1359-5113
Subject:
air drying; emulsions; encapsulation; evaporation; hydrophobicity; immobilized cells; metabolites; solvents
Abstract:
... Immobilization of microbial cells in hydrophobic resin capsules for various bioprocesses such as metabolite production allows for greater efficiency than use of free cells. Conventional emulsion solvent evaporation (ESE) technique can seriously damage microbial cells in capsules by organic solvents. To overcome this issue, we applied an air drying technique on superamphiphobic surfaces for encapsu ...

Abstract:
... Studies with extractive fermentation using non-ionic surfactant L62 have relieved butanol toxicity and enhanced butanol production. Subsequently, L62 was used for extraction of butanol from a fermentation system using cloud point extraction (CPE). However, the back-extraction of butanol and recovery of surfactant from coacervate phase and reuse of surfactant remains a major challenge. This work pr ...
