De lectorale rede gehouden door Janneke Krooneman tijdens haar lectorinstallatie op 5 april.

Lezing Lectorenplatform Biobased Economy: Lezing voor nieuwe fermentatiewerkgroep waar Janneke Krooneman de voorzitter van is.

Growth conditions have been frequently studied in optimizing polyhydroxybutyrate (PHB) production, while few studies were performed to unravel the dynamic mixed microbial consortia (MMCs) in the process. In this study, the relationship between growth conditions (C/N ratios and pH) and the corresponding …

Kombucha is a drink made from fermented sweetened tea. Kombucha has a sweet and sour taste, it is slightly sparkling and in recent years, the drink has become increasingly popular in the western world. This surge in popularity is in part due to the supposed health benefits. The exact chemical composition …

The sustainable provision of enough nutritious food for a growing world population is pushing the food system towards finding new approaches to agriculture (Ockenden, et al., 2017). While the demand of animal products is rising (Armanda, Guinée, & Tukker, 2019), the negative effect on the climate, soil, …

High-pressure anaerobic digestion is an appealing concept since it can upgrade biogas directly within the reactor. However, the decline of pH caused by the dissolution of CO2 is the main barrier that prevents a good operating high-pressure anaerobic digestion process. Therefore, in this study, a high-pressure …

A bioaugmentation approach was used to enhance the performance of anaerobic digestion (AD) using cow manure (CM) as the substrate in a continuous system. To obtain the desirable microbial culture for bioaugmentation, a biochemical methane potential test (BMP) was used to evaluate three commonly used …

Many articles have been published on scale-down concepts as well as additive manufacturing techniques. However, information is scarce when miniaturization and 3D printing are applied in the fabrication of bioreactor systems. Therefore, garnering information for the interfaces between miniaturization …

It is of utmost importance to collect organic waste from households as a separate waste stream. If collected separately, it could be used optimally to produce compost and biogas, it would not pollute fractions of materials that can be recovered from residual waste streams and it would not deteriorate …

n the work package described in this report, members are investigating whether a cooperative of farmers can become self-sufficient in energy and fertilization by using manure and organic waste flows in combination with anaerobic fermentation. The aim is to link the nutrient cycle (from manure to digestate …
