The biosynthesis of the odorant 2-methylisoborneol is compartmentalized inside a protein shell [PDF]
Nature CommunicationsTerpenoids are the largest class of natural products, found across all domains of life. One of the most abundant bacterial terpenoids is the volatile odorant 2-methylisoborneol (2-MIB), partially responsible for the earthy smell of soil and musty taste ...

Biotransformations of 2-Methylisoborneol by Camphor-Degrading Bacteria [PDF]
Applied and Environmental Microbiology, 2009 ABSTRACTMany camphor-degrading bacteria that are able to transform 2-methylisoborneol (2-MIB) have been identified. Three of these strains have been examined in detail.Rhodococcus ruberT1 metabolizes camphor through 6-hydroxycamphor but converts 2-MIB to 3-hydroxy-2-MIB.Pseudomonas putidaG1, which metabolizes camphor through 5-hydroxycamphor, converts ...

Genes associated with 2-methylisoborneol biosynthesis in cyanobacteria: isolation, characterization, and expression in response to light. [PDF]
PLoS ONE, 2011 The volatile microbial metabolite 2-methylisoborneol (2-MIB) is a root cause of taste and odor issues in freshwater. Although current evidence suggests that 2-MIB is not toxic, this compound degrades water quality and presents problems for water ...

Biosynthesis of 2-Methylisoborneol in Cyanobacteria [PDF]
Environmental Science & Technology, 2010 The production of odiferous metabolites, such as 2-methlyisoborneol (MIB), is a major concern for water utilities worldwide. Although MIB has no known biological function, the presence of the earthy/musty taste and odor attributed to this compound result in the reporting of numerous complaints by consumers, which undermines water utility performance ...

Bacterial Degradation of 2-Methylisoborneol
Water Science and Technology, 1988 2-Methylisoborneol (MIB) is a musty-odored compound occurring in natural waters that is difficult to remove by conventional water treatment methods. Biodegra-dation may be an alternative for its removal from drinking water. Studies were undertaken to determine the conditions enhancing MIB degradation and to isolate and identify the bacteria responsible.

Effect of Culture Temperature on 2-Methylisoborneol Production and Gene Expression in Two Strains of Pseudanabaena sp. [PDF]
CellsThe presence of the odorant 2-methylisoborneol (2-MIB) in drinking water sources is undesirable. Although 2-MIB production is known to be influenced by temperature, its regulation at the gene level and its relationship with Chlorophyll-a (Chl-a) at ...

A Simple Alternative Method for Preservation of 2-Methylisoborneol in Water Samples [PDF]
International Journal of Environmental Research and Public Health, 2018 2-Methylisoborneol (2-MIB) is one of the most commonly observed taste and odor (T&O) compounds present in drinking water sources. As it is biodegradable, a preservation agent, typically mercury chloride, is needed if the water is not analyzed right after sampling.
