Photocatalytic degradation of geosmin: Reaction pathway analysis
Water SA, 2012 The presence of geosmin in drinking water imparts a musty odour which leads to consumer complaints. Geosmin and other unwanted organics can be treated using photocatalysis. However, the intermediates formed during the photocatalytic degradation process and their degradation pathways have not previously been described.

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.

Ultrasonically induced degradation of 2-methylisoborneol and geosmin [PDF]
Water Research, 2007 2-Methylisoborneol (MIB) and geosmin (GSM) are taste and odor compounds produced by cyanobacteria in surface waters. While the strong odors and musty flavors of MIB and GSM are generally associated with poor water quality, the removal of these semi-volatile compounds presents a significant challenge to drinking water providers. Likewise in aquaculture,

Insights from the draft genome of the subsection V (Stigonematales) cyanobacterium Hapalosiphon sp. Strain MRB220 associated with 2-MIB production [PDF]
, 2016 A non-axenic unialgal culture containing a Subsection V (Stigonematales) cyanobacterium, Hapalosiphon strain MRB 220, was obtained from a benthic freshwater algal mat through multiple transfers following growth in sterile media.

Characterisation of the aroma of green mexican coffee and identification of mouldy/earthy defect [PDF]
, 2001 Erworben im Rahmen der Schweizer Nationallizenzen (http://www.nationallizenzen.ch)The aromas of a reference green Mexican coffee (Arabica) and of a coffee from the same origin, but having a pronounced earthy/mouldy off-taint, were characterised.

Management of Biesboch reservoirs for quality control with special reference to eutrophication [PDF]
, 1992 The three Biesbosch Reservoirs are pumped storage reservoirs, fed with rather polluted and highly eutrophic water from the River Meuse. Air injection at the bottom of the reservoirs prevents thermal stratification, which would otherwise result in serious

Endogenous Production of Geosmin in Table Beet [PDF]
HortScience, 2018 The earthy flavor of table beet is due to an aromatic terpene derivative called geosmin. It has been hypothesized that geosmin presence in beet is due to geosmin-producing bacteria such as Streptomyces spp. that exist in the soil. However, recent findings suggest that beet may produce geosmin endogenously without microbial influence.

Chemistry – A European Journal, EarlyView.The mechanism of pacifigorgiadiene synthase from Burkholderia gladioli was investigated through isotopic labeling experiments and DFT calculations. The results revealed an unexpected labeling pattern which appeared to be different in the main and the side products, requiring unprecedented mechanistic explanations, including a “break‐flip‐cyclise ...

, 2020 Off-flavour described as ‘earthy-musty’ is commonly reported in fish raised in land-based aquaculture systems. Bioconcentration in fish of lipophilic geosmin produced by microbiota is regarded as the most important cause for this off-flavour. Despite that off-flavour in fish is an extensively studied and well documented problem, satisfactory solutions ...
