The production of xylanase (XylA) by Aspergillus niger JL-15 in solid-state fermentation (SSF) on orange peel was optimised by the response surface methodology (RSM). The results revealed that four fa...
An extracellular endoinulinase P-III from Aspergillus niger 12 has been immobilized covalently onto bromoacetyl-cellulose (BAC), cellulose-carbonate (CC) and CNBr-activated Sepharose 4B (CAS) with the...
Endoinulinase was partially purified from the culture filtrate of a filamentous fungus Aspergillus niger mutant 817. The enzyme preparation was immobilized covalently onto a porous cellulose derivativ...
Transfructosylation catalyzed by fructooligosaccharide-producing b-fructofuranosidase from Aspergillus niger ATCC 20611 was kinetically studied and a reaction model of transfructosylation was proposed...
Fungal mycelium pellets of Aspergillus niger 405 were used for adsorption of different metal ions. The biosorption of Cu2+, Zn2+, Ni2+ and CrO42- was studied over a range of metal ion concentrations, ...
Qualitative relationships between agitation levels and medium viscosity, Aspergillus niger morphology and phytase production were investigated in submerged and solid-state fermentations. Overall phyta...
The characteristics of growth, productivity and morphology varied with the mixing system and the applied agitation regime. In the first series of experiments, the flow characteristics of Aspergillus n...
With the results presented we would like to emphasize the influence of dissolved oxygen concentration in a medium on intracellular pH values and consequently on overall metabolism of microorganisms. I...
The aim of the present study was to investigate a new approach to beta-glucosidase production of an Aspergillus strain using cheap lignocellulosic material i.e. waste paper in order to substitute gluc...
The most common expression strategy for secreting heterologous proteins from filamentous fungus Aspergillus niger is based on fusion with glucoamylase gene which contains cleavage site for kexin prote...
The production of citric acid from fermentation medium (mass per volume ratio 0.01 % of undersized semolina) by Aspergillus niger was studied by shake culture method. The effects of initial pH (4.5, 5...
The simplex method has been used to optimise the inulinase production by Aspergillus niger strain 13/36 with respect to 5 components of the medium. The extracellular enzyme activity was almost 80 U/mL...
Tannin acyl hydrolase produced extracellularly by the fungal strain Aspergillus niger ATTC 16620 in solid state fermentation was purified from the cell free culture broth by ammonium sulphate fraction...
The influence of carbon sources, nitrogen sources, and the addition of sucrose ester on fructanohydrolase production was investigated. The enzyme production varied depending on the carbon source. Apar...
Extracellular inulinase (E.C. 3.2.1.7) produced by Aspergillus niger 20 OSM culture in a 2-litre fermentor was isolated and purified by ion exchange chromatography on DEAE Sepharose, hydrophobic inter...
