Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

Abundance and diversity of nitrogen-removing microorganisms in the UASB-anammox reactor.

open access: yesPLoS ONE, 2019
Anaerobic ammonium oxidation is considered to be the most economical and low-energy biological nitrogen removal process. So far, anammox bacteria have not yet been purified from cultures.

Purple Sulfur Bacteria Dominate Microbial Community in Brazilian Limestone Cave

open access: yesMicroorganisms, 2019
The mineralogical composition of caves makes the environment ideal for inhabitation by microbes. However, the bacterial diversity in the cave ecosystem remains largely unexplored.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Treatments on Polypropylene Macro Synthetic Fibers for Improving Adhesion in Structural Concrete Reinforcement: A Systematic Review

open access: yesJournal of Applied Polymer Science, EarlyView.
Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...

Phylogenetic and functional marker genes to study ammonia-oxidizing microorganisms (AOM) in the environment [PDF]

open access: yes, 2018
The oxidation of ammonia plays a significant role in the transformation of fixed nitrogen in the global nitrogen cycle. Autotrophic ammonia oxidation is known in three groups of microorganisms.

Effect of key design parameters on bacteria community and effluent pollutant concentrations in constructed wetlands using mathematical models [PDF]

open access: yes, 2017
Constructed wetlands are currently recognized as an effective environmental biotechnology for wastewater treatment, but the influence of their design parameters on internal functioning and contaminant removal efficiency is still under discussion. In this

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

open access: yesAnimal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Benthic Ammonia Oxidizers Differ in Community Structure and Biogeochemical Potential Across a Riverine Delta

open access: yesFrontiers in Microbiology, 2015
Nitrogen pollution in coastal zones is a widespread issue, particularly in ecosystems with urban or agricultural watersheds. California’s Sacramento-San Joaquin Delta, at the landward reaches of San Francisco Bay, is highly impacted by both agricultural ...
