Geosmin Biosynthesis. Mechanism of the Fragmentation−Rearrangement in the Conversion of Germacradienol to Geosmin

, 2016
Geosmin (1) is responsible for the characteristic odor of moist soil. Incubation of farnesyl diphosphate (2, FPP) with recombinant Streptomyces coelicolor germacradienol/geosmin synthase generated geosmin (1), germacradienol (3), germacrene D (4 ...

Ability of Bacillus to Degrade Geosmin

, 1983
The ability of Bacillus strains to degrade geosmin, a musty off-flavor component present in superficial waters, led some authors to postulate the existence of a Bacillus exoenzyme: the “geosminase”.

Seasonal Fluctuations in Geosmin and Terpenes in Rainbow Trout (Oncorhynchus mykiss) in an Outdoor Commercial Recirculated Aquaculture System Facility

Fishes
Seasonal changes in geosmin and selected terpenes in rainbow trout (Oncorhynchus mykiss) in an outdoor recirculated aquaculture system (RAS) in Denmark were followed over three months.

A Hierarchy of Crossmodal Odor Associations: Exploring the Role of Pleasantness and Edibility in Odor Crossmodal Associations Across the Senses

Topics in Cognitive Science, EarlyView.
Abstract Crossmodal associations with odors have the potential to aid in odor perception and language. In addition, identifying the dimensions that drive odor crossmodal associations may help understand the critical dimensions underlying odor perception more generally.

Acute toxicity of fine and coarse copper sulfate crystals to planorbid snails in experimental catfish ponds

Journal of the World Aquaculture Society, Volume 57, Issue 6, December 2026.
Abstract Bolbophorus damnificus, a digenetic trematode infecting ictalurid catfish, causes substantial economic losses in commercial aquaculture through a parasite‐induced anemia, leading to poor performance and increased susceptibility to secondary bacterial infections.

Effects of nutritional factors on the geosmin production of Lyngbya kuetzingii UTEX 1547 (Oscillatoriales, Cyanobacteria)

, 2017
The effects of phosphate-P (PO4-P), nitrate-N (NO3-N), and calcium ion (Ca2+) on the geosmin production of Lyngbya kuetzingii UTEX 1547, a geosmin-producing cyanobacterium, were investigated. All nutrients had significant effects on geosmin production (P

Utilizing a consumer taste panel to assess the geosmin sensory detection threshold in market‐size Atlantic salmon, Salmo salar, produced in land‐based aquaculture systems

Journal of the World Aquaculture Society
Microbially derived geosmin causes an earthy off‐flavor in Atlantic salmon, Salmo salar, produced in land‐based systems, placing these products at risk for rejection. Therefore, a study was conducted to investigate the geosmin sensory threshold in market‐

Geosmin off-flavour in pond-raised fish in southern Bangladesh and occurrence of potential off-flavour producing organisms

Aquaculture Environment Interactions, 2014
Pangas Pangasianodon hypophthalmus and tilapia Oreochromis niloticus were cultivated for 6 mo in earthen ponds in Bangladesh to examine occurrence of the off-flavour geosmin in water and fish and to test procedures for reduction of off-flavour.

Mining of Cyanobacterial Genomes Indicates Natural Product Biosynthetic Gene Clusters Located in Conjugative Plasmids

Frontiers in Microbiology, 2021
Microbial natural products are compounds with unique chemical structures and diverse biological activities. Cyanobacteria commonly possess a wide range of biosynthetic gene clusters (BGCs) to produce natural products.

Evolutionäre, funktionelle und mechanistische Charakterisierung mikrobieller Terpensynthase‐ähnlicher Gene aus Springschwänzen

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Eine Genomanalyse zeigte das Vorkommen zahlreicher Terpensynthasen des bakteriellen Typs in Springschwänzen. Vier Enzyme aus Sinella curviseta wurden funktionell charakterisiert, was zur Isolierung mehrerer Verbindungen führte, darunter Sinellenether, der erste identifizierte Diterpenether einer Terpensynthase mit einem neuartigen Grundgerüst.
