L-Arabinose degradation pathway in the haloarchaeon Haloferax volcanii involves a novel type of L-arabinose dehydrogenase.

The pathway of L-arabinose degradation was studied in the haloarchaeon Haloferax volcanii. It is shown that L-arabinose is oxidatively degraded to α-ketoglutarate. During growth on L-arabinose, L-arabinose dehydrogenase (L-AraDH) was induced.

Recognition of Clostridium difficile PCR-ribotypes 001, 027 and 126/078 using an extended MALDI-TOF MS system.

During the last decade, Clostridium difficile infection (CDI) increased markedly inside as well as outside of hospitals. In association with the occurrence of new hypervirulent C. difficile strains, CDI became more important.

D-xylose degradation pathway in the halophilic archaeon Haloferax volcanii.

The pathway of D-xylose degradation in archaea is unknown. In a previous study we identified in Haloarcula marismortui the first enzyme of xylose degradation, an inducible xylose dehydrogenase (Johnsen, U., and Schönheit, P.
