Complex systems are systems whose behaviour is a result of various interacting elements. Understanding the behaviour is such complex systems is notoriously hard. In this thesis I apply known tools in new situations to answer questions about the dynamics of complex systems, related to resilience, causality and complexity itself.

Presence of persistent organic compounds and salinity in the industrial wastewater hindering their reuse within the industry. Advanced oxidation technology can effectively remove the organic compounds; however, their performance is influenced by salinity. The influence of salinity on advanced oxidation technologies and their minimization strategies has been thoroughly studied in the thesis.

Zooming into the sponge microbiome: Characterization of sponge-associated microorganisms in the multi-omics era

Marine sponges represent an excellent example of host-microbe symbiosis. Yet, most sponge-associated microorganisms remain uncultured, hampering efforts in determining interactions with their sponge host. This thesis aimed at enhancing our understanding of the sponge-bacteria interplay, focusing on both cultured and yet-uncultured sponge-associated lineages. Several novel sponge-associated taxa were elucidated by resolving their phylogeny and reconstructing their primary and secondary metabolism. Genome-based predictions revealed that the sponge microbiome mediates the interactions of the holobiont via heterotrophy, potential metabolite exchange and chemical defense. Sponge symbionts also possessed an extended genomic repertoire of defense systems implying adaptation to host environment. Moreover, genome mining for biosynthetic gene clusters (BGCs) and bioactivity screening of sponge-associated strains detected many candidate BGCs potentially involved in observed anticancer and antibacterial activity. Altogether, this work shed light into novel sponge-associated phylotypes, features that point at a symbiotic lifestyle and a rich secondary metabolite biosynthesis arsenal with biotechnological potential.

Thermophilic and hyper-thermophilic anaerobic digestion as novel treatment technologies for safe nutrient recovery from concentrated black water

  • 8 April, 2022
  • 11:00
  • Wageningen University, Environmental Technology
  • prof. dr CJN Buisman
  • dr ir MHA van Eekert

Human excreta contain a lot of nutrients like nitrogen, phosphorous and potassium which are mainly wasted while agriculture mainly relies on nutrients from artificial fertilizers. However, these nutrient sources are limited and have a large impact on the environment. For instance, nitrogen fixation is very energy intensive and phosphorous rock mining results in heavy metal pollution. Human excreta end up in the waste water treatment plant as part of domestic waste water. By source separation, toilet water (black water), bathroom water (grey water) and rainwater are separated. Nutrients end up in the concentrated black water stream, but also a large fraction of pharmaceuticals and pathogen are present in black water. Therefore, thermophilic and hyper-thermophilic anaerobic digestion are proposed to simultaneously recover the nutrients from black water and eliminate pathogens and pharmaceuticals to ensure safety with regards to public health upon reuse of recovered products.
