Statistics of the four metagenomic data sets derived after quality trimming from samples of a water kefir fermentation process as a function of time.

Sample	Metagenome size [Mbp]	Number of reads	Median read length [bp]
L24	438	2,397,600	208
G24	521	2,902,164	198
L72	457	2,239,269	225
G72	445	2,640,708	184
TOTAL	1864	10,194,026	205

The first letter in the sample code stands for the sample type, namely water kefir liquor (L) or water kefir grains (G). The Arab numbers stand for the sampling time point (sample taken after 24 h or 72 h of fermentation).
