Solid-state fermentation as a potential technique for esterase/lipase production by halophilic archaea.

Extremophiles 19 , 1121-32, (2015)

Halophilic archaea are extremophiles, adapted to high-salt environments, showing a big biotechnological potential as enzyme, lipids and pigments producers. Four inert supports (perlite, vermiculite, p...

Enhanced productivity of electrospun polyvinyl alcohol nanofibrous mats using aqueousN,N-dimethylformamide solution and their application to lipase-immobilizing membrane-shaped catalysts

J. Biosci. Bioeng. 114(2) , 204-8, (2012)

Electrospun polyvinyl alcohol (PVA) nanofibrous non-woven fabrics have been widely used for cell and enzyme immobilization. Enhancement of the productivity of the material will further enlarge the ver...

Lipase-catalysed hydrolysis of short-chain substrates in solution and in emulsion: a kinetic study.

Biochim. Biophys. Acta 1534(1) , 34-44, (2001)

We have studied the enzymatic hydrolysis of solutions and emulsions of vinyl propionate, vinyl butyrate and tripropionin by lipases of various origin and specificity. Kinetic studies of the hydrolysis...
