Microbiota of BSG during 90days spontaneous and guided SSF. Fungal and Bacterial communities of raw brewers' spent grains during 90-days spontaneous and guided solid state fermentations

The evolution of the spontaneous microbiota of freshly collected brewers' spent grains (i.e. spontaneous solid state fermentation), and that of brewers' spent grains inoculated with a commercial "plant-growth promoting" microorganism preparation (guided solid state fermentation), was followed at days 0, 7, 14, 28, 56, 70 and 90 by 16S-rRNA(V3-V4) and ITS2 high throughput sequencing (Illumina Miseq).
