Plasmid transduction in Streptococcus thermophilus

Molecular and General Genetics MGG, 1988
Streptococcus thermophilus is a common dairy starter for which very few genetic exchange systems have been described. Here we report plasmid transduction by phi 17 alpha and phi 56 alpha, two virulent phages of industrial yogurt starter strains. Several replicons could be transduced, independently of their size, with efficiencies which are high enough ...

Ectopic Spacer Acquisition in Streptococcus thermophilus CRISPR3 Array

Microorganisms, 2021
Streptococcus thermophilus relies heavily on two type II-A CRISPR-Cas systems, CRISPR1 and CRISPR3, to resist siphophage infections. One hallmark of these systems is the integration of a new spacer at the 5′ end of the CRISPR arrays following phage ...

UDP-N-Acetylglucosamine 4-Epimerase Activity Indicates the Presence of N-Acetylgalactosamine in Exopolysaccharides of Streptococcus thermophilus Strains [PDF]

, 2001
The monomer composition of the exopolysaccharides (EPS) produced by Streptococcus thermophilus LY03 and S. thermophilus Sfi20 were evaluated by high-pressure liquid chromatography with amperometric detection and nuclear magnetic resonance spectroscopy ...

Activation of silent gal genes in the lac-gal regulon of Streptococcus thermophilus [PDF]

, 2001
Streptococcus thermophilus strain CNRZ 302 is unable to ferment galactose, neither that generated intracellularly by lactose hydrolysis nor the free sugar.

Molecular diagnostic of streptococcus thermophilus [PDF]

, 2021
Streptococcus thermophilus is one of the most important lactic acid bacteria in the dairy industry. Despite the wide use of Streptococcus thermophilus in the industry, data on the phenotypic and genetic strain variations within the species are still ...

Streptococcus thermophilus JM905—Strain Carbon Source Utilization and Its Fermented Milk Metabolic Profile at Different Fermentation Stages

Foods, 2023
The metabolic utilization of different carbon sources by Streptococcus thermophilus JM905(S. thermophilus JM905) was determined using a high-throughput microbial phenotyping system, and changes in fermentation characteristics of S.

Identification and characterization of a moonlighting protein-enolase for surface display in Streptococcus thermophilus

Microbial Cell Factories, 2020
Background Streptococcus thermophilus is an important food starter and receiving more attention to serve as cell factories for production of high-valued metabolites. However, the low yields of intracellular or extracellular expression of biotechnological

Galactose transport in Streptococcus thermophilus [PDF]

Applied and Environmental Microbiology, 1985
Although Streptococcus thermophilus accumulated [14C]lactose in the absence of an endogenous energy source, galactose-fermenting (Gal+) cells were unable to accumulate [14C]galactose unless an additional energy source was added to the test system. Both Gal+ and galactose-nonfermenting (Gal-) strains transported galactose when preincubated with sucrose.

Structure Characterization of Polysaccharide from Chinese Yam (Dioscorea opposite Thunb.) and Its Growth-Promoting Effects on Streptococcus thermophilus

Foods, 2021
To clarify the mechanisms underlying the growth-promoting effects of yam polysaccharide on Streptococcus thermophilus (S. thermophilus), the yam polysaccharide was extracted using a deep eutectic solvents (DESs) method and separated into four fractions ...
