- ... Some approaches for improving recombinant phenylalanine ammonia lyase (PAL) stability in Escherichia coli during the enzymatic methods of l-phenylalanine (l-Phe) production were developed following preliminary studies by means of statistical-based experiment designs (response surface method). The traditional non-statistical technology was used to screen four critical factors for PAL stability duri ...

Novel polythiophene derivatives with azobenzene chromophore side chains, poly[3-(6-((4-phenylazo)phenoxyl)hexyl)thienylacetate] (PATh-6), and the copolymers of 3-(6-((4-phenylazo)phenoxyl)hexyl)thienylacetate with 3-alkylthiophenes including 3-hexylthiophene and 3-dodecylthiophene (COP-66 and COP-612) were synthesized. The structure and the thermal property of these polythiophene derivatives were ...
