Disease relevance of CCRIS 6593

Bacterial groups within Actinobacteria produce the odours geosmin and 2-methylisoborneol, which lower the quality of surface water when used for drinking [1].
2-Methylisoborneol (MIB), a metabolite of blue-green algae, has been implicated in causing unpalatable drinking water throughout the world [2].
These data suggest that 2-methylisoborneol can be transformed by Pseudomonas spp. and the test adopted by this study can be applied for screening organisms for their ability to transform MIB [3].
Production of 2-methylisoborneol by Streptomyces violaceusniger and its transformation by selected species of Pseudomonas [3].

High impact information on CCRIS 6593

The selectivity of the LTGC is demonstrated by the extraction of a variety of aromatic hydrocarbons as well as the taste and odor contaminants geosmin, 2-methylisoborneol, and 2,4,6-trichloroanisole commonly found in water supplies [4].
An automated technique based on purge-and-trap coupled to gas chromatography with mass spectrometric detection has been developed and optimized for the trace determination of five of the most important water odorants; 2-isopropyl-3-methoxypyrazine, 2-isobutyl-3-methoxypyrazine, 2-methylisoborneol, 2,4,6-trichloroanisole and geosmin [5].
Concentrations of geosmin and 2-methylisoborneol as low as 0.001 microg/kg were detected in SIM mode using ion trap mass spectrometer [6].
The diethyl ether fraction showed selective activity against the cyanobacterium responsible for the 2-methylisoborneol-induced off-flavor sometimes associated with catfish farming operations [7].
The effect of glucose, glycerol and yeast-extract (YE) on 2-methylisoborneol (MIB) production by Streptomyces violaceusniger (C4-S strain) was determined [3].

Anatomical context of CCRIS 6593

Toxicological effects of geosmin and 2-methylisoborneol on rainbow trout hepatocytes [8].

Gene context of CCRIS 6593

One of the most common and problematic types of taste and odour is the earthy/musty odour produced by geosmin (trans-1, 10-dimethyl-trans-9-decalol) and MIB (2-methylisoborneol) [9].

Analytical, diagnostic and therapeutic context of CCRIS 6593

Biodegradation rates of 2-methylisoborneol (MIB) and geosmin through sand filters and in bioreactors [10].
Removal of geosmin and 2-methylisoborneol by biological filtration [9].
