\textit{Verrucomicrobia}, a cosmopolitan soil phylum often found in high abundance \cite{Fierer_2013}, are implicated in polysaccaride degradation in many environments \cite{Fierer_2013,Herlemann_2013,10543821}. \textit{Verrucomicrobia} comprise 16\% of the total cellulose responder OTUs detected. 40\% of \textit{Verrucomicrobia} responders belong to the uncultured FukuN18 family originally identified in freshwater lakes \cite{Parveen_2013}. The \textit{Verrucomicrobia} OTU with the strongest \textit{Verrucomicrobial} response to $^{13}$C-cellulose shared high sequence identity (97\%) with an isolate from Norway tundra soil \cite{Jiang_2011} although growth on cellulose was not assessed for this isolate. Only one other $^{13}$C-cellulose responding verrucomicrobium shared high DNA sequence identity with a sequenced type strain, OTU.638 with \textit{Roseimicrobium gellanilyticum} (100\% sequence identity) and \textit{Roseimicrobium gellanilyticum} grows on soluble celluose \cite{Otsuka_2012}. The remaining $^{13}$C-cellulose \textit{Verrucomicrobia} responders did not share high sequence identity with any type strains (maximum sequence identity with any type strain 93\%).   \textit{Chloroflexi} are traditionally known for their metabolically dynamic lifestyles ranging from anoxygenic phototropy to organohalide respiration \cite{Hug_2013}. Recent studies have focused on \textit{Chloroflexi} roles in C cycling \cite{Hug_2013,Goldfarb_2011,Cole_2013} \cite{Hug_2013, Goldfarb_2011,Cole_2013}  and several members of this phylum demonstrated cellulose utilization \cite{Goldfarb_2011,Cole_2013,Hug_2013}. \cite{Goldfarb_2011, Cole_2013, Hug_2013}.  Four closely related OTUs in an undescribed \textit{Chloroflexi} lineage (closest matching type strain for all four OTUs: \textit{Herpetosiphon geysericola), 89 geysericola}, 89\%  sequence identity) responded to $^{13}$C-cellulose in this microcosm experiment. One additional OTU also from a poorly characterized lineage (closest type strain match a proteobacterium at 78\% sequence identity) responded to $^{13}$C-cellulose. One of the most interesting findings is a single Cyanobacterial responder OTU, which exhibit the third greatest enrichment measured (l2fc = 3.35) in response to \textsuperscript{13}C-cellulose assimilation. This OTU falls into the recently described candidate phylum Melainabacteria \cite{Di_Rienzi_2013}, although its phylogenetic position is debated \cite{Soo_2014}. More importantly, the catalog of metabolic capabilities associated with Cyanobacteria are quickly expanding \cite{Di_Rienzi_2013, Soo_2014}. Our findings provide evidence of cellulose degradation for Melainabacteria, supporting hypothesized polysaccharide degradation suggested by genomic analysis \cite{Di_Rienzi_2013}.
