Paper made from bleached chemithermomechanical pulp (Cq'MP) was treated with UV absorbers, e.g. 2,4-dihydroxybenzophenone and a 2-(2-hydroxyphenyl)benzotriazole derivative (Tinuvin 1130) to reduce the tendency of the paper to undergo photoyellowing. Whilst some of the UV absorbers offer some protect

## 2,4_dihydroxybenzophenone (DHB) is known to be a reasonably efficient UV screen for preventing the colour reversion of papers made from high-yield pulps. Attempts have been made to improve the performance of this material by increasing its compatibility with cellulose and by the introduction of
## Abstract A novel three stages continuous fermentation process for the bioproduction of succinic acid at high concentration, productivity and yield using __A. succiniciproducens__ was developed. This process combined an integrated membrane‐bioreactor‐electrodialysis system. An energetic character
