Isolation, identification and odour-producing abilities of geosmin/2-MIB in actinomycetes from sediments in Lake Lotus, China [PDF]
, 2009 This study aimed to determine whether actinomycetes could contribute to the odours occurring in Lake Lotus, China. In total, 55 actinomycete strains were isolated from sediments in Lake Lotus and their odorous metabolites, geosmin and 2-methylisoborneol (

Characteristics and Mechanism of 2-MIB Removal by a Biological Filtration.
Journal of Japan Society on Water Environment, 2001 Experimental studies on the removal of natural and artificial 2-MIB in the surface water of Lake Biwa were conducted using a biological filter pilot plant with porous granular ceramic media. Microbiological and biochemical studies on the mechanism of bio-degradation of 2-MIB were also conducted.From the results of a series of the pilot plant study, the

Gongye shui chuli, 2022 二甲基异莰醇（2-MIB）和土臭素（GSM）等嗅味物质引起的饮用水嗅味问题是供水行业普遍关注的热点问题。围绕水中2-MIB和GSM的有效去除，研究了亚硫酸氢钠（BS）活化高锰酸钾（PM）对两种物质的氧化降解特性，优化了PM/BS体系的药剂投加方式，解析了常见水质因子对PM/BS体系去除2-MIB和GSM效果的影响。结果表明，PM/BS体系能有效氧化去除水中的2-MIB和GSM，但加药方式、药剂浓度比和PM投加量对氧化效果具有显著影响，多次投加比单次集中投加更有利于2-MIB和GSM的氧化去除 ...

Gongye shui chuli, 2021 研究了粉末活性炭（PAC）主要性能指标对其吸附去除水中2-甲基异莰醇（2-MIB）和土臭素（GSM）效能的影响。结果表明，影响2-MIB和GSM吸附量的主要因素是活性炭特定孔径区间的比表面积，其中，2-MIB和GSM吸附量分别与1.0~1.2 nm、0.64~1.0 nm孔径区间的比表面积显著相关；活性炭碘值与2-MIB吸附量及1.0~1.2 nm孔径区间的比表面积均具有良好的一致性，可以作为衡量2-MIB吸附量的参考指标。本研究结果可为供水企业选购PAC用于应对水源季节性嗅味问题提供技术参考。

Comparison between ozone and ferrate in oxidising geosmin and 2-MIB in water
Water Science and Technology, 2007 Among the chemicals causing taste and odour (T&O) in drinking water, the most commonly identified and problematic ones are geosmin and 2-MIB (2-methylisoborneol). Since the reported odour thresholds of geosmin and 2-MIB are as low as 4 and 8.5 ng/L, respectively, they are not readily removed by conventional water treatment processes. In this study,

Journal of Analytical Methods in Chemistry, 2014 This study was conducted to obtain the basic data of two common odorants—geosmin and 2-methylisoborneol (GSM and 2-MIB)—in environmental water. More specifically, the headspace solid-phase microextraction coupled to gas chromatography mass spectrometry ...
