Structure and properties of La-modified Na0.5Bi0.5TiO3 at ambient and elevated temperatures

Dragan Damjanovic

The crystal structure and property changes of sodium bismuth titanate (Na0.5Bi0.5TiO3, NBT) piezoelectric ceramics are reported as a function of La modification (0.5-2.0 at. %) and increasing temperature using high resolution x-ray diffraction, permittivit ...

Fuel bioethanol production from whey permeate

François-Nicolas de Glutz

The objective of this thesis was to evaluate the feasibility for the production of fuel bioethanol from whey permeate. The identification of the limiting factors of the process revealed that the stabilization of the substrate was critical to the use of whe ...

Anode dusting during the electrolytic production of aluminium

Timea Tordai

The disintegration of the carbon anodes during the electrolysis of alumina produces dust particles contaminating the electrolytic bath. This phenomenon, called dusting, is one of the most deleterious Al electrolysis failures, as it leads to a significant d ...

Immobilization as a tool to control fermentation in yeast-leavened refrigerated dough

Urs von Stockar, Ian William Marison, Véronique Breguet, Raphaël Gugerli

In order to extend the shelf life of refrigerated dough, a new method based on thermo-gelling immobilization is proposed. This slows fermn. at low temps. (

Control of yeast fed-batch process through regulation of extracellular ethanol concentration

Urs von Stockar, Sergio Valentinotti, Christopher Cannizzaro

At high growth rates, the biomass yield of baker's yeast (Saccharomyces cerevisiae) decreases due to the prodn. of ethanol. For this reason, it is std. industrial practice to use a fed-batch process whereby the specific growth rate, m, is fixed at a level ...

Metabolic network analysis on Phaffia rhodozyma yeast using 13C-labeled glucose and gas chromatography-mass spectrometry

Urs von Stockar, Christopher Cannizzaro, Jens Nielsen

Carotenoid prodn. by microorganisms, as opposed to chem. synthesis, could fulfill an ever-increasing demand for 'all natural' products. The yeast Phaffia rhodozyma has received considerable attention because it produces the red pigment astaxanthin, commonl ...

On-line biomass monitoring with scanning dielectric spectroscopy

Urs von Stockar, Ian William Marison, Sergio Valentinotti, Christopher Cannizzaro

Accurate online monitoring of biomass is an enduring problem. Of the various methods available, one of the more satisfactory is with dielec. spectroscopy (often referred to as capacitance monitoring). However, as this technique measures total -biovolume', ...

Extractive Bioconversion of 2-Phenylethanol from L-Phenylalanine by Saccharomyces cerevisiae

Urs von Stockar, Ian William Marison

The bioconversion of L-phenylalanine (L-Phe) to 2-phenylethanol (PEA) by the yeast Saccharomyces cerevisiae is limited by the toxicity of the product. PEA extn. by a sep. org. phase in the fermenter is the ideal in situ product recovery (ISPR) technique to ...
