Diversity of cultivable fungi associated with Antarctic marine sponges and screening for their antimicrobial, antitumoral and antioxidant potential
The diversity of sponge-associated fungi has been poorly investigated in remote geographical areas like Antarctica. In this study, 101 phenotypically different fungal isolates were obtained from 11Expand

Differences in expression of two endoxylanase genes (xynA and xynB) from Penicillium purpurogenum.
A number of xylanolytic microorganisms secrete to the medium several molecular forms of endoxylanases. The physiological function of these isoforms is not clear; one possibility is that they areExpand

Electrophoretic karyotype of the filamentous fungus Penicillium purpurogenum and chromosomal location of several xylanolytic genes.
The electrophoretic karyotype of the filamentous fungus Penicillium purpurogenum has been resolved. Using contour-clamped homogeneous electric field gel electrophoresis, five chromosomal bands wereExpand

Cultivable psychrotolerant yeasts associated with Antarctic marine sponges
Unlike filamentous fungi and bacteria, very little is known about cultivable yeasts associated with marine sponges, especially those from Antarctic seas. During an expedition to King George Island,Expand

Structure analysis of the endoxylanase A gene from penicillium purpurogenum.
Penicillium purpurogenum produces several endoxylanases, two of which (XynA and XynB) have been purified and characterized. XynB has been sequenced, and it belongs to glycosyl hydrolase family 11. InExpand

Cold-Active Xylanase Produced by Fungi Associated with Antarctic Marine Sponges
Despite their potential biotechnological applications, cold-active xylanolytic enzymes have been poorly studied. In this work, 38 fungi isolated from marine sponges collected in King George Island,Expand

Molecular characterization of the niaD and pyrG genes from Penicillium camemberti, and their use as transformation markers
Genetic manipulation of the filamentous fungus Penicillium camemberti has been limited by a lack of suitable genetics tools for this fungus. In particular, there is no available homologousExpand

Detection of arsenic-binding siderophores in arsenic-tolerating Actinobacteria by a modified CAS assay.
The metalloid arsenic is highly toxic to all forms of life, and in many countries decontamination of water and soil is still required. Some bacteria have mechanisms to detoxify arsenic and can liveExpand

Penicillium purpurogenum produces a family 1 acetyl xylan esterase containing a carbohydrate-binding module: characterization of the protein and its gene.
At least three acetyl xylan esterases (AXE I, II and III) are secreted by Penicillium purpurogenum. This publication describes more detailed work on AXE I and its gene. AXE I binds cellulose but notExpand

A preparative method for the purification of isopenicillin N from genetically blocked Acremonium chrysogenum strain TD189: studies on the degradation kinetics and storage conditions
A protocol for preparative isopenicillin N (IPN) purification, a highly interesting and hitherto unavailable intermediate of the penicillin and cephalosporin biosynthetic pathway due to its highExpand
