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

Myxobacteria isolated from recirculating aquaculture systems (RAS): ecology and significance as off-flavor producers [PDF]
Applied and Environmental MicrobiologyDespite advances in the operation of recirculating aquaculture systems (RAS), accumulation of earthy-muddy off-flavors in the fish remains a potential risk.

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.

Type-specific molecular signaling architectures and synaptic plasticity of Drosophila olfactory sensory neurons [PDF]
Frontiers in Cellular NeuroscienceOlfactory sensory neurons (OSNs) detect odours at a wide range of intensities. In Drosophila, volatile compounds bind to specific odorant receptors (ORs), which tune the sensitivity of chemoreception.

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 suppresses defensive behaviour and elicits unusual neural responses in honey bees
Scientific Reports, 2023 Geosmin is an odorant produced by bacteria in moist soil. It has been found to be extraordinarily relevant to some insects, but the reasons for this are not yet fully understood. Here we report the first tests of the effect of geosmin on honey bees.

G3: Genes, Genomes, Genetics, 2021 Geosmin, a degraded sesquiterpene molecule with earthy and musty odor, imbues table beet with its characteristic aroma. Geosmin is heritable and endogenously produced in table beet; its earthy aroma is sought by some consumers but deters others.
