All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Growth and enterotoxin production by Staphylococcus aureus strains, in the presence of different starter [2:1 (V/V) blend of AM₂:ML₈ strains of Streptococcus lactis] levels was investigated. Sterile, 10 per cent non-fat dry milk was inoculated with S. aureus strains capable of producing all types of enterotoxins, and reduced levels of starters; and was incubated at 32 C for 24 hours. The pH and S. aureus population were determined at 2 hour intervals until 8 hours and at 24 hours. The inhibitory response of lactic streptococci was studied by spot-tests on a lawn of S. aureus strains. …
