Biodegradation of a Musty Odour Component, 2-Methylisoborneol

Water Research, 1996
Two different types of bacteria were isolated from the backwash water of a pilot plant of biological filter at Lake Biwa (Japan). Two strains of the bacteria belonging to Pseudomonas sp. and Enterobacter sp. degraded 2-methylisoborneol (2-MIB) to afford 2-methylcamphene and 2-methylenebornane as the dehydration products, and another one belonging to ...

On the Role of (−)-2-Methylisoborneol for the Aroma of Robusta Coffee

Journal of Agricultural and Food Chemistry, 2002
The role of 2-methylisoborneol (MIB) in coffee aroma is controversially discussed in the literature. MIB is known as an off-flavor compound in drinking water and food, but it has also been suggested as a key flavor component of Robusta coffee, discriminating Robusta from Arabica coffee.

Properties of Activated Carbon Controlling 2-Methylisoborneol Adsorption

Carbon, 1997
2-Methylisoborneol (MIB) is one of the most common taste and odour molecules found in water supplies. The use of activated carbons is known to be effective in removing MIB from water. In this work, it was found that the selection of an appropriate carbon for removing MIB from water depends on the carbon surface hydrophilicity, which can be determined ...

Tailored GAC for the Effective Control of 2‐Methylisoborneol

Journal AWWA, 2005
Rapid small‐scale column tests were used to compare virgin, conventionally reactivated, and steam‐pyrolysis reactivated granular activated carbons (GACs) for their performance in removing 2‐methylisoborneol (MIB) and their ability to retain MIB when the odor episode subsided.

Interactions between 2-methylisoborneol and C-phycocyanin: Binding site analysis and effects of complexation on 2-methylisoborneol oxidation

Water Research
2-Methylisoborneol (2-MIB), predominantly produced by cyanobacteria in drinking water sources, is a major off-flavor compound responsible for earthy-musty odors at extremely low concentrations. Recent evidence suggests that a substantial fraction of 2-MIB exists in a bound state associated with algal-derived proteins, yet the mechanism governing this ...

Seasonal occurrence and degradation of 2-methylisoborneol in water supply reservoirs

Water Research, 2005
Methylisoborneol (MIB) and geosmin are cyanobacterial metabolites that occur at nanograms per liter levels in surface water supplies and are responsible for many taste and odor complaints about the aesthetics of drinking water. This study evaluated three water supply reservoirs with bottom-release (hypolimnion) outlet structures in Arizona.

Efficiency and Products Investigations on the Ozonation of 2‐Methylisoborneol in Drinking Water

Water Environment Research, 2009
2‐Methylisoborneol (MIB) is a terpenoid produced as a secondary metabolite by some cyanobacteria and actinomycetes and thus can be present in some drinking water source waters. The removal efficiency, products, and degradation pathway of MIB in drinking water by ozonation were studied.

Toxicological Effects of Geosmin and 2-Methylisoborneol on Rainbow Trout Hepatocytes

Bulletin of Environmental Contamination and Toxicology, 1999
Geosmin (GM) and 2-methylisoborneol (MIB) are produced by actinomycetes and cyanophytes in the aquatic environment (Gerber 1979; Slater and Block 1983; Persson 1988). These compounds occur in lakes, reservoirs and rivers where GM is more likely to be produced in the water column while MIB is more likely to be produced in sediments (Slater and Blok 1983;

The critical trigger of 2-methylisoborneol in Taihu Lake: Flow velocity

Water Research
The dynamics of 2-methylisoborneol (2-MIB), a terpene-derived odorant that compromises drinking water safety worldwide, in drinking water sources are influenced by multiple environmental factors. However, the primary driver triggering its peaks has remained elusive, limiting predictive capability and effective management.

[Removal of 2-methylisoborneol in drinking water by ozonation].

Huan jing ke xue= Huanjing kexue, 2008
The removal efficiencies of 2-methylisoborneol(MIB) by KMnO4, NaClO, H2O2, O3 were compared, and it was found that ozone was the most effective oxidant for MIB removal. By investigating the factors of the removal of MIB by ozone, it was found that the removal of MIB increased with pH increase.
