Saline Systems 6:10. 2010..However, studies focused on the characterization of inland solar salterns are scarce and both the archaeal diversity and the plant communities inhabiting these environments remain poorly described...
2-Hydroxyacid dehydrogenase from Haloferax mediterranei, a D-isomer-specific member of the 2-hydroxyacid dehydrogenase familyM J Bonete
Departamento de Bioquimica, Facultad de Ciencias, Universidad de Alicante, Ap 99, Alicante, Spain
Biochimie 82:1143-50. 2000..5 and 8.5. The optimum temperature was 52 degrees C and at 65 degrees C there was a pronounced activity decrease. This new enzyme can be used for the production of D-2-hydroxycarboxylic acid...
Alpha-amylase activity from the halophilic archaeon Haloferax mediterraneiF Perez-Pomares
División de Bioquímica, Facultad de Ciencias, Universidad de Alicante, Apartado 99, 03080 Alicante, Spain
Extremophiles 7:299-306. 2003..The enzyme displayed maximal activity at pHs from 7 to 8, and its optimal temperature was in a range from 50 degrees C to 60 degrees C. The results also implicated several prototropic groups in the catalytic reaction...
