Deep-sea Bacteroidetes from the Mariana Trench specialize in hemicellulose and pectin degradation typically associated with terrestrial systems by Xiao-Yu Zhu, Yang Li, Chun-Xu Xue, Ian D. E. A. Lidbury, Jonathan D. Todd, David J. Lea-Smith, Jiwei Tian, Xiao-Hua Zhang, Jiwen Liu

“…Results Here, culture-dependent and culture-independent methods were used to study the potential of Bacteroidetes to catabolize diverse polysaccharides in Mariana Trench waters. Compared to surface waters, the bathypelagic (1000–4000 m) and hadal (6000–10,500 m) waters harbored distinct Bacteroidetes communities, with Mesoflavibacter being enriched at ≥ 4000 m and Bacteroides and Provotella being enriched at 10,400–10,500 m. …”

A moderately thermophilic origin of a novel family of marine group II euryarchaeota from deep ocean by Haodong Liu, Wei-Wei Liu, Jose M. Haro-Moreno, Bu Xu, Yanfen Zheng, Jiwen Liu, Jiwei Tian, Xiao-Hua Zhang, Ning-Yi Zhou, Liping Qin, Yuanqing Zhu, Francisco Rodriguez-Valera, Chuanlun Zhang

“…In this study, 13 new MGII metagenome-assembled genomes were recovered from surface to the hadal zone in Challenger Deep of the Mariana Trench; four of them from the deep ocean represent a novel group. …”
