Glucose‐Maltodextrin as Synergistic Carbon Sources Enhance Biofloc Technology: Stabilizing Water Quality, Enriching Microbial Diversity, and Boosting Production in Cherax quadricarinatus Aquaculture

Aquaculture Research, Volume 2026, Issue 1, 2026.
Global aquaculture expansion necessitates sustainable technologies like biofloc technology (BFT), and the type of carbon source exerts a crucial impact on the functionality of biofloc systems. This study aimed to evaluate the effects of single carbon sources (glucose [G] and maltodextrin [M]) and their 1:1 mixture (GM) on water quality, microbial ...

Assessing the Genotoxic Effects of Emerging Organic Contaminants in Water Systems: Current Trends and Future Directions

Scientifica, Volume 2026, Issue 1, 2026.
Emerging organic contaminants (EOCs) represent a growing concern for global water security due to their persistence, bioactivity, and potential to induce genotoxic effects in aquatic organisms and humans. This review critically examines the current state of genotoxicity assessment for EOCs by integrating established testing frameworks with advanced ...

Meta-analysis reveals ammonia-oxidizing bacteria respond more strongly to nitrogen addition than ammonia-oxidizing archaea [PDF]

, 2016
Shifts in microbial communities driven by anthropogenic nitrogen (N) addition have broad-scale ecological consequences. However, responses of microbial groups to exogenous N supply vary considerably across studies, hindering efforts to predict community ...

Microbial and Metabolomic Variations Correlated With Gastric Cancer Subtypes and Prognosis

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Multi‐omics analysis of 50 GC patients revealed conserved microbial‐metabolite signatures across Lauren/ZJU subtypes, with ZJU‐specific features—Eubacterium_ventriosum_group and N6‐Succinyl Adenosine—enabling superior prognostic stratification. ABSTRACT Gastric cancer (GC) persists as the third most prevalent malignancy in China.

Spatial interaction of archaeal ammonia-oxidizers and nitrite-oxidizing bacteria in an unfertilized grassland soil

Frontiers in Microbiology, 2016
Interrelated successive transformation steps of nitrification are performed by distinct microbial groups – the ammonia-oxidizers, comprising ammonia-oxidizing archaea (AOA) and bacteria (AOB), and nitrite-oxidizers such as Nitrobacter and Nitrospira ...

Activity and Metabolic Versatility of Complete Ammonia Oxidizers in Full-Scale Wastewater Treatment Systems

mBio, 2020
The recent discovery of complete ammonia oxidizers (comammox) contradicts the paradigm that chemolithoautotrophic nitrification is always catalyzed by two different microorganisms.
