Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii
Advanced Science, EarlyView.Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.

Structural Changes in Polyaniline upon Reaction with DPPH
e-Journal of Surface Science and Nanotechnology, 2009 Polyaniline (PANI) powder was prepared using ammonium persulfate (APS) as the oxidant with an APS to aniline (ANI) ratio of 1.5. The powder was then reduced by hydrazine or dedoped using an aqueous ammonium solution. The antioxidant properties of these polymers were investigated through their reaction with the stable and intensely coloured DPPH radical.

ChemInform Abstract: THE PROTON MAGNETIC RESONANCE IN THE DPPH‐BENZENE COMPLEX [PDF]
Chemischer Informationsdienst, 1974 Abstract The proton magnetic resonance in single crystals of the DPPH–benzene complex has been measured around three Cartesian axes. All the spectra are highly complex, but some lines are clearly identified around all axes. The principal values of their anisotropic hyperfine tensors have been evaluated, in addition to the isotropic ...
