Bioleaching as an Eco‐Friendly Nano‐Factory for Sustainable Inorganic Waste Management: Current Advancements, Challenges, and Opportunities

ChemistryOpen, Volume 14, Issue 9, September 2025.
The review explores the latest updates and information about the global trends and hazards of e‐waste and also discusses the bioleaching of metals and nanoparticles from various inorganic wastes. It also focuses on the mechanistic pathway of the bioleaching process and computational aspects. Inorganic waste management and metal recovery technology pose

Proteomics Analysis of Thermoplasma acidophilum with a Focus on Protein Complexes [PDF]

Molecular & Cellular Proteomics, 2007
Two-dimensional gel electrophoresis (2DE) and MALDI-TOF MS were used to obtain a global view of the cytoplasmic proteins expressed by Thermoplasma acidophilum. In addition, glycerol gradient ultracentrifugation coupled to 2DE-MALDI-TOF MS analysis was used to identify subunits of macromolecular complexes.

Quinone Profiles of Thermoplasma acidophilum HO-62 [PDF]

Journal of Bacteriology, 2001
ABSTRACT Quinones of Thermoplasma acidophilum HO-62 were analyzed by high-performance liquid chromatography, mass spectrometry, and nuclear magnetic resonance. Menaquinone, methionaquinone, and 2- trans and 2- cis forms of thermoplasmaquinone were identified.

Exploring the human archaeome: its relevance for health and disease, and its complex interplay with the human immune system

The FEBS Journal, Volume 292, Issue 6, Page 1316-1329, March 2025.
This work investigates the archaeome, an essential segment of the human microbiome, focusing on its relationship with the immune system. Here, we outline the types of archaea across different body areas and underscore possible links to health issues, such as obesity and specific cancers.

The origins of phagocytosis and eukaryogenesis

Biology Direct, 2009
Background Phagocytosis, that is, engulfment of large particles by eukaryotic cells, is found in diverse organisms and is often thought to be central to the very origin of the eukaryotic cell, in particular, for the acquisition of bacterial endosymbionts

Identification, characterization and classification of prokaryotic nucleoid‐associated proteins

Molecular Microbiology, Volume 123, Issue 3, Page 206-217, March 2025.
Nucleoid‐associated proteins (NAPs) structure DNA by either bending, wrapping, bridging, or forming protein filaments on the DNA. We review newly identified NAPs and provide a list of simple biochemical assays to study the DNA‐structuring properties of novel NAPs. Abstract Common throughout life is the need to compact and organize the genome.

Geomicrobiology of a seawater-influenced active sulfuric acid cave.

PLoS ONE, 2019
Fetida Cave is an active sulfuric acid cave influenced by seawater, showing abundant microbial communities that organize themselves under three main different morphologies: water filaments, vermiculations and moonmilk deposits.

Architectures of archaeal GINS complexes, essential DNA replication initiation factors

BMC Biology, 2011
Background In the early stage of eukaryotic DNA replication, the template DNA is unwound by the MCM helicase, which is activated by forming a complex with the Cdc45 and GINS proteins.

Chromatin and gene regulation in archaea

Molecular Microbiology, Volume 123, Issue 3, Page 218-231, March 2025.
Recent data from diverse archaea with different repertoires of nucleoid‐associated proteins show a common genome‐wide chromatin organisation where chromatin maintains access to gene promoters independently of transcription activity. Abstract The chromatinisation of DNA by nucleoid‐associated proteins (NAPs) in archaea ‘formats’ the genome structure in ...

Purification and properties of pyruvate kinase fromThermoplasma acidophilum [PDF]

FEMS Microbiology Letters, 1992
Thermoplasma acidophilum is a thermoacidophilic archaebacterium occupying a paradoxical place in phylogenetic trees (phenotypically it is a thermoacidophile but phylogenetically it classifies with the methanogens). To better understand its phylogeny, the pyruvate kinase from this organism is being investigated as a molecular marker. The enzyme has been
