Geosmin and 2-methylisoborneol production in a major aqueduct system

Water Science and Technology, 1995
The California Aqueduct supplies water from Northern California to Southern California, dividing into the West and East branches above Pyramid Lake. In July and August 1990, elevated geosmin levels (10-48 ng/l) occurred in the East Branch of the aqueduct, which extends along the southern edge of the Mojave Desert.

Harmful and Harmless Soil-Dwelling Fungi Indicate Microhabitat Suitability for Off-Host Ixodid Ticks

Microorganisms
Following blood meals or questing bouts, hard ticks (Ixodidae) must locate moist off-host microhabitats as refuge. Soil-dwelling fungi, including entomopathogenic Beauveria bassiana (Bb), thrive in moist microhabitats.

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, Volume 57, Issue 2, April 2026.
Abstract 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‐size Atlantic salmon.

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

Water Environment Research, Volume 98, Issue 3, March 2026.
This 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.

Interlaboratory comparison of geosmin and 2-methylisoborneol in municipal tap water

Water Science and Technology, 2007
An interlaboratory comparison (“round-robin”) for geosmin and 2-methylisoborneol (MIB) was carried out between six laboratories of the Ontario Water Works Research Consortium (OWWRC). Municipal tap water was found to be a suitable medium for distribution of samples. To test stability, geosmin and MIB were added to tap water and stored at 2–4°C.

Biodegradation of 2-Methylisoborneol by Oligotrophic Bacterium Isolated from a Eutrophied Lake

, 1992
2-Methylisoborneol (MIB) is one of several causative compounds responsible for musty odor problems of drinking water. The purpose of this study was to investigate the kinetics of MIB biodegradation and utilization of other organics by Bacillus sp.

Strukturrevision des C16‐Sesquiterpens Hegelenether und der Mechanismus der C6‐Methylierung in der Terpenbiosynthese

Angewandte Chemie, Volume 138, Issue 9, 23 February 2026.
Die Struktur des nicht‐kanonischen C16‐Sesquiterpens Hegelenether wurde zur Struktur von Marxdiol revidiert und seine absolute Konfiguration bestimmt. Isotopenmarkierungsexperimente klärten den stereochemischen Verlauf der an seiner Biosynthese beteiligten Methyltransferase auf.

The Drinking Water Taste and Odor Wheel for the Millennium: Beyond Geosmin and 2-Methylisoborneol

, 1999
The “Taste and Odor Wheel” developed over the last 15 years has been updated to include new compounds identified in the eight classes of odorants, four tastes, and one mouth feel/nose feel category.

Structural Revision of the C16 Sesquiterpene Hegelenether and the Mechanism of C6‐Methylation in Terpene Biosynthesis

Angewandte Chemie International Edition, Volume 65, Issue 9, 23 February 2026.
The 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.
