The formation of exopolysaccharides (EPS) by Pediococcus damnosus strain 2.6 was investigated in two different high P-glucan suspensions of oat (OBC) and barley (BBC). Bacterial growth was confirmed by measuring pH, colony forming units (cfu), viscosity and ropiness during growth. Growth and an increase in viscosity of the beta-glucan suspension based on oat were observed whereas only a minor grow

Flux reductions experienced during ultrafiltration are due either to concentration polarization or fouling. It is usually difficult to distinguish between these two phenomena, but by using a turbulence-promoting module it is possible to determine the reversibility of a flux reduction, and thus distinguish between concentration polarization and fouling. By using a turbulence-promoting module, it is

There are few studies on the microclimate and human comfort of urban areas in hot dry climates. This study investigates the influence of urban geometry on outdoor thermal comfort by comparing an extremely deep and a shallow street canyon in Fez, Morocco. Continuous measurements during the hot summer and cool winter seasons show that, by day, the deep canyon was considerably cooler than the shallow

Objective: To study antibodies to cyclic citrullinated peptides (anti-CCP) and rheumatoid factor in patients with active, severe extra-articular rheumatoid arthritis (ExRA) compared with controls without ExRA. Methods: 35 consecutive patients with severe ExRA manifestations according to predefined criteria were studied. 70 patients with rheumatoid arthritis, but no ExRA manifestations, individuall

In 1993-1998 the lichen flora of Stora Karlso and Lilla Karlso was surveyed. These two nearby islands are situated outside the west coast of Gotland, Sweden, in the Baltic Sea. In all, 355 species were found, including three lichenicolous fungi. Two species are new to Sweden, viz. Lepraria flavescens and Placynthium lismorense. Both were found on limestone. The number of species according to habit

Popular Abstract in Swedish Cytokromer bär hem som prostetisk grupp och ingår i den energi givande andningskedjan. Cytokromer namnges beroende på strukturen av den hem-molekyl som respektive cytokrom bär. Cytokrom av a-typ innehåller hemA, cytokrom av b-typ innehåller hemB osv. Cytokrom av c-typ skiljer sig från övriga cytokrom genom att ha hemgruppen kovalent bunden till proteinet. Syntes av baktCytochromes function in electron transfer reactions, e.g. in respiratory systems, and contain haem as a prosthetic group. Cytochromes of the c-type differ from other cytochromes in that haem is covalently attached, via thioether linkages, to two cysteine residues in a conserved sequence motif in the protein, Cys-Xaa-Yaa-Cys-His. The functional location of c-type cytochromes in bacteria is on the o

Popular Abstract in English A handful of diseases-causing pathogenic microorganisms claim millions of lives worldwide each year, mainly due to limited diagnostic capabilities. The lack of simple, cost-effective, sensitive and rapid on-site diagnostic tools lead to delays in the diagnoses with a subsequent lag in treatment, which in turn can result in serious complications or even loss of lives. Fast and sensitive detection of pathogenic microbial cells is a highly important task in medical diagnostics, environmental analysis and evaluation of food safety. Accordingly, the idea of microorganism identification by the recognition of specific DNA sequence using electrochemical technique is one of the leading researches in the development of diagnostic devices. In other words, it should only

My article deals with the work of the St Joseph Sisters in the Nordic countries, particularly in Denmark and Sweden, from the sisters’ arrival in 1856 to the 1920:ies. These Catholic sisters belonged to a French congregation called "La Congregation des Sœurs de Saint-Joseph de Chambéry", which was founded at the beginning of the nineteenth century and whose motherhouse was in Chambéry in Savoy.
