Comparison of different types of pretreatment and enzymatic saccharification of Macrocystis pyrifera for the production of biofuel
In this work, the brown algae Macrocystis pyrifera were pretreated with dilute sulfuric acid, water and three different types of ionic liquids (ILs): 1-ethyl-3-methylimidazolium acetate ([EMIM][OAcExpand
Adrenal rest tumor of the liver causing Cushing's syndrome: treatment with ketoconazole preceding an apparent surgical cure.
It is concluded that ketoconazole was effective in blocking tumoral steroidogenesis which resulted in clinical benefit and the patient is apparently cured as judged by steroid hormone levels and physical appearance. Expand
Novel Bifunctional α-l-Arabinofuranosidase/Xylobiohydrolase (ABF3) from Penicillium purpurogenum
ABF3 is the first described modular family 43 enzyme from a fungal source, having both α-l-arabinofuranosidase and xylobiohydrolase functionalities. Expand
A family 51 alpha-l-arabinofuranosidase from Penicillium purpurogenum: purification, properties and amino acid sequence.
Results suggest that arabinofuranosidase 2 belongs to the exo alpha-l-arabinosyl hydrolases not active on polymers, although it differs in some properties from other enzymes of this family. Expand
Cold-Active Xylanase Produced by Fungi Associated with Antarctic Marine Sponges
This study is the first report on extracellular xylanase production by fungi associated with Antarctic marine sponges, and one of these isolates, Cladosporium sp. Expand
Penicillium purpurogenum produces a family 1 acetyl xylan esterase containing a carbohydrate-binding module: characterization of the protein and its gene.
It is proposed that AXe I and II act in succession in xylan degradation; first, xylan is attacked by AXE I and other xylanases possessing CBMs (which facilitate binding to lignocellulose), followed by other enzymes acting mainly on soluble substrates. Expand
The role of alginate lyases in the enzymatic saccharification of brown macroalgae, Macrocystis pyrifera and Saccharina latissima
It was shown that brown algae hydrolysates could be used as a growth medium to produce microbial ingredients, such as Candida utilis yeast, and only cellulases were needed to achieve high glucose yields. Expand
Heterologous expression, purification and characterization of a highly thermolabile endoxylanase from the Antarctic fungus Cladosporium sp.
This work cloned a cDNA from the Antarctic fungus Cladosporium sp. Expand
Heterologous expression and biochemical characterization of a novel cold-active α-amylase from the Antarctic bacteria Pseudoalteromonas sp. 2-3.
α-Amylase is an endo-acting enzyme which catalyzes random hydrolysis of starch. These enzymes are used in various biotechnological processes including the textile, paper, food, biofuels, detergentsExpand
Penicillium purpurogenum produces two GH family 43 enzymes with β-xylosidase activity, one monofunctional and the other bifunctional: Biochemical and structural analyses explain the difference.
The structural analysis shows that active complexes possess specific interactions between substrates and catalytic residues, which are absent in the inactive complex (XYL1-pNPAra), while other interactions with non-catalytic residues are found in all complexes. Expand
