electrogenerative leaching for sphalerite-MnO2 in the presence of Acidithiobacillus thiooxidans

Transactions of Nonferrous Metals Society of China, 2010
A dual cell system was used to study the electrogenerative leaching sphalerite-MnO2 in the presence and absence of Acidithiobacillus thiooxidans (A. thiooxidans). The polarization of anode and cathode, and the relationship between the electric quantity (Q) and some factors, such as the dissolved rate of Zn2+ and Fe2+, and the time in the bio-electro ...
