Geosmin(土臭素)是一种由特定微生物产生的挥发性有机化合物,具有强烈的泥土气味,广泛存在于水体、土壤及水产中,对饮用水、水产养殖和香料制造有重要影响。其特性、来源、环境关系及处理方法如下: 特性与命名 土臭素化学名称为geosmin,曾误译为“地霉素”,正确译名为“土臭素”或“土腥味素”。...
Geosmin, from the ancient Greek geo (earth, ground) and osmḗ (odour), is an aromatic compound that smells of damp soil. It gives beets their earthy taste and springs their ‘nature-full’ scent. Dormant in the ground, it can be reactivated by rainfall and fill the air. The human no...
Because these bacteria thrive in wet conditions and produce spores during dry spells, the smell of geosmin is often most pronounced when it rains for the first time in a while, because the largest supply of spores has collected in the soil. 这气味就和在自家花园翻土时闻到的一样 。 " ...

Geosmin was first discovered as product of cyanobacteria by Safferman et al. (1967) and MIB by Tabachek and Yurkowski (1976). In the last two decades, many new cyanobacteria species have been shown to produce geosmin and MIB (e.g. Izaguirre et al., 1982; Izaguirre, 1992; Hosaka et ...
Intriguingly, geosmin and 2-MIB are not universally compelling for arthropods. Drosophila melanogaster (fruit flies) are repelled by geosmin (Melo et al., 2020) and by high levels of 2-MIB (Fig. 4), although lower levels are associated with slight attraction (Ho et al., 2020). Notably,...
