Temporal transcription map of the virulent Streptococcus thermophilus bacteriophage Sfi19.
A transcription map was developed for the virulent Streptococcus thermophilus phage Sfi19 on the basis of systematic Northern blot hybridizations. All deduced 5' ends were confirmed by primer extension experiments. Three classes of transcripts were detected based on the different times of appearance. Early transcripts were identified in three genome regions; middle transcripts covered cro-like,...
متن کاملStreptococcus thermophilus.
Streptocus tmophilus, as a species designation (Orla-Jensen, 1919), has included those members of the nonhemolytic streptococci that possess the unusual combination of characteristics of extreme salt sensitivity, nonobligate thermophily, a rigorous fermentative pattern with respect to certain sugars (Sherman, 1937), and, based upon attempts to culture on synthetic media, a notoriety for nutriti...
متن کاملPhysical and genetic chromosomal map of an M type 1 strain of Streptococcus pyogenes.
A physical map of the chromosome of an M type 1 strain of Streptococcus pyogenes was constructed following digestion with three different restriction enzymes, SmaI, SfiI, and SgrAI, and separation and analysis of fragments by pulsed-field gel electrophoresis. The genome size of this strain was estimated to be 1,920 kb. By employing Southern hybridization and PCR analysis, 36 genes were located ...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولGalactokinase activity in Streptococcus thermophilus.
ATP-dependent phosphorylation of [14C]galactose by 11 strains of Streptococcus thermophilus indicated that these organisms possessed the Leloir enzyme, galactokinase (galK). Activities were 10 times higher in fully induced, galactose-fermenting (Gal+) strains than in galactose-nonfermenting (Gal-) strains. Lactose-grown, Gal- cells released free galactose into the medium and were unable to util...
