Assessment of the diversity, abundance, and ecological distribution of members of candidate division SR1 reveals a high level of phylogenetic diversity but limited morphotypic diversity
Davis, James P.; Youssef, Noha H.; Elshahed, Mostafa S. (American Society for Microbiology, 2009-06)We used a combination of 16S rRNA gene clone library surveys, quantitative PCR (qPCR) analysis, and fluorescent in situ hybridization to investigate the diversity, abundance, and distribution of members of candidate division ... -
Genome of the anaerobic fungus Orpinomyces sp. strain C1A reveals the unique evolutionary history of a remarkable plant biomass degrader
Youssef, Noha H.; Couger, M. B.; Struchtemeyer, Christopher G.; Liggenstoffer, Audra S.; Prade, Rolf A.; Najar, Fares Z.; Atiyeh, Hasan K.; Wilkins, Mark R.; Elshahed, Mostafa S. (American Society for Microbiology, 2013-08)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, ... -
Novelty and uniqueness patterns of rare members of the soil biosphere
Elshahed, Mostafa S.; Youssef, Noha H.; Spain, Anne M.; Sheik, Cody; Najar, Fares Z.; Sukharnikov, Leonid O.; Roe, Bruce A.; Davis, James P.; Schloss, Patrick D.; Bailey, Vanessa L.; Krumholz, Lee R. (American Society for Microbiology, 2008-09)Soil bacterial communities typically exhibit a distribution pattern in which most bacterial species are present in low abundance. Due to the relatively small size of most culture-independent sequencing surveys, a detailed ... -
Partial genome assembly for a candidate division OP11 single cell from an anoxic spring (Zodletone Spring, Oklahoma)
Youssef, Noha H.; Blainey, Paul C.; Quake, Stephen R.; Elshahed, Mostafa S. (American Society for Microbiology, 2011-11)Members of candidate division OP11 are widely distributed in terrestrial and marine ecosystems, yet little information regarding their metabolic capabilities and ecological role within such habitats is currently available. ... -
Patterns and determinants of halophilic Archaea (class Halobacteria) diversity in Tunisian endorheic salt lakes and sebkhet systems
Najjari, Afef; Elshahed, Mostafa S.; Cherif, Ameur; Youssef, Noha H. (American Society for Microbiology, 2015-07)We examined the diversity and community structure of members of the halophilic Archaea (class Halobacteria) in samples from central and southern Tunisian endorheic salt lakes and sebkhet (also known as sebkha) systems using ... -
Phylogenetic and metabolic diversity of Planctomycetes from anaerobic, sulfide- and sulfur-rich Zodletone Spring, Oklahoma
Elshahed, Mostafa S.; Youssef, Noha H.; Luo, Qingwei; Najar, Fares Z.; Roe, Bruce A.; Sisk, Tracy M.; Buhring, Solveig I.; Hinrichs, Kai-Uwe; Krumholz, Lee R. (American Society for Microbiology, 2007-08)We investigated the phylogenetic diversity and metabolic capabilities of members of the phylum Planctomycetes in the anaerobic, sulfide-saturated sediments of a mesophilic spring (Zodletone Spring) in southwestern Oklahoma. ... -
Phylogenetic diversities and community structure of members of the extremely halophilic Archaea (order Halobacteriales) in multiple saline sediment habitats
Youssef, Noha H.; Ashlock-Savage, Kristen N.; Elshahed, Mostafa S. (American Society for Microbiology, 2012-03)We investigated the phylogenetic diversity and community structure of members of the halophilic Archaea (order Halobacteriales) in five distinct sediment habitats that experience various levels of salinity and salinity ... -
Transcriptomic analysis of lignocellulosic biomass degradation by the anaerobic fungal isolate Orpinomyces sp. strain C1A
Couger, M. B.; Youssef, Noha H.; Struchtemeyer, Christopher G.; Liggenstoffer, Audra S.; Elshahed, Mostafa S. (BioMed Central, 2015-12-08)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 ... -
Utilizing anaerobic fungi for two-stage sugar extraction and biofuel production from lignocellulosic biomass
Ranganathan, Abhaya; Smith, Olivia P.; Youssef, Noha H.; Struchtemeyer, Christopher G.; Atiyeh, Hasan K.; Elshahed, Mostafa S. (Frontiers Media, 2017-04-11)Lignocellulosic biomass is a vast and underutilized resource for the production of sugars and biofuels. However, the structural complexity of lignocellulosic biomass and the need for multiple pretreatment and enzymatic ...
