Isolation of auxotrophic mutants of Bacillus cereus

Creator:: Keng, Jiun Guang
Abstract:: Bacillus cereus excretes large amounts of penicillinase into growth media during incubation, hence the widely-used penicillin selection technique for isolating biochemical mutants of bacteria is not applicable to this species. Genetic transfer in B. cereus has not been reported; this is partly due to the lack of an effective isolation...

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...

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...

Host range and chemical composition of lactic streptococcal bacteriophages

Creator:: Henning, David Ralph
Abstract:: Comparisons were made of the abilities of Streptococcus lactis, Streptococcus cremoris and Streptococcus diacetilactis bacteriophages to endure various laboratory isolation and storage treatments. Neutralization of Cottage cheese whey containing phages offered no survival advantage over unneutralized samples, refrigeration of neutral and acid whey samples increased the survival of only the...

Studies on mutation and lactose fermentation in lactic streptococci

Creator:: Wagner, Sally Ann
Abstract:: This study involved an investigation of lactic streptococci which had irreversibly lost ability to produce the high levels of acid in milk necessary during the manufacture of certain fermented dairy products. The slow acid producing mutants studied were obtained from a normal acid producing strain by natural selection following induction...

Factors related to resisitance of bacteria to quaternary ammonium germicides

Creator:: Wang, Wei-sheng
Abstract:: This study was carried out to compare the effects of a quaternary ammonium compound (QAC) upon strains of Pseudomonas aeruginosa which were either sensitive or resistant to the germicide. The cationic QAC used was alkyldimethylbenzylammonium chloride. The resistant types were isolated from the sensitive population by selection of mutants which...
