Biocontrol of Geosmin Production by Inoculation of Native Microbiota during the Daqu-Making Process

Fermentation, 2022
Geosmin produced by Streptomyces can cause an earthy off-flavor at trace levels, seriously deteriorating the quality of Chinese liquor. Geosmin was detected during the Daqu (Chinese liquor fermentation starter)-making process, which is a multi-species ...

Driving Factors of Geosmin Appearance in a Mediterranean River Basin: The Ter River Case

Frontiers in Microbiology, 2021
In recent decades, human activity coupled with climate change has led to a deterioration in the quality of surface freshwater. This has been related to an increase in the appearance of algal blooms, which can produce organic compounds that can be toxic ...

Modeling geosmin removal in a full-scale filter [PDF]

Anais da Academia Brasileira de Ciências, 2020
Taste and odor compounds affect drinking water safety perception and may drive consumers to less secure water sources. Adsorption, using powered activated carbon, is the most common method to remove these compounds but greatly increases the amount of ...

Geosmin Attracts Aedes aegypti Mosquitoes to Oviposition Sites

, 2020
Geosmin is one of the most recognizable and common microbial smells on the planet. Some insects, like mosquitoes, require microbial-rich environments for their progeny, whereas for other insects such microbes may prove dangerous.

Photocatalytic destruction of geosmin using novel pelleted titanium dioxide [PDF]

, 2008
Geosmin is produced by cyanobacteria and actinomycetes in surface waters. It causes undesirable earthy off-flavours in freshwater fish and is a major concern for the drinking water industry. This paper presents the first published study on the use of the
