Current understanding of electroautotrophy and its relevance in astrobiology‐related research

mLife, Volume 4, Issue 5, Page 473-493, October 2025.
Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Microbial transformation of elements: the case of arsenic and selenium [PDF]

, 2010
Microbial activity is responsible for the transformation of at least one third of the elements in the periodic table. These transformations are the result of assimilatory, dissimilatory, or detoxification processes and form the cornerstones of many ...

Biotimer assay: A reliable and rapid method for the evaluation of central venous catheter microbial colonization [PDF]

, 2017
Adherent bacteria and biofilm frequently colonize central venous catheters (CVCs). CVC colonization is correlated to infections and particularly to bloodstream ones.

Heterotrophic ammonia oxidation by Alcaligenes balances ROS generation and terminal electron transport

mLife, Volume 4, Issue 5, Page 527-538, October 2025.
Abstract Heterotrophic nitrifiers are bacteria that aerobically oxidize ammonia in the presence of organic carbon sources, which differs from autotrophic nitrifiers that extract energy from ammonia oxidation for cell metabolism and growth. The physiological significance of heterotrophic ammonia oxidation remains unclear, even though this process has ...

Characterization of the microbial communities in Tunisian wild populations of the Mediterranean fruit fly (Ceratitis capitata) and their implications for the future implementation of the sterile insect technique

Insect Science, Volume 32, Issue 5, Page 1650-1668, October 2025.
A comprehensive comparative analysis of microbial community profiles has been conducted between distinct Medfly populations situated in different regions of Tunisia, revealing patterns in their bacteriome composition. In the Tozeur population, a substantially elevated relative abundance of the bacterial genus Serratia has been identified, which ...

Improvement of colony management in insect mass‐rearing for sterile insect technique applications

Insect Science, Volume 32, Issue 5, Page 1476-1494, October 2025.
Abstract Sterile Insect Technique (SIT) applications against major insect pests and disease vectors rely on the cost‐effective production of high‐quality sterile males. This largely depends on the optimal management of target pest colonies by maximizing the benefits provided by a genetically rich and pathogen‐free mother colony, the presence of ...

Three Dimensional Structural Modelling of Lipase Encoding Gene from Soil Bacterium Alcaligenes sp. JG3 Using Automated Protein Homology Analysis

Indonesian Journal of Chemistry, 2019
Bacterial lipases have significant potential to be used as the biocatalyst for many chemical reactions. In this study, a novel gene encoding lipase was isolated from an Alcaligenes sp. JG3. A pair of designed primer has successfully isolated 1 kb (LipJG3)

Phenol Biodegradation by Two Xenobiotics-Tolerant Bacteria Immobilized in Polyethylene Oxide Cryogels [PDF]

, 2009
Biofilms were formed on poly(ethylene oxide) (PEO) cryogels by using bacteria cultured from xenobiotics polluted environments and their phenol biodegrading capability was studied.

Tracking Protein Motions using Serial Femtosecond Crystallography with X‐Ray Free‐Electron Laser

Current Protocols, Volume 5, Issue 9, September 2025.
Abstract Since the birth of biochemistry, researchers have investigated the structure–function relationship of a wide variety of proteins. However, until recently, when X‐ray free‐electron lasers (XFELs) became available, it was not possible to visualize the motion of proteins from moment to moment with excellent temporal and spatial resolution.
