TL;DR: Terminal restriction fragment length polymorphism analysis of 16S rRNA genes was used to investigate the reproducibility and stability in the bacterial community structure of laboratory-scale sequencing batch bioreactors and to assess the impact of solids retention time (SRT) on bacterial diversity.

TL;DR: In this paper, the authors employ confocal microscopy for the in situ, three-dimensional study of micron-scale hydrogels that are pinned to a solid substrate and find four general modes of swelling-induced deformation: lateral differential swelling, local sinusoidal edge buckling, bulk sinusoid buckling and surface creasing.

TL;DR: The potential use of the hydrogel monoliths as size-selective "catch and release" structures was demonstrated with a mixture of 6 and 20 microm polystyrene microspheres, where the 6 microm diameter particles were selectively concentrated and separated from the larger particles.

TL;DR: Two fractions of mucilage gum were extracted from the Opuntia ficus-indica cactus and tested as flocculation agents against sediment and bacterial contamination and showed water purification abilities.

TL;DR: Green fluorescent protein (GFP) transformed E. coli O157:H7 was used to develop a novel method for directly and easily measuring the cell capture efficiency of any given biosensor platform, and can facilitate the development and optimization of new biosensor design configurations and sample processing strategies.
