  2. 1. Ammonia-Oxidising Bacteria in Soil : Studies of diversity and abundance using 16S rRNA gene analysis

    Author : Anna Hermansson; Janet Jansson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nitrification is the process whereby ammonia is oxidised to nitrate. The first step of this process is carried out by the chemoautotrophic, ammonia-oxidising bacteria (AOB), which convert ammonia to nitrite. READ MORE

  4. 2. The importance of maturation factors in 30S ribosomal subunit assembly

    Author : Stefan Nord; Mikael Wikström; Dan Andersson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribosome; 30S; rRNA; RimP; RbfA; C23U; rpsE; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The assembly of the ribosome is a complex process that needs to be highly efficient to support maximum growth. Although the individual subunits of the ribosome can be reconstituted in vitro, such a reaction is inefficient in comparison to the assembly rate in vivo. READ MORE

  5. 3. Characterization of the Intestinal Microbiota by DNA-Based Methods

    Author : Mei Wang; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; bacteriology; virology; Microbiology; Ulcerative colitis; T-RFLP; 16S rRNA; Brachyspira; Microbiota; Bacterial diversity; Bacterial translocation; Translocating bacteria;

    Abstract : The intestinal flora and the bacteria found in the extraintestinal sites were studied in liver injury rats, with or without Lactobacillus plantarum 299v pre-treatment. The dominating intestinal flora and translocating bacteria were typed by RAPD and identified by 16S rDNA sequencing. READ MORE

  6. 4. An Alkaline Active Cyclodextrin Glycosyltransferase from an Alkaliphilic Bacillus agaradhaerens

    Author : Rita Martins; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloning; characterization; purification; 16S rRNA gene analysis; screening; alkaliphiles; soda lakes; Bacillus agaradhaerens; cyclodextrins; cyclodextrin glycosyltransferase; alpha-amylase family; sequencing; immobilization; Biotechnology; Bioteknik;

    Abstract : Soda lakes represent the most stable naturally-occurring alkaline environments on Earth and harbour a diverse population of alkaliphiles. Alkaliphilic microorganisms have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values. READ MORE

  7. 5. When bioelectrochemical systems meet extremophiles, possibilities and challenges

    Author : Gaofeng Ni; Mark Dopson; Bert Hamelers; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidophiles; psychrophiles; haloalkaliphiles; bioelectrochemical systems; microbial sulfur metabolism; 16S rRNA gene amplicon sequencing; metagenomics; metatranscriptomics; Mikrobiologi; Microbiology;

    Abstract : Extremophiles are microorganisms live and thrive in extreme environments that are harsh and hostile to most forms of life on earth (e.g. low pH, low temperature, high pH and high salinity). They have developed strategies to obtain nutrients and conserve energy to sustain life under these adverse conditions. READ MORE
