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

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 ...

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 ...

Self-assembling biomaterials

Harm-Anton Klok

A new class of molecules for the preparation of self-assembling biomaterials were synthesized. These molecules consist of a cholesteryl-moiety attached via an oligo(ethylene oxide) or oligo(L-lactic acid) segment to a biologically relevant headgroup. The o ...

Phase equilibria of the decagonal AlCoNi phase

The phase equilibria of the ternary Al-AlCo-AlNi system were investigated around the decagonal phase. Isopleths with 70, 71.5 and 72.5 at.% Al and with 10 and 13 at.% Ni are elaborated with the aid of differential thermoanalysis, magnetothermal analysis, o ...

Optical microscopy in the nano-world

Olivier Martin, Abdeljalil Sayah, Mirjam Pfeiffer, Marc Jobin

Scanning near-field optical microscopy (SNOM) is an optical microscopy whose resolution is not bound to the diffraction limit. It provides chemical information based upon spectral, polarization and/or fluorescence contrast images. Details as small as 20 nm ...

The influence of pressure and temperature of compressed CO2 on the survival of yeast cells

Urs von Stockar, Ian William Marison

To study the potential use of supercrit. CO2 extn. for the recovery of products from yeast cell cultures, the effects of CO2 on different yeast strains over a range of pressures and temps. have been examd. Viability was shown to be dependent on temp. and d ...

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 ...

The effect of yeast extract supplementation on the production of lactic acid from whey permeate by Lactobacillus helveticus

Urs von Stockar

Batch and continuous 2-stage cultures were conducted to det. the effect of yeast ext. (YE) on the homolactic fermn. of whey permeate by L. helveticus. Supplementation with YE had a significant effect on lactic acid concn., volumetric productivity, and subs ...

Fermentation control and the use of calorimetry

Urs von Stockar, Ian William Marison

A novel heat-flux calorimeter was used to study the growth of Kluyveromyces fragilis on a variety of C substrates. Heat liberated was directly related to biomass formed and also to O2 consumed. Heat yield coeffs. derived from these relationships allowed th ...
