Heteroduplex formation, mismatch resolution, and genetic sectoring during homologous recombination in the hyperthermophilic archaeon Sulfolobus acidocaldarius

Frontiers in Microbiology, 2012
Hyperthermophilic archaea exhibit certain molecular-genetic features not seen in bacteria or eukaryotes, and their systems of homologous recombination (HR) remain largely unexplored in vivo.

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes

Advanced NanoBiomed Research, Volume 6, Issue 6, June 2026.
Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

Asymmetric Reduction of Unactivated Alkenes

Chemistry – A European Journal, Volume 32, Issue 18, 14 May 2026.
Unactivated alkenes rank among the most inert functional groups in synthesis and their selective reduction remains challenging. This Review charts the evolution from classical metal‐catalyzed hydrogenation to radical hydrogen atom transfer (HAT) and emerging biocatalytic concepts, highlighting how complementary mechanistic strategies, including the ...

Microbial regulation of global macroalgal blooms (green tides): From holobiont interactions to bloom dynamics and biogeochemistry

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...

Genome sequencing of Sulfolobus sp. A20 from Costa Rica and comparative analyses of the putative pathways of carbon, nitrogen and sulfur metabolism in various Sulfolobus strains

Frontiers in Microbiology, 2016
The genome of Sulfolobus sp. A20 isolated from a hot spring in Costa Rica was sequenced. This circular genome of the strain is 2,688,317 bp in size and 34.8% in G+C content, and contains 2,591 open reading frames (ORFs). Strain A20 shares ~95.6% identity

Evolution of lysine and arginine biosynthesis revealed by substrate specificity of lysine biosynthetic enzymes in Thermus thermophilus

The FEBS Journal, Volume 293, Issue 6, Page 1727-1740, March 2026.
Two enzymes from the Thermus thermophilus lysine biosynthetic pathway, LysZ and LysY, unexpectedly exhibit substrate promiscuity. They are able to recognize the LysW intermediates utilized by the ArgW‐mediated arginine route, even though the bacterium already possesses the canonical arginine biosynthetic pathway.

Survival and Biofilm Formation of Pseudomonas Putida Under Glucose Starvation on Model Sand Surfaces

European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.
P. putida retains viability in sand columns for an extended period of at least 80 days under carbon‐deprivation P. putida increased protein production on their surfaces, enhancing biofilm integrity and adhesion to sand surfaces compared to fed biofilms.
