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....

Some aspects of the mechanism of action of iodophor and other germicides on microorganisms

Creator:: Shikashio, Tommy Kiyoshi
Abstract:: The concentrations of iodophor necessary to reduce the activity of several metabolic enzyme systems 50 percent was used as the basic approach in attempts to elucidate the mechanism of germicidal action of iodine. For comparisons, a chlorine-releasing germicide (Trichlorocide) and a quaternary ammonium compound were also tested. It was found...

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...

Characterization of 16S Ribosomal RNA Probe-Isolated Lactococci from nature for use in Cheddar cheese manufacture

Creator:: Daniels, Brent E.
Abstract:: Strains of Lactococcus lactis ssp. lactis and Lactococcus lactis ssp. cremoris with potential use in the food industry which had been previously isolated from nature using 16S rRNA probes were characterized for unique identifying traits and for attributes important for potential use in cheese manufacture. Strains of Lc. cremoris which...

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...

Development of internally pH-controlled bulk starter media for the propagation of lactic acid bacteria

Creator:: Willrett, Douglas L.
Resource Type:: Dissertation
Full Text:: -acid material content of yeast extract enabled 'slow' acid-producing lactic streptococci to compete

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...
