A novel library-independent approach based on high-throughput cultivation in Bioscreen and fingerprinting by FTIR spectroscopy for microbial source tracking in food industry

Shapaval, Volha; Møretrø, Trond; Åsli, Anette Wold; Suso, Henri-Pierre; Schmitt, J; Lillehaug, D.; Kohler, Achim (Journal article; Peer reviewed, 2017)

Microbiological source tracking (MST) for food industry is a rapid growing area of research and technology development. In this paper, a new library-independent approach for MST is presented. It is based on a high-throughput ...

An automated approach for fringe frequency estimation and removal in infrared spectroscopy and hyperspectral imaging of biological samples

Solheim, Johanne Heitmann; Borondics, Ferenc; Zimmermann, Boris; Sandt, Christophe; Muthreich, Florian; Kohler, Achim (Peer reviewed; Journal article, 2021)

In infrared spectroscopy of thin film samples, interference introduces distortions in spectra, commonly referred to as fringes. Fringes may alter absorbance peak ratios, which hampers the spectral analysis. We have previously ...

An optimized algorithm for separating scattering and chemical absorption in biomedical infrared spectroscopy and imaging

Solheim, Johanne Heitmann (Master thesis, 2017)

Infrarødspektroskopi av biologiske prøver har blitt utviklet til et lovende verktøy for ikke-destruktiv biokjemisk analyse gjennom de siste tiårene. Infrarøde absorbansspektre representerer molekylære fingeravtrykk. ...
