Thermoregulation of Prodigiosin Biosynthesis by is Controlled at the Transcriptional Level and Requires HexS.

Several biotypes of the Gram-negative bacterium produce the tri-pyrole pigment and secondary metabolite prodigiosin. The biological activities of this pigment have therapeutic potential. For over half a century it has been known that biosynthesis of prodi giosin is inhibited when bacteria are grown at elevated temperatures, yet the fundamental mechanism underlying this thermoregulation has not been characterized.

Influence of interesterification of a stearic acid-rich spreadable fat on acute metabolic risk factors.

Chemical and enzymatic interesterification are used to create spreadable fats. However, a comparison between the two processes in terms of their acute metabolic effects has not yet been investigated. A randomised crossover study in obese (plasma TAG > 1.
