Species-Specific Recognition of Sulfolobales Mediated by UV-Inducible Pili and S-Layer Glycosylation Patterns

mBio, 2020
The UV-inducible pili system of Sulfolobales (Ups) mediates the formation of species-specific cellular aggregates. Within these aggregates, cells exchange DNA to repair DNA double-strand breaks via homologous recombination. Substitution of the Sulfolobus

Sessile Lifestyle Offers Protection against Copper Stress in Saccharolobus solfataricus

Microorganisms, 2023
Some archaea from the genus Sulfolobus are important for bioleaching of copper, where metal resistant microorganisms are required. Biofilm generation is one of the ways microorganisms cope with some stimuli in nature, including heavy metals. The response

Energy use efficiency of soil microorganisms: Driven by carbon recycling and reduction

Global Change Biology, Volume 29, Issue 22, Page 6170-6187, November 2023., 2023
We linked carbon use efficiency (CUE) and energy use efficiency (EUE) considering the nominal oxidation state of carbon (NOSC) of microbial biomass and element compositions of substrates utilized by microorganisms. The mean microbial EUE (0.32–0.35) is 18% lower than CUE (0.41) using glucose as a substrate, indicating that microbial growth is limited ...

Isolation of archaeal viruses with lipid membrane from Tengchong acidic hot springs

Frontiers in Microbiology, 2023
Archaeal viruses are one of the most mysterious parts of the virosphere because of their diverse morphologies and unique genome contents. The crenarchaeal viruses are commonly found in high temperature and acidic hot springs, and the number of identified

DNA Polymerase B1 Binding Protein 1 Is Important for DNA Repair by Holoenzyme PolB1 in the Extremely Thermophilic Crenarchaeon Sulfolobus acidocaldarius

Microorganisms, 2021
DNA polymerase B1 (PolB1) is a member of the B-family DNA polymerase family and is a replicative DNA polymerase in Crenarchaea. PolB1 is responsible for the DNA replication of both the leading and lagging strands in the thermophilic crenarchaeon ...
