Diversity of pili-specific bacteriophages: genome sequence of IncM plasmid-dependent RNA phage M

BMC Microbiology, 2012
Background Bacteriophages of the Leviviridae family are small RNA viruses with linear, positive-sense, single-stranded RNA genomes that encode only four proteins. All phages of this family require bacterial pili to attach to and infect cells. Leviviridae

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

Asia-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 ...

Effect of Binder on Physical Properties of Extruded Activated Carbon and Its Application to Levofloxacin Adsorption

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Bamboo charcoal–based extruded activated carbons were prepared via molding, pre‐oxidation, carbonization, and steam activation, with coal tar, phenolic resin, and their mixtures employed as binders based on practical availability and technical feasibility. This study focused on the regulatory effects of binders on the mechanical properties and
