Discovery and Biosynthesis of Celluxanthenes, Antibacterial Arylpolyene Alkaloids From Diverse Cellulose-Degrading Anaerobic Bacteria. [PDF]

Angew Chem Int Ed Engl
The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.

A Thermostable Bacterial Metallohydrolase that Degrades Organophosphate Plasticizers. [PDF]

Chembiochem
This bacterial enzyme, cyclase‐phosphotriesterase (C‐PTE) from Ruegeria pomeroyi DSS‐3, shows significant potential for breaking down organophosphate pollutants. Beyond its capability to hydrolyze specific plasticizers such as triphenyl phosphate and tris(2‐chloropropyl) phosphate, C‐PTE's crystal structure reveals a binuclear zinc active site, and it ...

DNA repair enzymes of the Antarctic Dry Valley metagenome

Frontiers in Microbiology, 2023
Microbiota inhabiting the Dry Valleys of Antarctica are subjected to multiple stressors that can damage deoxyribonucleic acid (DNA) such as desiccation, high ultraviolet light (UV) and multiple freeze-thaw cycles.

Temporal dynamics of geothermal microbial communities in Aotearoa-New Zealand

Frontiers in Microbiology, 2023
Microbial biogeography studies, in particular for geothermal-associated habitats, have focused on spatial patterns and/or individual sites, which have limited ability to describe the dynamics of ecosystem behaviour.

The first cultivated representatives of the actinobacterial lineage OPB41 isolated from subsurface environments constitute a novel order Anaerosomatales

Frontiers in Microbiology, 2022
The continental subsurface harbors microbial populations highly enriched in uncultured taxa. OPB41 is an uncultured order-level phylogenetic lineage within the actinobacterial class Coriobacteriia.

Genome sequencing analysis of a novel thermophilic strain Geobacillus sp. CX412

Frontiers in Microbiology, 2022
The thermophilic spore-forming strain Geobacillus sp. CX412 was isolated from hot spring soil in Tengchong City, Yunnan Province, China. We sequenced the complete genome of Geobacillus sp. CX412 using PacBio SMRT Sequencing.

Membrane proteome of the thermoalkaliphile Caldalkalibacillus thermarum TA2.A1

Frontiers in Microbiology, 2023
Proteomics has greatly advanced the understanding of the cellular biochemistry of microorganisms. The thermoalkaliphile Caldalkalibacillus thermarum TA2.A1 is an organism of interest for studies into how alkaliphiles adapt to their extreme lifestyles, as
