  • Abstract
  • Abstract:A wild microorganism, isolated from HTST pasteurized milk processed in a continuous 4 hour operation, was identified as Streptococcus thermophilus, giving greater celular growth in M17 broth, incubated for 6 hours at 45°C. The viable cell count was evaluated in PCA, APT, :MRS e M17, the media M17 and MRS being shown to allow for better growth. (openaire.eu)
  • organism
  • For instance, streptococci use cell-cell communication systems to synchronize competence induction between individuals, allowing them to behave such as a multicellular organism. (frontiersin.org)
  • After storage at 10°C for 6 days, 57.1% of Streptococcus cells remained viable, and organism formed adhesive structures on stainless steel surfaces in 20 hours, these being observed using a scanning eletronic microscope. (openaire.eu)

  • growth
  • In Streptococcus thermophilus , production of ComX is transient and tightly regulated during growth: it is positively regulated by the cell-cell communication system ComRS during the activation phase and negatively regulated during the shut-off phase by unidentified late competence gene(s). (frontiersin.org)
  • Interestingly, most S. thermophilus strains are not or weakly transformable in permissive growth conditions (i.e., chemically defined medium, CDM), suggesting that some players of the ComRS regulatory pathway are limiting. (frontiersin.org)
  • human
  • "Even if most of ​ S. thermophilusstrains appeared to be sensitive to acid pH and bile salts, human studies have established their ability to survive passage through the GI tract and transiently colonize while ingested," ​ they wrote. (nutraingredients-usa.com)
  • analysis
  • Sukhodolets, V. 2007-07-23 00:00:00 Twenty-five Streptococcus thermophilus isolates were analyzed using pulse-field gel electrophoresis (PFGE) and gene restriction profile analysis techniques. (deepdyve.com)
  • The presented medium should be useful for physiological studies of S. thermophilus, and, in combination with the method of analysis of EPS, will allow downscaling of physiological studies and screening for EPSs. (biomedcentral.com)
  • To better understand the defense mechanism of Streptococcus thermophilus against superoxide stress, molecular analysis of 10 menadione-sensitive mutants, obtained by insertional mutagenesis, was undertaken. (univ-lorraine.fr)
