Biotehnološki značajna bakterija Nitrospira u geotermalnim izvorima Republike Hrvatske [PDF]

, 2020
Mikrobne zajednice geotermalnih izvora izvrstan su primjer mogućnosti odvijanja života u ekstremnim uvjetima. Poznavanje ekstremofilnih zajednica poput termofilnih bakterija ključno je za daljnje razumijevanje metabolizma, strukture i međusobnih odnosa unutar ekosustava.

Cultivation and Transcriptional Analysis of a Canonical Nitrospira Under Stable Growth Conditions

Frontiers in Microbiology, 2019
Nitrite-oxidizing bacteria (NOB) are vital players in the global nitrogen cycle that convert nitrite to nitrate during the second step of nitrification.

Disturbance-based management of ecosystem services and disservices in partial nitritation-anammox biofilms

npj Biofilms and Microbiomes, 2022
The resistance and resilience provided by functional redundancy, a common feature of microbial communities, is not always advantageous. An example is nitrite oxidation in partial nitritation-anammox (PNA) reactors designed for nitrogen removal in ...

Stability and performance of two GSBR operated in alternating anoxic/aerobic or anaerobic/aerobic conditions for nutrient removal [PDF]

, 2012
Two granular sludge sequencing batch reactors (GSBR) with alternating anoxic/aerobic (R1) and anaerobic/aerobic (R2) conditions were operated with a 4-carbon-source synthetic influent. The physical properties of the granular sludge were very good (SVI≈20

Biological Conversion of Formate to Organic Compounds: Toward a Sustainable Formate Bioeconomy

Carbon Energy, Volume 8, Issue 1, January 2026.
Formate bioconversion plays a crucial role in achieving renewable resource utilization and sustainable development. To tap its full potential, it is important to identify the most appropriate microbial hosts for incorporating formate into building blocks, design the most promising metabolic pathways for transmitting formate into central carbon ...

Topological data analysis of Escherichia coli O157:H7 and non-O157 survival in soils. [PDF]

, 2014
Shiga toxin-producing E. coli O157:H7 and non-O157 have been implicated in many foodborne illnesses caused by the consumption of contaminated fresh produce.

Vermicompost Alters Soil Microbial Communities and Decomposition but Increases Nitrate Leaching in Tropical Sugarcane

Ecology and Evolution, Volume 16, Issue 1, January 2026.
A six‐week field trial in Australian sugarcane soil used metabarcoding, trait‐based analysis and structural equation modelling to test how vermicompost affects soil biodiversity, decomposition and nitrate leaching under tropical conditions. Vermicompost shifted bacterial community composition and accelerated decomposition, yet increased nitrate ...

Microbial nitrogen removal and recycling in the redox transition zone of a meromictic lake and its coupling to sulfur cycling

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Organotrophic denitrification is an important nitrogen (N) removal process in lakes, but alternative N reduction processes such as lithotrophic sulfur (S)‐oxidizing denitrification may be greatly underappreciated. We studied the redox transition zone (RTZ) in the meromictic water column of the North Basin of Lake Lugano (Switzerland) to ...

Achieving short-cut nitrification and denitrification in modified intermittently aerated constructed wetland [PDF]

, 2017
This study aim to enhance nitrogen removal performance via shifting nitrogen removal pathway from nitrate to nitrite pathway. It was demonstrated that nitrite pathway was successfully and stably achieved in CWs by using modified intermittent aeration ...

Dynamics and Eco‐Genomics of Baltic Sea Nitrifiers: Seasonality, Niches, Interactions and Genomic Uniqueness

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Nitrifiers in the Baltic Sea show persistent abundance in aphotic waters and late‐fall to winter photic zone increases positively correlated with nutrients and negatively with light and chlorophyll. Through selective enrichment, five novel ammonia‐oxidising archaea genomes were recovered, including the dominant aphotic taxon, which revealed overall ...
