Fractionation of the thylakoid membrane from Dunaliella salina – heterogeneity is found in Photosystem I over a broad range of growth irradiance
Autor: Per-Åke Albertsson, Claes Weibull, Eva Andreasson, Hreinn Stefánsson
Publikováno v: Biochimica et Biophysica Acta (BBA) - Bioenergetics. 1320:235-246
Thylakoids from the green alga, Dunaliella salina, were fragmented by sonication and the appressed grasna membranes separated from stroma lamellae by partitioning in aqueous two-phase systems. The concentration and antenna size of Photosystem I in th

Ultrastructure of spinach chloroplasts as revealed by freeze-substitution
Autor: Bernd Bohrmann, W. Villiger, Claes Weibull
Publikováno v: Journal of Structural Biology. 104:139-143
Unfixed and glutaraldehyde-fixed spinach chloroplasts were frozen on a copper block cooled by liquid helium and subsequently substituted in acetone at −87°C. Fixed chloroplasts were substituted in pure acetone, unfixed ones also in acetone contain

Physiological and Morphological Changes Induced by Nutrient Limitation of Pseudomonas fluorescens 378 in Continuous Culture
Autor: Claes Weibull, Göran Molin, Anders Persson
Publikováno v: Applied and Environmental Microbiology. 56:686-692
Pseudomonas fluorescens 378 was studied in continuous culture at a dilution rate of 0.05 or 0.15 h −1 and under a limitation of carbon/energy, nitrogen, phosphorus, iron(III), or oxygen. Cultures were examined for nutritional consumption, productio

High magnification scanning electron microscopy of bacterial cells and virions
Autor: Claes Weibull, Jarl Ekstrand
Publikováno v: Micron and Microscopica Acta. 21:139-143
When freeze-dried or critical point-dried cells of Escherichia coli and Bacillus sphaericus were coated with a 15 nm thick gold layer by means of sputtering, the surface of the bacteria appeared in the scanning electron microscope to consist of globu

The consumption of osmium tetroxide by components of the cytoplasmic membrane of Acholeplasma laidlawii and its morphological implications
Autor: Leif Rilfors, Claes Weibull
Publikováno v: Micron and Microscopica Acta. 16:77-83
The amounts of osmium tetroxide consumed by the double bonds of the unsaturated fatty acyl chains, by the lipid polar head groups and by proteins in the cytoplasmic membrane of Acholeplasma laidlawii were determined. Our results indicate that of the

Ultrastructure of spinach thylakoids as seen in low-temperature and conventional embeddings
Autor: Per-Åke Alertsson, Claes Weibull
Publikováno v: Journal of Ultrastructure and Molecular Structure Research. 100:55-59
Low-temperature embeddings of glutaraldehyde-fixed spinach chloroplasts were obtained by dehydrating the organelles with ethanol and infiltrating them with a Lowicryl resin at −35°C or below. Polymerization was achieved by uv light at the infiltra

Absence of an electron microscopic substructure in intact flagella of Proteus mirabilis and Bacillus subtilis
Autor: Claes Weibull, J. Czajkowski, V. Soltesz
Publikováno v: Journal of Ultrastructure Research. 46:79-86
Flagella of Proteus mirabilis D 52 appeared without any regular substructure in close to focus, high resolution electron micrographs of specimens negatively contrasted with potassium phosphotungstate or uranyl acetate. The same was true for many flag

Publikováno v: Journal of Ultrastructure Research. 73:233-244
Pea and spinach chloroplasts were fixed with glutaraldehyde and dehydrated with ethylene glycol at 0°C. In some experiments dehydration was achieved by the resin itself. The material was infiltrated at temperatures between −35 and 0°C with mixtur
