Figure S1. Maximum likelihood tree of representative sequences from dominant OTUs in the NIC enrichments MCC and wheat arabinoxylan as uncovered in (1) Sanger-based passage 4 DNA and cDNA clone libraries at passage 4, (2) SSU amplicon sequencing of passage 4 (described as 454_OTU97_#) and (3) high-resolution of MCC-adapted thermophilic passage (described as TC_OTU97_#). The tree is based on the 16S rRNA gene using sequences (ca. 800 bp) obtained from and environmental clones. Small SSU amplicon sequences (454_OTU97_#) were quick added to the tree with parsimony.


Figure S2. Differential endoglucanase activity for thermophilic consortia adapted to microcrystalline cellulose (mcc) and wheat arabinoxylan (xylan) on filter sterilized (0.2 μm filter) supernatant (fs), unfiltered whole cells (wc) and sonicated cells (son).


Figure S3. Glycosyl hydrolase activities during the establishment of the thermophilic, microcrystalline cellulose Picture depicts the colorometric changes noted during the development of this consortia.


Figure S4. Relationship between the relative abundance of Bacteroidetes (A), Firmicutes (B) and Thermus (C) based on SSU amplicon libraries and CrI using X-ray diffraction. Starting crystallinity of the cellulose prior to microbial transformation is depicted with an arrow in each panel.


Figure S5. Experimental design of the establishment for the thermophilic consortia (A) and high-resolution analysis of the MCC-adapted thermophilic consortia within a passage (B).
