Aspergillus vadensis, a new species of the group of black AspergilliRonald P de Vries
Molecular Genetics of Industrial Microorganisms, Wageningen University, Dreijenlaan 2, 6703 HA, Wageningen, The Netherlands
Antonie Van Leeuwenhoek 87:195-203. 2005..These data indicate that the strain was closely related but not identical to Aspergillus foetidus, Aspergillus niger and Aspergillus tubingensis. It was therefore designated as a novel species and named Aspergillus vadensis...- A new black Aspergillus species, A. vadensis, is a promising host for homologous and heterologous protein productionRonald P de Vries
Molecular Genetics of Industrial Microorganisms, Wageningen University, The Netherlands
Appl Environ Microbiol 70:3954-9. 2004..vadensis were much higher than those of A. niger. These characteristics make A. vadensis a very promising candidate for homologous, and possibly heterologous, protein production... - Glycerol dehydrogenase, encoded by gldB is essential for osmotolerance in Aspergillus nidulansRonald P de Vries
Molecular Genetics of Industrial Microorganisms, Wageningen University, Dreijenlaan 2, 6703 HA Wageningen, The Netherlands
Mol Microbiol 49:131-41. 2003..These data indicate that gldB is essential for osmotolerance in A. nidulans and that the pathways for glycerol biosynthesis under osmotic stress differ between yeast and filamentous fungi... - Regulation of Aspergillus genes encoding plant cell wall polysaccharide-degrading enzymes; relevance for industrial productionR P de Vries
Microbiology, Utrecht University, Padualaan 8, 3584 CH Utrecht, The Netherlands
Appl Microbiol Biotechnol 61:10-20. 2003..The latter is of major importance in the large-scale production of these enzymes for industrial applications... - Expression profiling of pectinolytic genes from Aspergillus nigerRonald P de Vries
Molecular Genetics of Industrial Microorganisms, Wageningen University, The Netherlands
FEBS Lett 530:41-7. 2002..In addition, subsets of pectinolytic genes are expressed in response to the presence of L-arabinose, L-rhamnose or ferulic acid... - The beta-1,4-endogalactanase A gene from Aspergillus niger is specifically induced on arabinose and galacturonic acid and plays an important role in the degradation of pectic hairy regionsRonald P de Vries
Molecular Genetics of Industrial Microorganisms and Food Chemistry, Wageningen University, Wageningen, The Netherlands
Eur J Biochem 269:4985-93. 2002..This is the first report of the ability of a beta-1,4-endogalactanase to release substituted d-galacto-oligosaccharides. GALA was not active towards d-galacto-oligosaccharides that were substituted with d-glucose at the reducing end... - Regulation of the alpha-glucuronidase-encoding gene ( aguA) from Aspergillus nigerR P de Vries
Department of Microbiology, Utrecht University, Padualaan 8, 3508 TB Utrecht, The Netherlands
Mol Genet Genomics 268:96-102. 2002..This system responds to the presence of glucuronic and galacturonic acids, and is not dependent on XLNR... - The Aspergillus niger faeB gene encodes a second feruloyl esterase involved in pectin and xylan degradation and is specifically induced in the presence of aromatic compoundsRonald P de Vries
Molecular Genetics of Industrial Microorganisms, Wageningen University, Dreijenlaan 2, 6703 HA Wageningen, The Netherlands
Biochem J 363:377-86. 2002..FAEA is more active than FAEB towards wheat arabinoxylan, whereas FAEB is more active than FAEA towards sugar-beet pectin... - CreA modulates the XlnR-induced expression on xylose of Aspergillus niger genes involved in xylan degradationR P de Vries
Molecular Genetics of Industrial Microorganisms, Wageningen Agricultural University, The Netherlands
Res Microbiol 150:281-5. 1999..The genes tested were not influenced to the same extent by XlnR or CreA, resulting in specific expression levels and patterns for each individual gene... - The Aspergillus niger D-xylulose kinase gene is co-expressed with genes encoding arabinan degrading enzymes, and is essential for growth on D-xylose and L-arabinoseP A vanKuyk
Molecular Genetics of Industrial Microorganisms, Wageningen University, Dreijenlaan 2, Wageningen, The Netherlands
Eur J Biochem 268:5414-23. 2001.... - Aspergillus enzymes involved in degradation of plant cell wall polysaccharidesR P de Vries
Molecular Genetics of Industrial Microorganisms, Wageningen University, 6703 HA Wageningen, The Netherlands
Microbiol Mol Biol Rev 65:497-522, table of contents. 2001..This review summarizes our current knowledge of the cell wall polysaccharide-degrading enzymes from aspergilli and the genes by which they are encoded... - Cloning and characterization of Aspergillus niger genes encoding an alpha-galactosidase and a beta-mannosidase involved in galactomannan degradationP Ademark
Department of Biochemistry, Center for Chemistry and Chemical Engineering, Lund University, Sweden
Eur J Biochem 268:2982-90. 2001..niger, and the combined action of these enzymes degraded a galactomanno-oligosaccharide into galactose and mannose. The possible roles of AglC and MndA in galactomannan hydrolysis is discussed... - The faeA genes from Aspergillus niger and Aspergillus tubingensis encode ferulic acid esterases involved in degradation of complex cell wall polysaccharidesR P de Vries
Wageningen Agricultural University, The Netherlands
Appl Environ Microbiol 63:4638-44. 1997..The rate of release was enhanced by the presence of a xylanase. FAEA also hydrolyzed smaller amounts of ferulic acid from sugar beet pectin, but the rate was hardly affected by addition of an endo-pectin lyase...
