title: Characterisation and metabolic studies of Saccharomyces cerevisiae and Kluyveromyces fragilis by flow microcalorimetry.
abstract: The use of microcalorimetry in the routine identification of microorganisms is critically discussed and assessed. By use of flow microcalorimetric studies on Saccharomyces cerevisiae and Kluyveromyces fragilis the role of physical parameters and that of oxygen tension are discussed. The conclusion reached is that identification of microorganisms by microcalorimetry and subsequent discussion of metabolic events revealed by the thermogram, except under restrictive conditions, is inappropriate. However flow microcalorimetry, in contrast to batch microcalorimetry which has been used in the published material on microorganism identification, may allow characterization of yeasts suitable for particular industrial processes.
