Anaerobic sludge granulation at high salinity
Industries, such as leather tanning, agro-food, fisheries, petroleum, petrochemical and textile dyeing produce saline wastewater. As a result approximately 5% of the globally generated wastewater is hypersaline (salinity above 3.5%). Because salts have a negative effect on microbial activity, biological treatment processes are usually not considere...
Sustainable protein technology : an evaluation on the STW Protein programme and an outlook for the future
In 2013 a new STW research programme was started on sustainable protein recovery. This STW Protein Programme consisted of five sustainable protein technology projects, which aimed at developing innovative methods to extract proteins from plant leaves, microalgae and insects to meet the increasing demand for food proteins for humans and livestock. T...
Of proteins and processing: mechanisms of protein damage upon rapeseed processing and their effects on nutritional value...
Hydrothermal processing is a common practice during the manufacture of protein-rich feed ingredients, such as rapeseed meal (RSM), and feeds. This processing step can induce physical and chemical changes to the proteins, thereby reducing the digestibility and utilization of crude protein (CP) and amino acids (AA). Whilst most literature has linked ...
In vivo 1H NMR methods to study dynamics of chloroplast water and thylakoid membrane lipids in leaves and in photosynthe...
Dynamics of thylakoid membranes and mobility of pigment-protein complexes therein are essential for survival of photosynthetic organisms under changing environmental conditions. The published approaches to probe mobility of the thylakoid membrane lipids and protein complexes are either dependent on the use of external labels or are used only for in...
Leaf phenolics and seaweed tannins : analysis, enzymatic oxidation and non-covalent protein binding
Upon extraction of proteins from sugar beet leaves (Beta vulgaris L.) and oarweed (Laminaria digitata) for animal food and feed purposes, endogenous phenolics and proteins can interact with each other, which might affect the protein’s applicability. Sugar beet leaf proteins might become covalently modified by phenolics through polyphenol oxidase (P...
Structuring oil by protein building blocks
Over the recent years, structuring of oil into ‘organogels’ or ‘oleogels’ has gained much attention amongst colloid-, material,- and food scientists. Potentially, these oleogels could be used as an alternative for saturated- and trans fats in food products. To develop oleogels as a suitable replacement for saturated fats, the requirements go beyond...
Sugar beet leaves: from biorefinery to techno-functionality
Sugar beet leaves (SBL), which are a side stream of the sugar beets cultivation, are currently left unexploited after sugar beets have been harvested. The general aim of this thesis was to study the biorefinery of SBL, with a special focus on the isolation of proteins. To reach this aim the research was divided into three sub-aims: 1) to determine ...
Studying fast dynamics in biological complexes : from photosynthesis in vivo to single DNA molecules in vitro
During the last decades, fluorescence spectroscopy has emerged as a powerful tool in the fields of biophysics, biotechnology, biochemistry, cellular biology and the medical sciences. These techniques are highly sensitive, and allow us to study the structure and dynamics of (bio)molecular systems (Valeur 2001). A significant advantage of fluorescenc...
FeedOmics, an approach to evaluate the functional properties of protein containing feed ingredients
This thesis presents FeedOmics approach as a toolkit, to evaluate (novel) protein containing feed ingredients of different origin considering both their nutritional and functional value in terms of their capacity to support or modify nutrient supply, the animal’s physiology, tissue development and functioning. Such knowledge may contribute to intro...
