  1. 1. A thermostable alkaline protease from a new alkaliphilic Nesterenkonia sp

    University dissertation from Department of Biotechnology, Lund University

    Author : Shahrzad Bakhtiar; Lund University.; Lunds universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substrate specificity; crystallization; Biotechnology; Bioteknik; DNA-DNA hybridisation; 16S rDNA analysis; phenotypic characterisation; circular dichroism; differential scanning calorimetry; Nesterenkonia abyssinica; stability; calcium-independent; alkaline protease; alkaliphilic;

    Abstract : This thesis concerns a novel alkaline protease produced by an extremophilic microbial specie, designated as AL20, isolated from a feather sample collected at the shore of the alkaline soda lake Abjata in the Ethiopian Rift Valley. The isolate is a heterotrophic, alkaliphilic, halotolerant gram-positive, strictly aerobic, non-motile, non-spore forming bacterium. READ MORE

  2. 2. Molecular analysis of the oral microbiota of dental diseases

    University dissertation from Umeå : Odontologi

    Abstract : Traditionally, bacterial culture has been used for bacterial detection, allowing study of living microorganisms. Molecular methods are rapid and allow simultaneous identification of numerous species and uncultivated phylotypes. READ MORE

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

    University dissertation from Department of Food Technology, Lund University

    Author : Mei Wang; Lund University.; Lunds universitet.; [2004]
    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

  4. 4. Development of an Ultrasensitive Capacitive DNA-sensor: A promising tool towards microbial diagnostics

    University dissertation from Lund University (Media-Tryck)

    Author : Ally Mahadhy; Lund University.; Lunds universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacitive DNA-sensor; Enterobacteriaceae; mecA gene; Methicillin resistance; automated sequential injection analysis; sandwichhybridization; elevated temperature; polytyramine;

    Abstract : 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.
