Combined Effect of Cetane Improver, Aluminum Oxide Nanoparticles, and Waste Cooking Oil Biodiesel Blend on a Dual Fuel Combustion Engine Run With Biogas Originated From Food Waste

Energy Science &Engineering, EarlyView.
Sugarcane juice is clarified and fermented with yeast to produce ethanol and CO₂. The broth is refined through distillation and molecular sieves, yielding fuel‐grade ethanol stored for transport. Bagasse, vinasse, and residues are recycled as valuable by‐products, enabling a sustainable bioethanol production pathway ABSTRACT This study investigates the

Anaerobic methanotrophic communities thrive in deep submarine permafrost

Scientific Reports, 2018
Thawing submarine permafrost is a source of methane to the subsurface biosphere. Methane oxidation in submarine permafrost sediments has been proposed, but the responsible microorganisms remain uncharacterized.

Current Advancements of Probiotic Foods and Their Role in Sustainable Food Security

Food Bioengineering, EarlyView.
ABSTRACT Probiotic foods have evolved from traditional fermented products to scientifically validated functional foods, defined by the FAO and WHO as live microorganism that confer a health benefit on the host when administered in adequate amounts, with effects being strain, does and end point specific.

Methane‐Driven Arsenic Biogeochemical Cycling in Deep‐Sea Cold Seeps: Implications for Oceanic Arsenic Geochemistry

Geophysical Research Letters
Arsenic accumulation in seafloor cold seeps is poorly understood. Here, we investigate the interplay between arsenic and methane biogeochemical cycles at the Haima cold seep, South China Sea.

Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]

, 2016
Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...

Relating Methanogen Community Structure and Anaerobic Digester Function [PDF]

, 2015
Much remains unknown about the relationships between microbial community structure and anaerobic digester function. However, knowledge of links between community structure and function, such as specific methanogenic activity (SMA) and COD removal rate ...

Reverse methanogenesis and respiration in methanotrophic archaea [PDF]

, 2017
Anaerobic oxidation of methane (AOM) is catalyzed by anaerobic methane-oxidizing archaea (ANME) via a reverse and modified methanogenesis pathway. Methanogens can also reverse the methanogenesis pathway to oxidize methane, but only during net methane ...

The role of the gut microbiome in the regulation of high‐altitude adaptation

iMeta, EarlyView.
This study is the first to elucidate mechanisms of high‐altitude adaptation from the perspective of the rumen ecosystem by using indigenous yaks and Holstein cows that have lived at high altitude since birth as comparative models. Through a systematic comparison of their rumen ecology using multi‐omics approaches—including rumen metagenomics ...
