A New qPCR Assay to Detect Geosmin-Producing Cyanobacteria

, 2019
Taste-and-odor (T&O) compounds are frequently produced by cyanobacterial blooms in bodies of water. Geosmin, perhaps the most common T&O compound produced by these blooms, is not effectively removed by conventional water treatment processes and ...

Geosmin, a Food- and Water-Deteriorating Sesquiterpenoid and Ambivalent Semiochemical, Activates Evolutionary Conserved Receptor OR11A1 [Elektronisk resurs]

Geosmin, 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.

Control of MIB, geosmin and TON by membrane systems

, 2006
Control of taste and odour compounds in drinking water supplies represents a key treatment objective for many municipalities. Geosmin and 2-methylisoborneol (MIB) represent the primary compounds responsible for taste and odour present in surface waters ...

Chemical Perception and Response of the Nile Tilapia to Geosmin

, 1992
Chemical sensitivity of the Nile tilapia Tilapianilotica to geosmin was examined by the cardiac method. The fish showed cardiac deceleration in response to geosmin of various concentrations. The threshold of detection was found to be as low as 0.005 ng/l,

Phylogenomic analyses and distribution of terpene synthases among Streptomyces

Beilstein Journal of Organic Chemistry, 2019
Terpene synthases are widely distributed among microorganisms and have been mainly studied in members of the genus Streptomyces. However, little is known about the distribution and evolution of the genes for terpene synthases.

Physiology of Geosmin Production by Anabaena circinalis Isolated from the Murrumbidgee River, Australia

, 1992
Chemical analysis and sensory assessment of river waters from the Murrumbidgee and Murray Rivers showed geosmin is an important odor compound. Experiments in culture using Anabaena circinalis isolated from the Murrumbidgee River, New South Wales ...

Geosmin Biosynthesis. Streptomyces coelicolor Germacradienol/Germacrene D Synthase Converts Farnesyl Diphosphate to Geosmin

, 2016
Geosmin is responsible for the characteristic odor of moist soil. Incubation of recombinant germacradienol synthase, encoded by the SCO6073 (SC9B1.20) gene of the Gram-positive soil bacterium Streptomyces coelicolor, with farnesyl diphosphate (2, FPP) in

Feeding during off-flavour purging in recirculating aquaculture systems? An exploratory characterisation of waterborne and feedborne odour-active compounds in Russian sturgeon (Acipenser gueldenstaedtii)

Journal of Agriculture and Food Research
Off-flavours are a major challenge in recirculating aquaculture systems (RAS), with geosmin and 2-methylisoborneol (2-MIB) among key contributors to earthy taints.

The impact of ash-derived natural organic matter on the adsorption of MIB and geosmin by powdered activated carbon

Frontiers in Environmental Science
Wildfires substantially alter watershed chemistry, increasing natural organic matter (NOM) loads and nutrient fluxes into surface waters, which can stimulate algal blooms and the production of taste and odor (T&O) compounds such as 2-methylisoborneol
