   Abstract : Serpentinization is a metamorphic low-temperature geological process, involving a series of chemical reactions that hydrate ultramafic rocks into serpentines and other minerals such as magnetite and brucite. Moreover, the process produces heavily reducing and highly alkaline fluids together with molecular hydrogen (H2) and methane (CH4), which have the capacity to support chemosynthetic microbial life.

3. 2. Isolation and cultivation of methanogenic archaea from serpentinization system at Chimaera Seeps, Turkey

   University essay from SLU/Department of Molecular Sciences

   Author : Bobby Zetterlind; [2020]
   Keywords : Archaea; methanogens; Chimaera seeps; serpentinization system; isolation; cultivation;

   Abstract : A methanogenic archaeon was successfully isolated from iron-rich environmental samples from the Chimaera seeps in Turkey by cultivation in anoxic media supplemented with H2/CO2 and an antibiotic, namely erythromycin. The morphological features of this methanogen were non-motile rod cells approximately 1.7 – 8.5 μm in length and 0. READ MORE
