Scientific Opinion on the safety and efficacy of l-threonine produced by fermentation with Escherichia coli CGMCC 11473 for all animal species. EFSA Journal 2017;15(7):4939, 16 pp. Research Institute for Agriculture, Fisheries and Food
Scientific opinion on the safety of L-threonine, technically pure, produced by fermentation with Escherichia coli CGMCC 7.58 for all animal species based on a dossier submitted by Feedway Europe NV Research Institute for Agriculture, Fisheries and Food
Room temperature Q-band electron magnetic resonance study of radicals in X-ray-irradiated L-threonine single crystals Ghent University
In the past, decennia radiation-induced radicals were successfully identified by electron magnetic resonance (EMR) in several solid-state amino acids and sugars. The authors present a room temperature (RT) EMR study of the stable radicals produced by X-ray-irradiation in the amino acid l-threonine (CH3CH(OH)CH(NH3+)COO-). Its chemical structure is similar to that of the well-known dosimetric material l-alanine (CH3CH(NH3+)COO-), and radiation ...

Copper(II) 15-metallacrown-5 lanthanide(III) complexes derived from L-serine and L-threonine hydroxamic acids KU Leuven
Formation of pentanuclear copper(II) complexes with serine hydroxamic acid (Serha) and threonine hydroxamic acid (Thrha) was studied in solution by electrospray ionization mass spectrometry (ESI-MS), absorption spectrophotometry and proton NMR spectroscopy. The presence of lanthanide(III) ions is essential for the self-assembly of the 15-metallacrown-5 compounds. The positive mode ESI-MS spectra of the solutions containing Serha or Thrha, ...

Safety and efficacy of l-threonine produced using Escherichia coliCGMCC 13325 as a feed additive for all animal species Research Institute for Agriculture, Fisheries and Food
Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on l-threonine produced by fermentation when used as a nutritional additive in feed and water for drinking for all animal species and categories. The product under assessment is l-threonine produced using a genetically modified strain of E. coliCGMCC 13325. The ...
