Ikaite, along with alpha sulfur, precipitates in and on the bacterial slime flux jelly. The tree wound consists of infected wood, called wetwood that exudes a nutrient-rich water on which a jelly-like slime flux forms. Here is described the serendipitous discovery of ikaite on a tree (Populus fremontii) wound from the hot Sonoran Desert, which precipitates during short cold periods in the winter, whereas monohydrocalcite forms through most of the year. Other trees and shrubs: slime flux and a similar phenomenon called bacterial wetwood are also found quite frequently on the stems of a wide range of trees and shrubs. The biology is similar to that of clematis slime flux, although it is thought that in trees the bacteria most usually colonise the plant through the roots. Weeping and fluxing from patches on the trunk is often the only symptom, but branch dieback may occur.Ikaite is the calcium carbonate hexahydrate (CaCO 3♶H 2O), which precipitates below ~ 7 ☌, first identified from Ikka Fjord in southwest Greenland and subsequently more widely reported. The bacteria penetrate deep into the stem tissues, and when the sugary sap rises in spring this is fermented by the bacteria to produce the foul-smelling slime. Gasses are also produced which force the slime out under pressure and may result in further stem splitting. A range of bacterial species, as well as other organisms such as yeasts and fungi, are often found within the slime, all taking advantage of the sugars within the sap. Infection may also sometimes occur through the root system.Any type of mechanical damage (including strong winds twisting the stems).
