TLDR
In order to develop a two-stage inoculum possessing the best conditions for the maximum production of all three enzymes, a multiresponse analysis was carried out using a generalized distance approach.About:

Characterization of three-phase partitioned exo-polygalacturonase from Aspergillus sojae with unique properties
Nergiz Dogan,Canan Tari +1 more
TL;DR: In this paper, the enzyme was characterized with respect to its activity and stability at various pH and temperature ranges using SDS-PAGE profiling, which revealed that the enzyme had two bands with the molecular weights of 36 and 53 kDa.
Journal ArticleDOI
Biochemical and thermal characterization of crude exo-polygalacturonase produced by Aspergillus sojae
TL;DR: In this article, a crude exo-polygalacturonase enzyme (produced by Aspergillus sojae) was characterized with respect to its biochemical and thermal properties.
Journal ArticleDOI
Microbial pectic transeliminases.
TL;DR: The yields of pectic transeliminases are less than other pectinases, and an improved process for the production of these enzymes is necessary.
Journal ArticleDOI
Valorization of wheat bran for the production of polygalacturonase in SSF of Aspergillus sojae
Hande Demir,Canan Tari +1 more
TL;DR: In this article, wheat bran, among various agro industrial by products, screened for the production of polygalacturonase (PG) in solid-state fermentation of Aspergillus sojae mutant strain, was found to be the most suitable substrate without the addition of any nutritive or inducing supplement.
Journal ArticleDOI
Pectinase Activity Determination: An Early Deceleration in the Release of Reducing Sugars Throws a Spanner in the Works!
Alessandra Biz,Fernanda Cardoso Farias,Francine Aline Motter,Diogo Henrique de Paula,Peter Richard,Nadia Krieger,David A. Mitchell +6 more
TL;DR: It is shown, for the first time, that a significant deceleration of the rate of liberation of reducing sugars occurs over the first ten minutes of the reaction, and it is shown that the relative activities obtained with polygalacturonic acid do not correlate with those obtained with pectin.

On the Experimental Attainment of Optimum Conditions
George E. P. Box,K. B. Wilson +1 more
TL;DR: The work described in this article is the result of a study extending over the past few years by a chemist and a statistician, which has come about mainly in answer to problems of determining optimum conditions in chemical investigations, but they believe that the methods will be of value in other fields where experimentation is sequential and the error fairly small.

Response surfaces : designs and analyses
John A. Cornell,André I. Khuri +1 more
TL;DR: In this paper, the authors present a methodology for estimating response surfaces that rival least squares based on the integrated mean squared error criterion analysis of multiresponse experiments with block effects mixture designs and analyses nonlinear response surface models.

Multi-Factor Experimental Designs for Exploring Response Surfaces
George E. P. Box,J. S. Hunter +1 more
TL;DR: In this paper, the concept of the variance function for an experimental design is introduced, and the problem of selecting practically useful designs is discussed, and in this connection, the notion of variance function is introduced.
