Optimization of biomass, pellet size and polygalacturonase production by Aspergillus sojae ATCC 20235 using response surface methodology
TL;DR: A two-step optimization procedure using central composite design with four factors (concentrations of maltrin and corn steep liquor, agitation speed and inoculation ratio) was used to investigate the effect of these parameters on the polygalacturonase (PG) enzyme activity, mycelia growth (biomass) and morphology (pellet size) of Aspergillus sojae ATCC 20235.

Enzymatic hydrolysis of carrot for extraction of a cloud-stable juice
TL;DR: In this paper, the influence of various enzymes on the cell wall structure of carrots (Daucus carrota) was examined and related to changes in the juice extracted from the pulp with respect to volume, solids content, pH and viscosity.

Statistical optimization of medium components for improved synthesis of pectinase by Aspergillus niger
S. R. Nair,Tapobrata Panda +1 more
TL;DR: In this article, the synthesis of pectinase using Aspergillus niger, NCIM 548, has been enhanced by optimizing the carbon and nitrogen sources present in the medium.

Production of pectolytic enzymes by Aspergillus niger: effect of inoculum size and potassium hexacyanoferrate II-trihydrate
TL;DR: A pronounced effect of KHCF on fungal morphology as well as on enzymatic activity was observed, and with increased concentration the morphology gradually changed from loose pellets to smaller compact ones.
Journal ArticleDOI
Concomitant biosynthesis of Aspergillus niger pectolytic enzymes and citric acid on sucrose
TL;DR: Pectolytic enzymes were synthesized during the cultivation of Aspergillus niger in a medium with decationized commercial sugar and it was shown that the remaining extracellular soluble dry matter was due to citric acid, which had been produced in amounts of up to 60 g l −1 thus constituting a useful by-product.

Effect of carbon sources on the synthesis of pectinase by Aspergilli
TL;DR: A. foetidus, NCIM 510, was the only one among the organisms studied, that responded well to the medium containing pectin in the absence of additional sugars supplied in the medium.
