There is provided a novel microorganism capable of fermentation without placing particular limitations on fermentation conditions, as well as a method of processing green coffee beans using the novel microorganism, the method adding new, high-quality flavor and aroma to a coffee beverage by a simple operation, without instigating a particular increase in raw material costs and without requiring a new processing step. The method for processing green coffee beans includes a fermentation step of bringing nutritive substances and microorganisms into contact with one another and causing fermentation in the presence of green coffee beans, wherein the microorganism used in the fermentation step is a microorganism belonging to the genus Geotrichum.

1. A method for processing green coffee beans comprising a fermentation step: bringing nutritive substances and an isolated microorganism into contact with one another at a temperature of 15 to 30° C. to perform fermentation in the presence of green coffee beans, wherein the isolated microorganism in the fermentation step is a microorganism belonging to the genus Geotrichum, wherein the fermentation step is carried out by bringing the isolated microorganism into direct contact with coffee cherries, and wherein the isolated microorganism belonging to the genus Geotrichum is selected from the group consisting of Geotrichum candidum (IAM 12700, GEO CA (item no. 200691), GEO CB (items no. 200692), GEO CD1 (item no. 200693), and GEO CE (item no. 200835)), Geotrichum rectangulatum (JCM 1750), Geotrichum klebahnii (JCM 2171), and a new strain of the Geotrichum sp. having the international deposit number FERM BP-10300. 2. Green coffee beans obtained by the method of claim 1. 3. Roasted coffee beans obtained by performing a roasting process on the green coffee beans according to claim 2. 4. A coffee beverage obtained by adding the roasted coffee beans according to claim 3 as a raw material. 5. A new isolated strain of the Geotrichum sp. having the international deposit number FERM BP-10300. 6. A method for processing green coffee beans comprising a fermentation step comprising: bringing nutritive substances and an isolated microorganism into contact with one another at a temperature of 15 to 30° C. to perform fermentation in the presence of a green coffee bean,wherein the isolated microorganism added to the fermentation step is a microorganism belonging to the genus Geotrichum, wherein the green coffee bean is located within a coffee cherry,wherein the nutritive substances include a coffee pulp contained within the coffee cherry, andwherein the isolated microorganism belonging to the genus Geotrichum is selected from the group consisting of Geotrichum candidum (IAM 12700, GEO CA (item no. 200691), GEO CB (items no. 200692), GEO CD1 (item no. 200693), and GEO CE (item no. 200835)), Geotrichum rectangulatum (JCM 1750), Geotrichum klebahnii (JCM 2171), and a new strain of the Geotrichum sp. having the international deposit number FERM BP-10300.
