List of significantly operational taxonomic units (OTUs) affected in inverted light compared to sleep control.

OTUs*	Phylum	Family	Genus	Fitted Ratio IN/CL (Day 49)	ANOVA (p-value)
10	Bacteroidetes	Porphyromonadaceae	Barnesiella	2.29	0.0002
16	Firmicutes	Ruminococcaceae	Clostridium_IV	1.47	0.0008
17	Firmicutes	Erysipelotrichaceae	Turicibacter	0.58	0.002
18	Firmicutes	Lachnospiraceae	Clostridium_XlVb	3.16	3.16E-06
19	Firmicutes	Lactobacillaceae	Lactobacillus	9.6	0.001
22	Firmicutes	Ruminococcaceae	Pseudoflavonifractor	3.44	8.52E-06

^*OTUs unambiguously classified to the genus level were selected. The OTU abundances were used to calculate distances between samples using Bray–Curtis dissimilarity measure.
