Accumulation and Release of Geosmin during the Growth Phases of Anabaena circinalis (Kutz.) Rabenhorst

, 1992
Anabaena circinalis (Kutz.) Rabenhorst was isolated during a taste and odor episode characterized by high concentrations of geosmin, with raw water containing up to 45 ng geosmin/L.

Development of a novel quantitative PCR assay as a measurement for the presence of geosmin-producing fungi [PDF]

, 2015
Geosmin‐associated gpe1 gene of Penicillium expansum displayed ≥99% similarity to cytochrome P450 gene of geosmin‐producing P. restrictum, but ≤40% similarities to geosmin biosynthesis, non‐cytochromic gene of Streptomyces avermitilis and cytochrome P450

Removal of Algae, and Taste and Odor Compounds by a Combination of Plant-Mineral Composite (PMC) Coagulant with UV-AOPs: Laboratory and Pilot Scale Studies

Applied Sciences, 2018
The seasonal occurrence of algae blooms in surface waters remains a common problem, such as taste and odor (T&Os), the risk of disinfection by-products (DBPs), and disturbance to water treatment systems.

HS-SPME-GC/MS Method for the Simultaneous Determination of Trihalomethanes, Geosmin, and 2-Methylisoborneol in Water Samples

Chemosensors, 2023
Drinking water treatment plants (DWTP) use chlorination as an oxidation stage in the first step of the processes used to eliminate the natural organic matter (NOM) responsible for the formation of 2-methylisoborneol (2-MIB) and Geosmin (GM), which ...

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, Volume 82, Issue 9, Page 8132-8151, September 2026.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Influence of Returned Water from Sludge Treatment and Return Activated Sludge on 2-Methylisoborneol and Geosmin Behaviors and Concentrations during Wastewater Treatment

Journal of Water and Environment Technology
Compounds such as 2-methylisoborneol (2-MIB) and geosmin present in the final effluents of wastewater treatment plants may affect water treatment in downstream areas. To reduce the concentrations of 2-MIB and geosmin, we investigated the influence of the

Case Study on the Application of a Commercial Microbial Consortium to Reduce Off-Flavour in a Recirculating Aquaculture System for Nile tilapia (Oreochromis niloticus) Production

Aquaculture Journal
The impact of a commercial microbial population (product name “RAS Right”) on the off-flavours geosmin and 2-methylisoborneol (2-MIB) in water and fish of a recirculating aquaculture system (RAS) for Nile tilapia production was studied over five months ...

Streptophage-mediated control of off-flavour taint producing streptomycetes isolated from barramundi ponds

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.

Quantification of novel geosmin-producing bacteria in aquaculture systems

, 2017
Earthy off-flavour, caused by geosmin, constitutes an economic problem in recirculating aquaculture systems (RAS). Cyanobacteria, Streptomyces and myxobacteria are thought to be the main geosmin-producing bacteria in aquatic systems.
