Ruminant-Waste Protein Hydrolysates and Their Derivatives as a Bio-Flocculant for Oil Sands Tailing Management.

Reclamation of tailings ponds is a critical issue for the oil industry. After years of consolidation, the slurry in tailings ponds, also known as fluid fine tailings, is mainly comprised of residual bitumen, water, and fine clay particles. To reclaim the lands that these ponds occupy, separation of the solid particles from the liquid phase is necessary to facilitate water removal and recycling.

Reverse transcription lesion-induced DNA amplification: An instrument-free isothermal method to detect RNA.

One challenge in point-of-care (POC) diagnostics is the lack of room-temperature methods for RNA detection based on enzymatic amplification and visualization steps. Here we perform reverse transcription lesion-induced DNA amplification (RT-LIDA), an isothermal amplification method that only requires T4 DNA ligase. RT-LIDA involves the RNA-templated ligation of DNA primers to form complementary DNA (cDNA) followed by toehold-mediated strand displacement of the cDNA and its exponential amplification via our isothermal ligase chain reaction LIDA.
