geosmin, a sesquiterpenoid metabolite produced by soil living fungi. Some food commodities are liable to contamination by geosmin producing fungi. Under favourable environmental conditions the production of geosmin occurs. One of the producers of geosmin in fruits is Penicillium expansum which also produces the mycotoxin patulin. Recent reports indicate that geosmin production by P. expansum is stimulated by Botrytis cinerea.
A geode is a type of rock formation that occurs when a pocket of air or gas is trapped and forms a cavity in sedimentary or igneous rock. A hard crust forms around the outside of the cavity.Groundwater, which often carries dissolved minerals in solution, seeps through the rock over a long period of time.lear quartz, smoky quartz, amethyst, calcite, celestite, and chalcedony are examples of some minerals you may find inside a geode. Geodes from the same location often have the same type of mineral crystals. Some geodes are filled in with beautiful layers of mineral crystals.
