1,3-propanediol is used as a monomer in the production of some polymers e.g. polytrimethylene terephthalate used in the production of carpets and textile fibers and in the thermoplastics engineering. However, the traditional chemical synthesis is expensive, generates some toxic intermediates and requires a reduction step under high hydrogen pressure. Biological production of 1,3-propanediol cou...

Yarrowia lipolytica has been a valuable biotechnological workhorse for the production of commercially important biochemicals over 70 years. The knowledge gained so far on native biosynthetic pathways, as well availability numerous systems and synthetic biology tools, enabled not only regulation redesign existing metabolic but also introduction novel ones; further consolidating position yeast in...

Mixed oxides of ZnO and Cr2O3 with varied mole ratios were synthesized, characterized, evaluated for the dehydrocyclization crude glycerol production 2-methylpyrazine (2-MP). The Zn-Cr-O composition was optimized using bulk surface properties catalysts rationalized by BET-SA, XRD, XPS, H2-TPR, O2 pulse chemisorption, Raman spectroscopic techniques to achieve a high rate 2-MP.

The energy value of crude glycerin from different biodiesel production facilities was determined in nursery pigs (initial BW of 10.4 kg) to predict apparent DE and ME based on the composition of crude glycerin. Dietary treatments consisted of a basal diet, or diets containing crude glycerin from various biodiesel production facilities supplemented in the diet at approximately 9.1%. Because of b...
