Ciliate protsis are abundant in soils and other terrestrial environments, but their roles in nutrient cycling and control of bacterial populations are not well-understood. Enrichment cultures provide models to unravel the role of protists in natural microbial communities. In this project, an uncultivatd ciliate protist related to Platyophyra was enriched by cultivation of a microbial community derived from compost on microcrystalline cellulose at 37 C. Single cell sequencing of this protist will help define its role in the cellulolytic microbial consortia and provide methods to capture the diversity of protists in natural systems.
