A Review on Potentially Probiotic Yeasts From Traditional Fermented Products in Sub‐Saharan Africa for Sustainable Food Systems and Improved Health

Food Safety and Health, Volume 4, Issue 1, Page 4-30, January 2026.
This review focuses on the potential of sub‐Saharan African fermented food products as sources of probiotic yeasts for improved food security and health. ABSTRACT Research on probiotic yeasts from fermented products in sub‐Saharan Africa was limited in the past, but there is currently a surge in investigative efforts in this field.

Analysis and Quantification of Ammonia-Oxidizing Bacteria Community with amoA Gene in Sewage Treatment Plants

Journal of Microbiology and Biotechnology, 2012
The analysis and quantification of ammonia-oxidizing bacteria (AOB) is crucial, as they initiate the biological removal of ammonia-nitrogen from sewage. Previous methods for analyzing the microbial community structure, which involve the plating of samples or culture media over agar plates, have been inadequate because many microorganisms found in a ...

Comparative in silico analysis of PCR primers suited for diagnostics and cloning of ammonia monooxygenase genes from ammonia-oxidizing bacteria [PDF]

, 2008
Over recent years, several PCR primers have been described to amplify genes encoding the structural subunits of ammonia monooxygenase (AMO) from ammonia-oxidizing bacteria (AOB).

Land Cover and Hydrology Regulate Riverine Carbon Emissions From Subarctic Catchments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Streams transport carbon (C) and nutrients across the terrestrial‐aquatic interface and are significant sources of methane (CH4) and carbon dioxide (CO2) to the atmosphere. Climate‐induced changes in vegetation and hydrology increase the export of dissolved organic carbon (DOC) from terrestrial to aquatic ecosystems, but the impact of these ...

Variation in soil nitrous oxide emission with nitrogen application rates under reclaimed water irrigation

Frontiers in Environmental Science
Nitrous oxide (N2O) is a potent greenhouse gas primarily emitted from agricultural soils through microbial nitrogen transformation processes. Different nitrogen application rates and fertilizer types influence soil nitrogen transformation pathways ...

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 ...

Community analysis of betaproteobacterial ammonia-oxidizing bacteria using the amoCAB operon [PDF]

, 2009
The genes and intergenic regions of the amoCAB operon were analyzed to establish their potential as molecular markers for analyzing ammonia-oxidizing betaproteobacterial (beta-AOB) communities.

Optimizing Environmental Conditions and Media for the Vegetative Growth of Two Indigenous Pleurotus sajor-caju Strains

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Pleurotus sajor-caju strains (PscW and PscA), indigenous to Wli forest in the Volta region and Atewa forest in the Eastern region of Ghana, respectively, were studied to identify optimal cultivation conditions. This research aimed to determine the ideal temperature, pH and growth media for the vegetative development of these oyster mushrooms strains ...

Environmental factors shaping the ecological niches of ammonia-oxidizing archaea [PDF]

, 2009
For more than 100 years it was believed that bacteria were the only group responsible for the oxidation of ammonia. However, recently, a new strain of archaea bearing a putative ammonia monooxygenase subunit A (amoA) gene and able to oxidize ammonia was ...
