Foam flotation has been recently investigated for the recovery of microalgae cells from dilute liquid suspensions. A number of variables on the effectiveness of foam flotation for microalgae have been investigated, which include surfactant type and concentration, cell concentration, pH, hydrophobicity, time, growth stage, flow rate, ionic

Flotation of nuclei appeared to depend on the low salt concentration used in the bottom of the gradient. We hypothesize that under these conditions, chromatin may at least partially decondense , ...

Apr 05, 2002 Using cell fractionation and equilibrium flotation techniques we discovered that substantial amounts of inactive and activated STATs existed in detergent-resistant plasma membrane rafts derived from human hepatoma Hep3B cells. In these membranes, STATs co-rafted with the integral raft proteins caveolin-1 and flotillin-1, with cytokine receptor

Although biochemical analysis requires disruption of the anatomy of the cell, gentle fractionation techniques have been devised to separate the various cell components while preserving their individual functions. Just as a tissue can be separated into its living constituent cell types, so the cell can be separated into its functioning organelles and macromolecules

mal cells, followed by the fractionation of the non-parenchymal cells. Stellate cells are the least dense of the different cell types in both tissues and they can be purified either by sedimentation on to, or flotation through, a suitable density barrier. Both strategies have been used effec-tively but flotation is often regarded as superior to

Jul 01, 2015 High-turbulence flotation cells was used for plastics flotation in certain cases (Sisson, 1993, Hwang, 1995, Kobler, 1995). In most of these applications, the separation was carried out on flake-shaped particles less than about 12 mm in size having a thickness less than 0.75 mm

Cell fractionation involves 3 steps: Extraction, Homogenization and Centrifugation. 1. Extraction: It is the first step toward isolating any sub-cellular structures. In order to maintain the biological activity of organelles and bio-molecules, they must be extracted in mild conditions called cell-free systems

15.3 Foam fractionation. Foam fractionation, also called protein skimming, air stripping and froth flotation, removes surface active (surfactants) dissolved organics and suspended solids, which may be produced in the culture system. If aeration is vigorous, the process can also drive ammonia and volatile components directly to the atmosphere
