Journal ArticleDOI

Production of MLM-Type structured lipids catalyzed by immobilized heterologous rhizopus oryzae lipase

P. A. Nunes, +7 more
- 01 Apr 2011 - 
TL;DR: In this paper, a triacylglycerols (TAG) containing a medium chain fatty acid (M) at positions sn-1,3 and a long-chain fatty acid at sn-2 position was produced by the methylotrophic yeast Pichia pastoris.
Journal ArticleDOI

Biosynthesis of ethyl butyrate by immobilized recombinant Rhizopus oryzae lipase expressed in Pichia pastoris

Marina Guillén, +2 more
- 15 Jun 2012 - 
TL;DR: In this article, a recombinant Rhizopus oryzae lipase expressed in Pichia pastoris has been immobilized in three different kinds of supports: EP100, Eupergit®CM and Octadecyl-Sepabeads.
Journal ArticleDOI

Immobilized heterologous Rhizopus oryzae lipase: A feasible biocatalyst for the production of human milk fat substitutes

Carla Tecelão, +4 more
- 15 Aug 2012 - 
TL;DR: An important increase in the operational stability was observed for rROL immobilized in Lewatit after rehydration at the end of each batch, and the loss of activity may be explained by a progressive dehydration occurring along the reaction.
Journal ArticleDOI

Comparison of the biochemical properties of a recombinant lipase extract from Rhizopus oryzae expressed in Pichia pastoris with a native extract

Marina Guillén, +2 more
- 15 Apr 2011 - 
TL;DR: Extracts containing mature Rhizopus oryzae lipase overexpressed in Pichia pastoris and commercial ones from the native microorganism (nROL) have been characterized as discussed by the authors.
Journal ArticleDOI

Batch operational stability of immobilized heterologous Rhizopus oryzae lipase during acidolysis of virgin olive oil with medium-chain fatty acids

Patrícia A. Nunes, +6 more
- 15 Aug 2012 - 
TL;DR: A first-order deactivation was observed during acidolysis with capric acid catalyzed by r-ROL immobilized in Lewatit VP OC 1600 and with rehydration, a considerable increase in stability was observed.
