  1. 1. Galactoglucomannan-degrading enzymes from Aspergillus niger

    Författare :Pia Ademark; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beta-mannanase; Aspergillus niger; beta-mannosidase; alpha-galactosidase; purification; hydrolysis; cloning; galactoglucomannan; expression; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : Galactoglucomannan and galactomannan are among the most abundant plant polysaccharides in nature. The central enzymes involved in their degradation, i.e., endo-1,4-beta-mannanase (beta-mannanase, EC 3. LÄS MER

  3. 2. Systems Biology of Glucose Sensing and Repression in Aspergillus niger: Lessons from Genomics and Transcriptomics

    Författare :Margarita Salazar Pena; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; A. niger; Aspergillus spp.; Transcription Factors; Regulation; Metabolism; Transcriptomics;

    Sammanfattning : Aspergillus comprises a genus of multicellular eukaryotic microorganisms containing close to 200 different species. Among them, the filamentous fungus Aspergillus niger exhibits great diversity in its phenotype and it is found, both in marine and terrestrial habitats. A. niger produces many metabolites that are valuable commodities, e. LÄS MER

  4. 3. Trehalose metabolism and stress resistance in Aspergillus niger

    Författare :Åsa Svanström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Food spoilage by filamentous fungi, moulds, is a global issue of great significance. Mould growth can cause food losses due to deterioration, and adverse health effects due to toxin production. Conidia, asexual spores, are the main factors of dispersal and infection in most food-relevant moulds. LÄS MER

  5. 4. Extracellular serine proteases as virulence factors in nematophagous fungi: Molecular characterization and functional analysis of the PII protease in Arthrobotrys oligospora

    Författare :Johan Åhman; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Aspergillus niger.; Heterologous expression; Over-expression; Gene-disruption; Transformation system; Serine protease; Biological control; Arthrobotrys oligospora; Fungi; Nematophagous; Biologi;

    Sammanfattning : Nematophagous fungi are parasites of nematodes, thus they have been considered and tested for biological control of parasitic nematodes, but so far with limited success. Due to the fact that the nematode cuticle is composed of proteins it is likely that fungal extracellular proteases are involved in the infection of nematodes. LÄS MER
