Detecting enzymatic activity: a test in full colour…

A patented device for the detection of enzymatic activity has been developed. It is based on the colours specific to the nanometric scale in biopolymer films. Rapid, simple and sensitive, this test could be miniaturised to enable its inclusion in high-throughout screening systems for applications in metagenomics, white biotechnologies, etc.

Refining the concept of precision protein to improve the efficiency of nitrogen utilization by piglets

The supply of dietary amino acids relative to the animal’s requirements is a main factor in the optimization of pig production systems. In a series of studies, we determined the requirements for valine, isoleucine, leucine and histidine in piglets. Knowledge of these requirements has been a limiting factor for the further reduction of the protein content in the diet and thus for reducing nitrogen excretion. We also showed that a valine deficiency results in a strong reduction of voluntary feed intake, which may be triggered by the early detection of metabolic signals in the blood

A probiotic whose “anti-stress” effects have been deciphered

Lactobacillus farciminis is a probiotic bacterial strain which reduces the permeability of the intestinal barrier, thus preventing passage into the blood circulation of bacterial products with inflammatory effects.
