Lipids of Streptococcus dysgalactiae1

Patricia MacLeod and Alexander Miller, III

Department of Animal Industries, University of Connecticut, Storrs

ABSTRACT

The free lipids extracted from the bovine pathogen Streptococcus dysgalactiae when fractionated into phospholipids, di-and triglycerides, and free fatty acids yielded the following mean percentages: 52.4, 14.0, 8.6, and 25.0, respectively. The total free lipid extracted from S. dysgalactiae was 7.2% of dry cellular weight. The triglyceride fraction contained higher percentages of hexadecenoic, octadecanoic, and octadecenoic acids, but less lactobacillic acid (<1.0%) than found in any of the other lipid fractions, i.e., phospholipids, diglycerides, or free fatty acids.
