Accumulation of non-degradable plastic waste in the environment might be prevented by the use of biodegradable polyhydroxyalkanoate (PHA). In this study, the thermophile Schlegelella thermodepolymerans produced up to 80 wt% PHA based on dry cell mass. The largest PHA granules were found in the cells …

Dairy and other animal products play an important role in the diet of the majority of the population. However, there are a lot of sustainability concerns regarding dairy production due to high environmental impacts. Therefore, there is a need to develop a more sustainable dairy substitute. One of the …

Veel van de grondstoffen die we gebruiken voor de miljoenen producten die we produceren zijn niet duurzaam. Ze zijn eindig, fossiel en zeer vervuilend. Daarom zijn er nieuwe duurzame alternatieven nodig die we dagelijks kunnen inzetten bij de productie én na gebruik kunnen terugbrengen in een kringloop …

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 …
