The present invention relates to a method for preparing a fecal 5 microbiota sample of a donor subject. Said method includes the following steps: a) collecting at least one fecal microbiota sample from the donor subject; b) within a period of less than 5 minutes after collecting the sample, placing said sample obtained in step a) in an oxygen-tight collection device; c) mixing the sample obtained in step b) with at least one aqueous saline 10 solution containing at least one cryoprotectant and/or a filling agent; d) optionally, filtering the mixture obtained in step c), in particular by means of a filter comprising pores having a diameter of less than or equal to 0.7 mm, preferably less than or equal to 0.5 mm; and e) storing the mixture obtained in step c) or d) by freezing said mixture at a temperature 15 of between &#x2212;15&#xb0; C. and &#x2212;100&#xb0; C. Steps b) to e) are carried out in anaerobiosis.

Method of preparing a faecal microbiota sample

Method for lyophilisation of a simple of fecal microbiota. The present invention relates to a method for lyophilisation of a sample of fecal microbiota from a donor subject, comprising the following steps: A) mixing of a sample of fecal microbiota from a donor subject with a diluent selected from polyols, disaccharides to pentasaccharides, maltodextrins and mixtures thereof, and B) freezing the mixture obtained in A) at a temperature of less than &#x2212;50&#xb0; C., preferably of between &#x2212;70&#xb0; C. and &#x2212;100&#xb0; C., followed by the lyophilisation thereof.
