Effect of quaternary ammonium compounds on bacteria : comparison of sensitive and resistant strains of the same species

Creator:: Albin, Inga Anna Schroder
Abstract:: To determine whether some bacteria are more susceptible than others to quaternary ammonium compounds, the following bacteria were grown on agar slants containing various concentrations of alkyl dimethyl ethyl benzyl ammonium chloride (ADEBAC), and alkyl dimethyl benzyl ammonium chloride (ADBAC): Aerobacter aerogenes 12658, Alcaligenes metalcaligenes, Brevibacterium linens, Chromobacterium lividum, Escherichia...

Mechanisms of lactose metabolism by strains of Streptococcus lactis

Creator:: Walter, Leslie Alva
Abstract:: Rapid acid production by lactic streptococci used in the manufacture of fermented dairy products is essential to the economy of the industry and to the public health of consumers. There remains to developed, however, an adequate laboratory procedure to detect and distinguish between slow and fast strains of these bacteria....

Genetic homology and exchange in lactic acid streptococci

Creator:: Knittel, Martin Dean
Abstract:: The dairy industry relies primarily on consistent acid production by the lactic streptococci for the manufacture of certain cheeses and fermented dairy products. Variation in these cultures due to genetic exchange has not been thoroughly investigated. This study was undertaken to determine if genetic homology exists within the lactic group,...

Control of acid production and β-galactosidase synthesis in lactic streptococci

Creator:: Citti, James Edward
Abstract:: The public health and economic significance of rapid acid production by lactic streptococci in controlled dairy fermentations is well known. However, the fast acid-producing characteristic of these organisms is not stable, and cultures of fast organisms have been shown to contain slow cells. These studies were carried out to characterize...

Metabolism of aroma bacteria as related to diacetyl production

Creator:: Brown, Ruth Elaine
Abstract:: Factors influencing diacetyl production by the aroma bacteria Leuconostoc citrovorum and Streptococcus diacetilactis were investigated. When grown in association with lactic streptococci, L. citrovorum strain 91404 decreased in cell numbers from 10⁸ to 10⁶ over two weeks of daily subculturing in sterile non-fat milk incubated at 21°C. The ability to...

Pathways and enzymes involved in glucose catabolism by lactic streptococci

Creator:: Nandan, Rajiva
Abstract:: The enzymes and pathways involved in the catabolism of glucose by several strains of Streptococcus diacetilactis, Streptococcus cremoris, and Streptococcus lactis, commonly called the lactic streptococci, were studied. The presence of aldolase, triosephosphate isomerase and alcohol dehydrogenase in these organisms provided evidence for the operation of the Embden-Meyerhof-Parnas (EMP) pathway...

Some factors influencing carbon dioxide production by Leuconostoc citrovorum

Creator:: Holmes, Beverly Ann
Abstract:: 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...

Properties of Pseudomonas aeruginosa resistant to quaternary ammonium compound

Creator:: Washam, Clinton Jay
Abstract:: Pseudomonas aeruginosa cells were selected for their ability to grow in the presence of 750 ppm alkyldimethylethylbenzyl ammonium chloride (QAC). These cells were found to retain their resistance to the germicide throughout tri-weekly transfers for 7 months in tryptone glucose yeast extract (TGY) broth containing no QAC. Comparisons of the...
