"Bacteriology is such a broad subject that a life-time
spent in its perusal would fail of an entire knowledge of
the subject, so the authors have chosen a field which is certainly one that ought to interest every individual because
it pertains to milk, one of the most important foods...
This study was undertaken to determine the role Leuconostoc
citrovorum may play in carbon dioxide production in milk. The
ability of L. citrovorum strains to produce gas was studied by two
methods. A qualitative method used visual measurement of gas where
an agar plug was forced up the neck of...
Single-strain cultures of Streptococcus cremoris, Streptococcus
lactis, Streptococcus diacetilactis, and Leuconostoc citrovorum produced
little or no acetone and no dimethyl sulfide when grown in milk
culture. These organisms had little or no ability to decarboxylate
antexogenous source of acetoacetic acid nor were they capable of
producing dimethyl sulfide from methyl...
Trypticase-Soy Broth (TSB) was inoculated with Streptococcus
diacetilactis, incubated at 21C for 24 hours and centrifuged to remove
the cells. When the spent TSB was inoculated with Staphylococcus
aureus, it allowed 99.8% less growth than fresh TSB. If the spent
TSB were supplemented with 0.08 μg/ml of niacinamide, this inhibition...
