- The activity of denitrifying methanotrophic bacteria at 11-30 °C was assessed in short-term experiments. The aim was to determine the feasibility of applying denitrifying methanotrophic bacteria in low-temperature anaerobic wastewater treatment. This study showed that biomass enriched at 21 °C had an optimum temperature of 20-25 °C and that activity dropped as temperature was increased to 30 °C. Biomass enriched at 30 °C had an optimum temperature of 25-30 °C. These results indicated that biomass from low-temperature inocula adjusted to the enrichment temperature and that low-temperature enrichment is suitable for applications in low-temperature wastewater treatment. Biomass growth at ≤20 °C still needs to be studied.

- Sustainability transitions are commonly considered impossible without regime change. Theoretical work on regime change has mainly focused on niches and landscapes and less on change ‘from within’. Empirical analysis helps theorising endogenous regime change. Conceptualising regimes as semi-coherent entities composed of multiple ‘institutional logics’, we analyse the endogenous regime change in Dutch dairy farming. Practices in this sector have become more and more market-driven. This dominant logic however was increasingly challenged by institutional logics centring round cultural identity and sustainability. Tensions particularly centred round the increased indoor housing of cows. The contestation of this practice eventually led to a first ‘crack’ in the regime, as it weakened the dominance of the market logic and enabled opportunities for more sustainability. Our case study shows that the presence of alternative institutional logics is necessary to crack the regime, but opportunities to patch it back together are similarly crucial to enable sustainability transitions.
