Engineers here have used their patented fibrous-bed bioreactor to genetically alter a bacterium so that it produces 50 percent more of the chemical propionic acid than the organism produces normally.

Propionic acid is a valuable bio-based platform chemical utilised widely in the food, ... Traditionally produced through microbial fermentation using species such as Propionibacterium ...

FARGO, N.D. -- This year's poor growing conditions mean corn being harvested likely contains high levels of moisture with limited likelihood of further dry-down in the field.

The trials showed that the chitosan modified the ruminant fermentation in a manner that could turn out to be beneficial for the animal; for example, with increments in the production of propionic ...

Propionic acid is an end product of starch and sugar fermentation. Those animals fed sugar had significantly lower pH and less rumen propionate, whereas the lactic acid fed livestock had a higher ...

The study describes how elevated levels of the preservative, propionic acid (PPA)--used to extend shelf life and reduce mold in packaged foods, breads and cheeses—can adversely affect the ...
