New aqueous two-phase system based on cashew-nut tree gum and poly(ethylene glycol)

Liquid–liquid extraction of biomolecules: an overview and update of the main techniques

“…Although the salts distribute almost evenly between the phases, there are small, but significant, differences in the coefficients of partition of ions, creating a difference in electric potential between the phases, which can direct the loaded biological molecule partition. 95,98 Accordingly, a significant electrostatic potential difference can exist depending on the salt used to govern electroneutrality.…”

Practical application of aqueous two-phase partition to process development for the recovery of biological products

“…Furthermore, the use of ucon favours the potential recycling of the chemicals forming phases by altering the process temperature. In the search for alternative low cost chemical forming phases for ATPS, the use of novel or exotic compounds such as cashew nut tree gum has been reported [33]. The great disadvantage of this latest type of ATPS is associated with the need of a formal and complete characterisation of the ATPS (i.e.…”

“…construction of the phase diagram, partition behaviour of commercial proteins in the systems, etc.). In addition, low process efficiency is a common characteristic of these ATPS as compared with that from commercial or traditional ATPS [33]. Such a situation can be explained by the low purification of the compounds used to form the phases and the resulting effect on the product partition behaviour.…”

Morphology and water affinity of superabsorbent hydrogels composed of methacrylated cashew gum and acrylamide with good mechanical properties

“…Cashew gum is a low cost polysaccharide extracted from the cashew tree Anacardium occidentale [16][17][18] [19,20]. This polysaccharide is composed of arabinose, glucose, glucuronic acid, galactose, mannose and rhamnose [21,22] and it is designed as branched acidic hetero-polysaccharide of complex structure. The majority of papers have been addressed to polysaccharide-based hydrogels of lesser complex structure.…”
