Anaerobic gut fungi represent a distinct early-branching fungal phylum (Neocallimastigomycota) and reside in the rumen, hindgut, and feces of ruminant and nonruminant herbivores. The genome of an anaerobic fungal isolate, Orpinomyces sp. strain C1A, was sequenced using a combination of Illumina and PacBio single-molecule real-time (SMRT) technologies. The(More)
Members of the anaerobic fungi (Phylum Neocallimastigomycota) are efficient biomass degraders and represent promising agents for fuel and chemical production from lignocellulosic biomass. Pretreatment of lignocellulosic biomass is considered an unavoidable first step in enzyme-based saccharification schemes, but its necessity in any proposed anaerobic(More)
The phylogenetic diversity and community structure of members of the gut anaerobic fungi (AF) (phylum Neocallimastigomycota) were investigated in 30 different herbivore species that belong to 10 different mammalian and reptilian families using the internal transcribed spacer region-1 (ITS-1) ribosomal RNA (rRNA) region as a phylogenetic marker. A total of(More)
This contribution is based on the six oral presentations given at the Special Interest Group session on anaerobic fungi held during IMC9. These fungi, recently elevated to the status of a separate phylum (Neocallimastigomycota), distinct from the chytrid fungi, possess several unique traits that make their study both fascinating yet challenging to(More)
An aerobic bacterium, Ralstonia sp. strain TRW-1, that assimilates vinyl chloride (VC) or ethene (ETH) as the sole carbon source was isolated from a chloroethene-degrading enrichment culture. Phylogenetic analysis of 16S rDNA sequence of the isolate revealed almost 99% sequence similarity to Ralstonia pickettii. To our knowledge, this is the first report(More)
BACKGROUND Anaerobic fungi reside in the rumen and alimentary tract of herbivores where they play an important role in the digestion of ingested plant biomass. The anaerobic fungal isolate Orpinomyces sp. strain C1A is an efficient biomass degrader, capable of simultaneous saccharification and fermentation of the cellulosic and hemicellulosic fractions in(More)
Anaerobic fungi are efficient plant biomass degraders and represent promising agents for a variety of biotechnological applications. We evaluated the tolerance of an anaerobic fungal isolate, Orpinomyces sp. strain C1A, to air exposure in liquid media using soluble (cellobiose) and insoluble (dried switchgrass) substrates. Strain C1A grown on cellobiose(More)
The anaerobic gut fungi (AGF) inhabit the rumen and alimentary tracts of multiple ruminant and nonruminant herbivores, belong to a distinct phylum-level lineage (Neocallimastigomycota), and play an important role in plant biomass degradation in many herbivores. As part of a wider effort to obtain AGF with high lignocellulolytic capacities, we isolated and(More)
