Open AccessCo-cultures with integrated in situ product removal for lactate-based propionic acid production
Propionic acid (PA) is a valuable organic acid for the food and feed industry, but no bioproduction at industrial scale exists so far. As product inhibition is a major burden for bioprocesses producing organic...

Open AccessSubstrates and oxygen dependent citric acid production by Yarrowia lipolytica: insights through transcriptome and fluxome analyses
Unlike the well-studied backer yeast where catabolite repression represents a burden for mixed substrate fermentation, Yarrowia lipolytica, an oleaginous yeast, is recognized for its potential to produce single c...

Open AccessMetabolic and proteomic analyses of product selectivity and redox regulation in Clostridium pasteurianum grown on glycerol under varied iron availability
Clostridium pasteurianum as an emerging new microbial cell factory can produce both n-butanol (BuOH) and 1,3-propanediol (1,3-PDO), and the pattern of product formation changes signifi...

Open AccessFermentation of mixed substrates by Clostridium pasteurianum and its physiological, metabolic and proteomic characterizations
Clostridium pasteurianum is becoming increasingly attractive for the production of chemicals and fuels such as n-butanol and 1,3-propanediol. Previously we have shown that dual substra...

The Use of a C-FOS-GFP Reporter System for Monitoring Apoptosis of Animal Cells Induced by Exotoxins of Pseudomonas Aeruginosa
A reporter gene system based on the expression of green fluorecense protein (GFP) was developed for monitoring the dynamics of apoptotic cell death. The expression plasmid was stably introduced into CHO-DHFR− cel...
