Earthy-musty Odour and Off-flavour Taints in Phayao Lake, Thailand
This study aimed to determine and monitor the levels of earthy-musty odour in Phayao Lake water and the microbiota responsible for the production of odorous compounds, geosmin and 2-methylisoboneol. Geosmin was identified as the main odorous substance in both water and lake sediments. It was signifi...
