Properties and distribution of a metallo-β-lactamase (ALI-1) from the fish pathogen Aliivibrio salmonicida LFI1238
Kristiansen, Anders; Grgic, Miriam; Altermark, Bjørn; Leiros, Ingar (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)Objectives. To characterize the chromosome-encoded metallo-β-lactamase (MBL) from the psychrophilic, marine fish-pathogenic bacterium Aliivibrio salmonicida LFI1238 and check for the presence of the gene in other Aliivibrio isolates both connected to the fish-farming industry and from the environment. Methods. The MBL gene was cloned and intracellularly expressed in Escherichia coli. Kinetic ... -
Purification and characterization of a salt tolerant metallo-beta-lactamase from Aliivibrio salmonicida
Kristiansen, Anders (Master thesis; Mastergradsoppgave, 2011-07)Beta-lactamases are enzymes that inactivate beta-lactam antibiotics by hydrolyzing the amide bond that exists in the beta-lactam ring, disrupting the ring structure and make the antibiotics nonfunctional against bacteria. Metallo-beta-lactamases (MBLs) are a group of beta-lactamases which needs metal ions bound to its active site in order to function and are an important factor in many bacteria in ... -
Time and temperature control of a camera
Kristiansen, Anders (Master thesis; Mastergradsoppgave, 2010-07-13)In scientific experiments there are an increasing usage of cameras, along with other instruments, to observe parameters of physical processes. In this thesis, we will discuss how a microcontroller (ATMEL ATmega 324 PA) can be used to control the operation temperature in a camera. It will be discussed why this control of temperature can be useful for the quality of the pictures. Since this thesis is ...
