Chemo-autotrophic biogas purification for methane enrichment: mechanism and kinetics
TL;DR: This gas stream treatment process improves the quality and caloric value of the biogas and increases the methane content through the use of a chemo-autotrophic methanogen, uncoupled methanogenesis techniques and hollow fiber membranes.

Effect of Pseudomonas fluorescens on beef discoloration and oxymyoglobin oxidation in vitro
TL;DR: Overall, studies demonstrated that oxygen consumption concomitant with P. fluorescens growth decreased partial oxygen pressure, which accelerated oxymyoglobin oxidation, which indicated that P. influenza could accelerate beef discoloration.

Comparative behavior of e. coli and s. aureus regarding attachment to and removal from a polymeric surface
TL;DR: Staphylococcus aureus was found to attach more readily on polypropylene fibers with greater resistance to subsequent washing off than Escherichia coli after immersion of the fibers up to 300 s in pure culture suspensions in mineral salts medium.

Surface roughness enhances upward migration of bacteria on polymer fibers above liquid cultures.
TL;DR: The migrations observed are attributed predominantly to wicking of the liquid cultures upward in the axial grooves developed on the surface of the PP by the eruption and peeling of microfibrils from the surface to indicate a tendency to wet the PP.
