Studies to improve lactic acid bacterial starter cultures

Creator:: Khosravi, Lewa
Abstract:: Three commercial sausage starter cultures were grown in an internal-pH-controlled medium (PHASE 4) and in a soluble phosphate-buffered medium. The cultures were tested by comparing viable counts before and after freezing at -40 C or freeze-drying and subsequent storage for 3 months in the frozen or dried state. Strains varied...

Antimicrobial resistance and plasmid properties of Leuconostoc and group N Streptococcus

Creator:: Orberg, Paulo K.
Abstract:: A method for rapid isolation of plasmid DNA from group N streptococci was developed. Chief advantages of the method were simplicity, the utilization of microliter quantities of reagents, and the obtainment of preparations highly enriched for covalently closed circular plasmid DNA. The method was also applied to over 15 Leuconostoc...

Conjugal transfer of plasmid genes between lactic Streptococcus and Leuconostoc starter bacteria

Creator:: Tsai, Huai-jen
Abstract:: Mutants of Streptococcus lactis 7962 with various combinations of plasmid molecular masses were screened for nisin production. Nisin was produced by both wild type and mutants that contained a 17.5 Md plasmid, which was usually obscured by the chromosomal fragments. No nisin was produced by plasmid-free mutants. Sucrose fermentation and...

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...
