Modeling geosmin removal in a full-scale filter [PDF]
Anais da Academia Brasileira de Ciências, 2020 Taste and odor compounds affect drinking water safety perception and may drive consumers to less secure water sources. Adsorption, using powered activated carbon, is the most common method to remove these compounds but greatly increases the amount of ...

Estimating Operational Costs of Activated Carbon for Water Treatment Plants by Predicting the Rise of Harmful Algal Blooms Under Climate Change in Korea Using Machine Learning. [PDF]
Water Environ ResThis study investigated future operational costs in water treatment (WT) plants. Random forest modeling projected 3–5 times more abundant cyanobacteria by 2100 due to climate change. Increased microcystins demanded substantially more activated carbon and, as a result, WT costs could rise to $6–22/household/month.

Influence of Temperature Regimes on the Production of 2-MIB and Geosmin by Pseudanabaena galeata and Phormidium ambiguum. [PDF]
Water Environ ResTwo cyanobacteria species Pseudanabaena galeata and Phormidium ambiguum were exposed to 20°C, 30°C, and 40°C for a 10‐day period, and samples were taken every other day for a 10‐day period. Both species showed significant changes in odor compound production at different temperature regimes.

A Detailed View on Geosmin Biosynthesis
ChemBioChem, 2023 AbstractThe 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 reaction is unknown. This article reports on a deep investigation of the mechanism of geosmin

Structural Revision of the C<sub>16</sub> Sesquiterpene Hegelenether and the Mechanism of C6-Methylation in Terpene Biosynthesis. [PDF]
Angew Chem Int Ed EnglThe structure of the non‐canonical C16 sesquiterpene named hegelenether was revised to the structure of marxdiol, and its absolute configuration was assigned. Isotopic labeling experiments revealed the stereochemical course of the methyltransferase involved in its biosynthesis.

Accumulation of Geosmin and 2-methylisoborneol in European Whitefish Coregonus Lavaretus and Rainbow Trout Oncorhynchus Mykiss in RAS [PDF]
, 2020 Geosmin (GSM) and 2-methylisoborneol (MIB)-induced off-flavors can cause serious problems in a recirculating aquaculture system (RAS), such as delayed harvest and increased production costs, but also damage producers’ reputation.

Geosmin Biosynthesis. Mechanism of the Fragmentation−Rearrangement in the Conversion of Germacradienol to Geosmin [PDF]
Journal of the American Chemical Society, 2007 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), octalin 5, and acetone, which was trapped as 2,2-dimethylthiazolidine (9) by reaction with cysteamine.
