Multi response optimization for enhanced xylitol production by Debaryomyces nepalensis in bioreactor
TL;DR: B batch fermentation at optimal operating conditions resulted in enhanced productivity (0.76 g L−1 h−1), xylitol concentration and yield and a increase of 76.74 % ofxylitol productivity.
Journal ArticleDOI
Characterisation of pectin and optimization of pectinase enzyme from novel Streptomyces fumigatiscleroticus VIT-SP4 for drug delivery and concrete crack-healing applications: An eco-friendly approach.
TL;DR: The ability of actinomycete spores to survive and they react to form calcite complex directly helps in crack healing process and this low-cost microbial pectinase can be used in drug delivery and concrete crack-healing applications sectors in future.

Evaluation of orange peel, an industrial waste, for the production of Aspergillus sojae polygalacturonase considering both morphology and rheology effects
Nihan Göğüş,Bengi Hakguder Taze,Hande Demir,Canan Tari,Sevcan Unluturk,Marcelo Fernandez Lahore +5 more
TL;DR: The low pH trend observed during the course of the fermentation was another important positive outcome for industrial fermentations, prone to contamination problems, and was investigated in the serial bioreactor system using the optimized medium composition.

New Method for the Immobilization of Glutaryl-7-Aminocephalosporanic Acid Acylase on a Modified Epoxy/Silica Gel Hybrid.
TL;DR: In this article, a new immobilization method for glutaryl-7-aminocephalosporanic acid (ACA) acylase was introduced, where a strong alkaline reagent was used as a spacer after epoxide silanization, and followed by glutaraldehyde as a crosslinking agent.

The effect of process parameters in enhancement of lipase production by co-culture of lactic acid bacteria and their mutagenesis study
Sita Ramyasree,Jayati Ray Dutta +1 more
TL;DR: The objective of this work was to select the best possible combination of lipase producing bacteria of Lactococcus lactis and Lactobacillus brevis, or Lactoblacillus plantarum for the optimum production of this enzyme using olive oil as a substrate.

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.
