Living review framework for better policy design and management of hazardous waste in Australia.

The significant increase in hazardous waste generation in Australia has led to the discussion over the incorporation of artificial intelligence into the hazardous waste management system. Recent studies explored the potential applications of artificial intelligence in various processes of managing waste. However, no study has examined the use of text mining in the hazardous waste management sector for the purpose of informing policymakers.

Genome-based classification of two halotolerant extreme acidophiles, Acidihalobacter prosperus V6 (=DSM 14174 =JCM 32253) and 'Acidihalobacter ferrooxidans' V8 (=DSM 14175 =JCM 32254) as two new species, Acidihalobacter aeolianus sp. nov. and Acidihalobacter ferrooxydans sp. nov., respectively.

Phylogenomic analysis of recently released high-quality draft genome sequences of the halotolerant acidophiles, Acidihalobacter prosperus V6 (=DSM 14174=JCM 32253) and 'Acidihalobacter ferrooxidans' V8 (=DSM 14175=JCM 32254), was undertaken in order to clarify their taxonomic relationship. Sequence based phylogenomic approaches included 16S rRNA gene phylogeny, multi-gene phylogeny from the concatenated alignment of nine selected housekeeping genes and multiprotein phylogeny using clusters of orthologous groups of proteins from ribosomal protein families as well as those from complete sets of markers based on concatenated alignments of universal protein families. Non-sequence based approaches for species circumscription were based on analyses of average nucleotide identity, which was further reinforced by the correlation indices of tetra-nucleotide signatures as well as genome-to-genome distance (digital DNA-DNA hybridization) calculations.

Quantitative proteomics using SWATH-MS identifies mechanisms of chloride tolerance in the halophilic acidophile Acidihalobacter prosperus DSM 14174.

In this study, the differential protein expression of the acidophilic halophile, Acidihalobacter prosperus DSM 14174 (strain V6) was studied with the aim of understanding its mechanisms of tolerance to high chloride ion stress in the presence of low pH, using Sequential Window Acquisition of all Theoretical Mass Spectra (SWATH-MS). In acidophiles, chloride stress results in both osmotic stress as well as acidification of the cytoplasm due to the ability of chloride to permeate the cell membrane and disrupt the reversed transmembrane potential which normally extrudes protons. The proteomic response of A.

In a quest for engineering acidophiles for biomining applications: challenges and opportunities.

Biomining with acidophilic microorganisms has been used at commercial scale for the extraction of metals from various sulfide ores. With metal demand and energy prices on the rise and the concurrent decline in quality and availability of mineral resources, there is an increasing interest in applying biomining technology, in particular for leaching metals from low grade minerals and wastes. However, bioprocessing is often hampered by the presence of inhibitory compounds that originate from complex ores.

Draft Genome Sequence of DSM 14175 (Strain V8), a New Iron- and Sulfur-Oxidizing, Halotolerant, Acidophilic Species.

The use of halotolerant acidophiles for bioleaching provides a biotechnical approach for the extraction of metals from regions where high salinity exists in the ores and source water. Here, we describe the first draft genome of a new species of a halotolerant and iron- and sulfur-oxidizing acidophile, DSM 14175 (strain V8).

Draft Genome Sequence of the Acidophilic, Halotolerant, and Iron/Sulfur-Oxidizing Acidihalobacter prosperus DSM 14174 (Strain V6).

The principal genomic features of Acidihalobacter prosperus DSM 14174 (strain V6) are presented here. This is a mesophilic, halotolerant, and iron/sulfur-oxidizing acidophile that was isolated from seawater at Vulcano, Italy. It has potential for use in biomining applications in regions where high salinity exists in the source water and ores.
