Microbial Signals in Cancer: Dissecting Host–Microbiota–Tumor Interactions and Potential Therapeutic Strategy

MedComm, Volume 7, Issue 9, September 2026.
Microbial signals from gut and tumor‐resident bacteria, fungi, viruses, and bacteriophages reshape immune and metabolic networks within the tumor microenvironment, thereby influencing cancer progression, treatment response. Therapeutic modulations, including dietary interventions, probiotics, antibiotics, fecal microbiota transplantation, engineered ...

Cultivation of Autotrophic Ammonia-Oxidizing Archaea from Marine Sediments in Coculture with Sulfur-Oxidizing Bacteria

, 2010
The role of ammonia-oxidizing archaea (AOA) in nitrogen cycling in marine sediments remains poorly characterized. In this study, we enriched and characterized AOA from marine sediments. Group I.1a crenarchaea closely related to those identified in marine

Relative contributions of archaea and bacteria to aerobic ammonia oxidation in the environment [PDF]

Environmental Microbiology, 2008
Summary Traditionally, organisms responsible for major biogeochemical cycling processes have been determined by physiological characterization of environmental isolates in laboratory culture. Molecular techniques have, however, confirmed the widespread occurrence of abundant bacterial and archaeal groups with no cultivated ...

Metagenomic Evidence for the Presence of Comammox Nitrospira-Like Bacteria in a Drinking Water System

mSphere, 2016
We report metagenomic evidence for the presence of a Nitrospira-like organism with the metabolic potential to perform the complete oxidation of ammonia to nitrate (i.e., it is a complete ammonia oxidizer [comammox]) in a drinking water system.

Glomus iranicum var. Tenuihypharum as a Biofertilizer Modulates Soil Microbial Community Composition and Enhances Soil Carbon Dynamics in Nectarine Cultivation

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT The development of biofertilization strategies based on arbuscular mycorrhizal fungi (AMF) represents a promising approach to enhance crop productivity and soil health while reducing the environmental footprint of conventional fertilization. This study evaluated the effects of Glomus iranicum var.

Ammonia oxidation coupled to CO2 fixation by Archaea and Bacteria in an agricultural soil

, 2011
Ammonia oxidation is an essential part of the global nitrogen cycling and was long thought to be driven only by bacteria. Recent findings expanded this pathway also to the archaea.

Enrichment and characteristics of ammonia-oxidizing archaea in wastewater treatment process

, 2022
High purity ammonia-oxidizing archaea (AOA) culture containing a single AOA strain was enriched from the filtering materials of biological aerated filter. The concentration of AOA reached 3.27 × 107 copies/mL, while its proportion was 91.40%.

Advancements and Challenges in Second‐ and Third‐Generation Biofuels: A Comparative Analysis of Lignocellulosic and Algal Feedstocks

Safety Science and Technology, Volume 1, Issue 3, September 2026.
ABSTRACT Advanced biofuels derived from nonfood biomass are increasingly recognized as strategic components of low‐carbon energy systems, particularly for sectors where direct electrification remains difficult. Second‐generation biofuels from lignocellulosic residues and third‐generation biofuels from algal and aquatic biomass offer complementary ...

Effects of Perovskia abrotanoides Kar. Essential Oil on Greenhouse Gas Mitigation and Energy Efficiency Improvement in Sheep Rumen: An In Vitro Study

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
The essential oil of Perovskia abrotanoides Kar. (rich in 1,8‐cineole and camphor) linearly reduced methane production (up to 57.5%) and total protozoa population in sheep rumen fluid in vitro. Simultaneously, it increased microbial biomass production, microbial synthesis efficiency and the partitioning factor, indicating improved rumen energy ...

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

Ecological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.
