The right-handed parallel β-helix topology of Erwinia chrysanthemi pectin methylesterase Is intimately associated with both sequential folding and resistance to high pressure Universiteit Antwerpen

Filip Meersman
The complex topologies of large multi-domain globular proteins make the study of their folding and assembly particularly demanding. It is often characterized by complex kinetics and undesired side reactions, such as aggregation. The structural simplicity of tandem-repeat proteins, which are characterized by the repetition of a basic structural motif and are stabilized exclusively by sequentially localized contacts, has provided opportunities for ...

Insects as an alternative source for the production of fats for cosmetics Universiteit Antwerpen KU Leuven

Geert R. Verheyen, Tom Ooms, Liesbeth Vogels, Steven Vreysen, Ann Bovy, Sabine Van Miert, Filip Meersman
Insects may provide an environmentally friendly way of producing high-quality bio-based materials that can be implemented for cosmetic applications. Insects can be bred on organic waste, in high numbers, and on small surfaces, therefore, making large scale industrial breeding possible. Fats from three insect species: the black soldier fly (BSF) (Hermetia illucens), the locust (Locusta migratoria), and the house cricket (Acbeta domesticus) were ...

Water dynamics in Shewanella oneidensis at ambient and high pressure using quasi-elastic neutron scattering Universiteit Antwerpen

Fabrizia Foglia, Rachael Hazael, Giovanna G. Simeoni, Marie-Sousai Appavou, Martine Moulin, Michael Haertlein, V. Trevor Forsyth, Tilo Seydel, Isabelle Daniel, Filip Meersman, et al.
Quasielastic neutron scattering (QENS) is an ideal technique for studying water transport and relaxation dynamics at pico-to nanosecond timescales and at length scales relevant to cellular dimensions. Studies of high pressure dynamic effects in live organisms are needed to understand Earth's deep biosphere and biotechnology applications. Here we applied QENS to study water transport in Shewanella oneidensis at ambient (0.1 MPa) and high (200 ...

Exploring the pressure-temperature behaviour of crystalline and plastic crystalline phases of N-isopropylpropionamide Universiteit Antwerpen KU Leuven

Filip Meersman
The phase behaviour of crystalline and plastic crystalline phases of N-(isopropyl) propionamide (NiPPA) has been investigated by X-ray diffraction and a tentative P,T diagram has been constructed. The observed phase transitions are highly dependent on kinetics, and metastable co-existence of both phases can be observed. At lower pressures (up to 400 MPa) the plastic crystalline phase transforms into the crystalline phase as observed for other ...

Laboratory investigation of high pressure survival in Shewanella oneidensis MR-1 into the gigapascal pressure range Universiteit Antwerpen

Rachael Hazael, Fabrizia Foglia, Liya Kardzhaliyska, Isabelle Daniel, Filip Meersman, Paul McMillan
The survival of Shewanella oneidensis MR-1 at up to 1500 MPa was investigated by laboratory studies involving exposure to high pressure followed by evaluation of survivors as the number (N) of colony forming units (CFU) that could be cultured following recovery to ambient conditions. Exposing the wild type (WT) bacteria to 250 MPa resulted in only a minor (0.7 log N units) drop in survival compared with the initial concentration of 10(8) ...
