New strategies for mitigating undesirable odors connected to geosmin and 2-MIB in minced fish muscle: a model system approach [PDF]
Scientific ReportsFreshwater fish species commonly suffer from muddy odor problems linked to geosmin and 2-methylisoborneol (2-MIB). This study examined whether the release of geosmin and 2-MIB from spiked fish muscle could be reduced by adding poly-/oligosaccharides ...

The effect of oxidants on 2-MIB concentration with the presence of cyanobacteria
Water Science and Technology, 2004 In this study, the effect of three oxidants, sodium hypochlorite, potassium permanganate, and ozone, were tested for the removal of 2-MIB with presence of cyanobacteria. Algae in water samples from the source water of Feng-Shen waterworks (FSW), Taiwan were cultivated at 30¡C with continuous light at an intensity between 2,500 and 3,400 lux. During the

Cnb proteins affect the intracellular 2-MIB retention in heterologous gene expression systems [PDF]
Archives of Microbiology2-methylisoborneol (2-MIB) is one of the main cyanobacterial metabolites responsible for unpleasant taste and odor in drinking water. 2-MIB biosynthesis involves a two-step enzymatic reaction catalyzed by enzymes encoded by the mtf and mtc genes. Two homologous genes, cnbA and cnbB, which encode cyclic nucleotide-binding proteins of unknown function ...

Bacterial Geosmin Biosynthesis is Compartmentalized Inside a Two‐Component Protein Shell [PDF]
Advanced Science, EarlyView.This study reports the discovery that geosmin biosynthesis is compartmentalized inside a two‐component protein shell in many bacteria. Sequestration of geosmin synthase inside a Family 2B encapsulin nanocompartment improves geosmin yield and increases enzyme stability as compared to the free enzyme.

Managing the Taste and Odor Compound 2-MIB in a River-Reservoir System, South Korea
Water, 2023 High concentrations of 2-methylisoborneol (2-MIB) were reported during winter in the Paldang reservoir and North Han River, South Korea. The causes of the unusual taste and odor problems in the regulated river-reservoir system were not understood; however, a short-term solution is to flush out 2-MIB-rich water to secure water sources for over 20 ...

pH and Mg/Ca control for biological treatment of an offensive flavour (2-MIB)
Water Science and Technology, 1998 From a series of experimental observations, it was found that removal rates of the offensive flavor 2-methyl-isoborneol(2-MIB) and ammonia by a biological treatment for water supply were rather unstable and that the removal rates of them often became reverse such as low removal in 2-MIB and high removal of ammonia. One reason for the reverse phenomenon

DEVELOPMENT OF REMOVAL EFFICIENCY-DRIVEN MULTIPLE REGRESSION MODELS FOR 2-MIB AND GEOSMIN PREDICTION
Konya Journal of Engineering Sciences2-Methylisoborneol (2-MIB) and geosmin, two primary taste and odor compounds in drinking water, cause significant quality concerns due to their algal origin and extremely low odor thresholds. This study aims to develop multiple linear regression (MLR) models to estimate 2-MIB and geosmin concentrations using total organic carbon (TOC) and chlorophyll-a

Temporal and Spatial Distribution of Geosmin and 2-MIB in the Daecheong Reservoir [PDF]
Korean Journal of Environmental Agriculture, 2015 Abstract BACKGROUND: Contamination of source water by odorous compounds are one of the problems related to the water quality management, especially in Korea where surface water is used as drinking water. Geosmin (1, 10- trans -dimethyl- trans -9-decalol) and 2-MIB (2-methyl isoborneol : 1,2,7,7-tetramethyl-exo-bicycloheptan-2-ol) are commonly ...

Producers and drivers of odor compounds in a large drinking-water source
Frontiers in Ecology and Evolution, 2023 IntroductionTaste and odor (T&O) problems have been affecting drinking water safety. As a eutrophicated drinking water reservoir in Tianjin city, the Yuqiao Reservoir was threatened by 2-MIB and geosmin in recent years.MethodsIn this study, quantile ...
