Geosmin Events Associated with Dolichospermum circinale Abundance Promoted by Nitrogen Supply in a Chinese Large Tropical Eutrophic Reservoir [PDF]
MicroorganismsTaste and odor (T/O) compounds are a global threat in drinking water, mainly produced by cyanobacteria in freshwater environments. Temperature plays a crucial role in regulating geosmin dynamics in temperate and subtropical lakes, while its influence may

Determination of Geosmin and 2-Methylisoborneol and Associated Microbial Composition in Rainbow Trout Aquaculture Systems for Human Consumption [PDF]
FoodsThis study investigated the seasonal and spatial dynamics of off-flavour compounds—geosmin and 2-methylisoborneol (2-MIB)—in an intensive rainbow trout (Oncorhynchus mykiss) aquaculture system for human consumption in western Spain. Weekly water and fish

qPCR-Based Monitoring of 2-Methylisoborneol/Geosmin-Producing Cyanobacteria in Drinking Water Reservoirs in South Korea [PDF]
Microorganisms, 2023 Cyanobacteria can exist in water resources and produce odorants. 2-Methylisoborneol (2-MIB) and geosmin are the main odorant compounds affecting the drinking water quality in reservoirs.

A Detailed View on Geosmin Biosynthesis
ChemBioChem, 2023 The bacterial geosmin synthase is a fascinating bifunctional enzyme that has been discovered almost two decades ago. Several aspects of the cyclisation mechanism from FPP to geosmin are known, but a detailed picture of the stereochemical course of this ...

Insights into the Seasonal Olfactory Mechanism of Geosmin in Raw Water of Huangpu River
Toxics, 2022 Since the 1990s, the raw water of Huangpu River in Shanghai, China, has intermittently encountered off-flavor contamination. In this work, the concentrations of typical odor, geosmin, in raw water of Huangpu River are found to shift along with the ...

Geosmin, a Food- and Water-Deteriorating Sesquiterpenoid and Ambivalent Semiochemical, Activates Evolutionary Conserved Receptor OR11A1. [PDF]
J Agric Food ChemGeosmin, a ubiquitous volatile sesquiterpenoid of microbiological origin, is causative for deteriorating the quality of many foods, beverages, and drinking water, by eliciting an undesirable “earthy/musty” off-flavor.

Biocontrol of Geosmin Production by Inoculation of Native Microbiota during the Daqu-Making Process
Fermentation, 2022 Geosmin produced by Streptomyces can cause an earthy off-flavor at trace levels, seriously deteriorating the quality of Chinese liquor. Geosmin was detected during the Daqu (Chinese liquor fermentation starter)-making process, which is a multi-species ...

Streptophage-mediated control of off-flavour taint producing streptomycetes isolated from barramundi ponds [PDF]
Synthetic and Systems Biotechnology, 2017 Off-flavour taint of aquaculture products is a global issue reducing consumer confidence in the farmed produce as they are taken up via the gills of fish, and deposited in the lipids of the animal.
