Ammonia Oxidation by the Arctic Terrestrial Thaumarchaeote Candidatus Nitrosocosmicus arcticus Is Stimulated by Increasing Temperatures

Frontiers in Microbiology, 2019
Climate change is causing arctic regions to warm disproportionally faster than those at lower latitudes, leading to alterations in carbon and nitrogen cycling, and potentially higher greenhouse gas emissions.

Candidatus Nitrosocaldus cavascurensis, an Ammonia Oxidizing, Extremely Thermophilic Archaeon with a Highly Mobile Genome

Frontiers in Microbiology, 2018
Ammonia oxidizing archaea (AOA) of the phylum Thaumarchaeota are widespread in moderate environments but their occurrence and activity has also been demonstrated in hot springs. Here we present the first enrichment of a thermophilic representative with a

Noncoding RNAs in Host–Microbiota Interaction

Animal Research and One Health, EarlyView.
The intricate interplay between gut microbiota and the host exerts a profound impact on host biological processes and disease development. This review highlights the pivotal role of noncoding RNAs (ncRNAs) in this interaction. Host ncRNAs regulate gene expression and microbiota composition, whereas microbial small RNAs (sRNAs) modulate host gene ...

Antibiotic Sensitivity of Vibrio spp. and Shewanella algae Isolated From Brood and Egg of Mud Crab Hatchery

Animal Research and One Health, EarlyView.
Vibrio alginolyticus NBRC 15630, Vibrio parahaemolyticus ATCC 17802, Shewanella algae DW01, and Shewanella algae ATCC 51192 bacterial strains were found in the Mud crab brood and egg samples. All isolates were found to be sensitive to cefotaxime, chloramphenicol, gentamicin, and nitrofurantoin antibiotics.

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

The cardiolipin analogues of Archaea

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2009
The present article reviews studies of the structure and functional roles of the cardiolipin analogues of extremely halophilic prokaryotes belonging to the Archaea domain. Analogies and differences between the archaeal bisphosphatidylglycerol and the mitochondrial cardiolipin are presented. Furthermore the structure of archaeal glycophospholipid dimers

Biochar in the circular bioeconomy: a bibliometric analysis of technologies, applications, and trends

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biochar has attracted considerable attention in recent years for its wide‐ranging applications, particularly its role in carbon sequestration as a strategy to mitigate greenhouse gas emissions. Its emerging uses within the circular bioeconomy also position it as a valuable tool for environmental management, and ongoing research continues to ...

Identification of novel components of the Ced and Ups systems in Saccharolobus islandicus REY15A

mLife
In Sulfolobales cells, transcription of the Ups (UV‐inducible pili of Sulfolobus) and Ced (Crenarchaeal system for exchange of DNA) genes is highly induced by DNA damage, and the two systems play key roles in pili‐mediated cell aggregation and ...

Integrating enzyme production and bioenergy recovery through circular bioprocessing of carbohydrate‐rich food wastes into α‐amylase, hydrogen and methane

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study explored the valorization of two carbohydrate rich food wastes, a sugary (spoiled dates, SD) and a starchy (wasted rice, WR) one, for the biotechnological production of α‐amylase, biohydrogen (bioH2), and methane (CH4). Initially, the bioH2 and CH4 production potentials of raw SD and WR were assessed without any pretreatment, via ...

Contrasting bacterial and archaeal distributions reflecting different geochemical processes in a sediment core from the Pearl River Estuary

AMB Express, 2020
Microbial community structure and metabolic activities have profound impacts on biogeochemical processes in marine sediments. Functional bacteria such as nitrate- and sulfate-reducing bacteria respond to redox gradients by coupling specific reactions ...
