Buffering agent for pH control during in situ bioremediation of chlorinated solvent source zones

David Andrew Barry, Christof Holliger, Elsa Marina Lacroix

Chloroethenes such as tetrachloroethene (PCE) and trichloroethene (TCE) are among the most prevalent contaminants in groundwater. Because of their low aqueous solubility, PCE and TCE are often present as dense non aqueous phase liquid (DNAPL) that can act ...

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 ...

On-Line Recalibration of Spectral Measurements Using Metabolite Injections and Dynamic Orthogonal Projection

Urs von Stockar, Michael Amrhein, Pamandeep Singh Gujral, Michal Dabros

Spectrometers are enjoying increasing popularity in bioprocess monitoring due to their non-invasiveness and in-situ sterilizability. Their on-line applicability and high measurement frequency create an interesting opportunity for process control and optimi ...

Hydrogen production by Clostridium thermolacticum during continuous fermentation of lactose

Jean-Paul Schwitzguebel, Nevenka Adler, Christophe Collet

In the production of acetate by Clostridium thermolacticum growing on lactose, considerable amounts of hydrogen were generated. Lactose available in large amounts from milk permeate, a wastestream of the dairy industry, appears to be a valuable substrate f ...

Peptides derived from sodium caseinate Hydrolysates produced by Lactobacillus helveticus NCC 2765

Angiotensin-I-converting enzyme (ACE) inhibitory activity was identified in milk proteins fermented with Lactobacillus (Lb.) helveticus NCC 2765 (Nestle Culture Collection, Vers-chez-les-Blanc, Switzerland). Hydrolyzing sodium caseinate for 1 and 2 h inhib ...

Quantitative analysis of the regulation scheme of invertase expression in Saccharomyces cerevisiae

Urs von Stockar, Ian William Marison, Christoph Herwig

In Saccharomyces cerevisiae, the expression of invertase, which is the hydrolyzing enzyme of sucrose, is controlled by the presence of monosaccharides, such as glucose and fructose, and referred to as carbon catabolite repression. To date, efforts have bee ...

A process for the in-situ extraction of fermentation broths

Urs von Stockar, Ian William Marison

A process is provided for the in-situ extn. of a fermn. product esp. for products which result from the transformation of an amino acid and which are sol. in the fermn. broth. The sol. product is then removed from aq. phase by extn. into an org. phase wher ...

Fermentation by gut microbiota cultured in a simulator of the human intestinal microbial ecosystem is improved by supplementing a soygerm powder

Bart Deplancke

An in vitro model, designated the Simulator of the Human Intestinal Microbial Ecosystem (SHIME), was used to study the effect of a soygerm powder rich in beta-glycosidic phytoestrogenic isoflavones on the fermentation pattern of the colon microbiota and to ...

Glycerol production by yeast fermentation of whey permeate

Urs von Stockar, Ian William Marison

Yeast strains were examd. for their ability to produce glycerol, and Kluyveromyces marxianus NRRLY-665 was chosen for further optimization due to its comparatively high growth rate (0.15/h) and glycerol yield (9.5% by wt. on lactose) at 37 Deg and pH 7. Op ...
