2. Search for Preserved Methanogenic Organisms in Ophiolitic Rocks through Lipid Biomarker Analysis – Implications for Astrobiological Explorations
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : 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.

5. Mainstream Deammonification process monitoring by bacterial activity tests
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. READ MORE
