Abstract

The various fermentation types were represented by different numbers of the strains, e.g. type A by 10, type F by 9, etc. Every strain produced acid within 3 days from D glucose, maltose, esculin, D salicin, D trehalose and levulose. Glycerol was split by every strain, but besides early fermentation late reactions also were observed. All the strains but one split rhamnose within 72 hr. Lactose fermentation was in most cases early positive, but late or irregular fermentation was also observed. None of the strains produced acid from adonitol, dulcitol, raffinose, mannitol, inositol and inulin. The strains, with one or two exceptions, did not split L sorbose, D xylose, D sorbitol, D arabinose and D galactose. The starch splitting, as well as fermentation of sucrose and melecitose by Listeria strains was diverse. There was, however, a close similarity in the case of the two last mentioned carbohydrates. Different results were found in the case of two strains but even these were not contradictory; both strains split melecitose and their sucrose fermenting ability was irregular.
