Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Anaerobic digestion can be an alternative method for treating wastewater from second‐generation biorefineries while simultaneously producing biogas. However, the feasibility of the process and key operational parameters by which wastewater produced in lignocellulosic biorefineries affects reactor performance remain poorly understood.

Methanogens and Methanogenesis in Hypersaline Environments
, 2018 Methanogenesis is controlled by redox potential and permanency of anaerobic conditions; and in hypersaline environments, the high concentration of terminal electron acceptors, particularly sulfate, is an important controlling factor.

Nitrogen Fixation in Methanogens: The Archaeal Perspective
, 2000 The methanogenic Archaea bring a broadened perspective to the field of nitrogen fixation. Biochemical and genetic studies show that nitrogen fixation in Archaea is evolutionarily related to nitrogen fixation in Bacteria and operates by the same ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...

The diversity of hydrogen-producing bacteria and methanogens within an in situ coal seam
Biotechnology for Biofuels, 2018 BackgroundBiogenic and biogenic-thermogenic coalbed methane (CBM) are important energy reserves for unconventional natural gas. Thus, to investigate biogenic gas formation mechanisms, a series of fresh coal samples from several representative areas of ...

Mixed Litter Decomposition Drives Functional Gene Rearrangement in the Microbial Carbon Cycle
Land Degradation &Development, EarlyView.ABSTRACT Understanding how mixed‐species litter decomposition regulates microbial communities and carbon cycling is vital for guiding ecosystem restoration and climate change mitigation, as it is a key process for nutrient cycling and carbon sequestration. A 15‐month field experiment compared single‐species (Pinus sylvestris var.

Movement Disorders, EarlyView.Abstract Gastrointestinal dysfunction is increasingly recognized as a core feature of Parkinson's disease (PD), affecting quality of life, nutrition, medication response, and potentially the earliest stages of pathogenesis. This perspective traces the evolution of the gut from a neglected source of non‐motor symptoms to a central component of ...

Interplanetary frontiers: terraforming from an invasion science perspective
Oikos, EarlyView.The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...
