Metagenome of a polluted river reveals a reservoir of metabolic and antibiotic resistance genes - 2019
Parul Mittal, Vishnu Prasoodanan Pk, Darshan B. Dhakan, Sanjiv Kumar, Vineet K. Sharma
Abstract
Background
Yamuna, a major tributary of Ganga, which flows through the national capital region of Delhi, is among the major polluted rivers in India. The accumulation of various effluents, toxic chemicals, heavy metals, and increased organic load in the Yamuna directly affect...... hiện toàn bộ
Estuarine gradients dictate spatiotemporal variations of microbiome networks in the Chesapeake Bay Tập 16 Số 1 - 2021
Hualong Wang, Feng Chen, Chuanlun Zhang, Min Wang, Jinjun Kan
Abstract
Background
Annually reoccurring microbial populations with strong spatial and temporal variations have been identified in estuarine environments, especially in those with long residence time such as the Chesapeake Bay (CB). However, it is unclear how microbial taxa cooccurr and how the inte...... hiện toàn bộ
Seasonal dynamics in taxonomy and function within bacterial and viral metagenomic assemblages recovered from a freshwater agricultural pond Tập 15 Số 1 - 2020
Jessica Chopyk, Daniel J. Nasko, Sarah Allard, Anthony Bui, Mihai Pop, Emmanuel F. Mongodin, Amy R. Sapkota
AbstractBackgroundPonds are important freshwater habitats that support both human and environmental activities. However, relative to their larger counterparts (e.g. rivers, lakes), ponds are understudied, especially with regard to their microbial communities. Our study aimed to fill this knowledge gap by using culture-independent,...... hiện toàn bộ
A rather dry subject; investigating the study of arid-associated microbial communities - 2020
Peter Osborne, Lindsay J. Hall, Noga Kronfeld‐Schor, David Thybert, Wilfried Haerty
AbstractAlmost one third of Earth’s land surface is arid, with deserts alone covering more than 46 million square kilometres. Nearly 2.1 billion people inhabit deserts or drylands and these regions are also home to a great diversity of plant and animal species including many that are unique to them. Aridity is a multifaceted environmental stress combining a lack of...... hiện toàn bộ
Rhizosheath–root system changes exopolysaccharide content but stabilizes bacterial community across contrasting seasons in a desert environment Tập 17 Số 1 - 2022
Ramona Marasco, Marco Fusi, María J. Mosqueira, Jenny Marie Booth, Federico Rossi, Massimiliano Cardinale, Grégoire Michoud, Eleonora Rolli, Gianmarco Mugnai, Lorenzo Vergani, Sara Borin, Roberto De Philippis, Ameur Chérif, Daniele Daffonchio
Abstract
Background
In hot deserts daily/seasonal fluctuations pose great challenges to the resident organisms. However, these extreme ecosystems host unique microenvironments, such as the rhizosheath–root system of desert speargrasses in which biological activities and interactions are facilitated ...... hiện toàn bộ
Nutrient-limited subarctic caves harbour more diverse and complex bacterial communities than their surface soil
Ana Sofia P. S. Reboleira, Kasun H. Bodawatta, Nynne M. R. Ravn, Stein‐Erik Lauritzen, Rannveig Øvrevik Skoglund, Michael Poulsen, Anders Michelsen, Knud A. Jønsson
Abstract
Background
Subarctic regions are particularly vulnerable to climate change, yet little is known about nutrient availability and biodiversity of their cave ecosystems. Such knowledge is crucial for predicting the vulnerability of these ecosystems to consequences of climate change. Thus, to i...... hiện toàn bộ
Natural selenium stress influences the changes of antibiotic resistome in seleniferous forest soils Tập 17 Số 1 - 2022
Fangfang Wang, Guoping Liu, Fan Zhang, Zong-Ming Li, Xiaolin Yang, Chaodong Yang, Jianlin Shen, Ji‐Zheng He, B Larry Li, Jianguo Zeng
AbstractBackgroundMetal(loid)s can promote the spread and enrichment of antibiotic resistance genes (ARGs) in the environment through a co-selection effect. However, it remains unclear whether exposure of microorganisms to varying concentrations of selenium (Se), an essential but potentially deleterious metal(loid) to living organ...... hiện toàn bộ
