  1. 1. Bacterial Activity and Community Composition in the Rhizosphere. Influence of plant species, root age, nitrogen addition and mycorrhizal status

    Author : Katarina Söderberg; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CLPP; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Biolog; PLFA; mycorrhizal status; nitrogen addition; along roots; plant species; root age; thymidine and leucine incorporation; bacterial composition; Rhizosphere; bacterial activity;

    Abstract : Microbial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. READ MORE

    Abstract : To what extent the environmental history of the Arctic can move beyond thedivide between Indigenous peoples and newcomers or vernacular and academicways of knowing? The present dissertation answers this question by developing thenotion of an environmental archive. Such an archive does not have particular referenceto a given place but rather it refers to the complex network that marks the relationsbetween paper documents and human and non-human agencies as they are able towork together and stabilise the conceptualisation of a variety of environmentalobjects.

  4. 4. Characterization of Aeromonas, Enterobacteriaceae, Pseudomonas, Bacillus and Lactobacillus spontaneously growing to high numbers in milk, minced meat, fish or cheese

    Author : Anne-Marie Lindberg; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Food Spoilage; Lactobacillus; Bacillus; Pseudomonas; Aeromonas; Enterobacteriaceae; Livsmedelsteknik;

    Abstract : The spoilage flora of refrigerated raw and pasteurized milk was classified and identified by numerical phenotypic analysis. Isolations of bacteria were made at a defined spoilage stage, when the total aerobic count was 106-107 cfu per ml. The secondary flora of ripened Swedish and Norwegian cheeses was investigated by numerical analysis. READ MORE
