ROSE, ROBERT E. (Massachusetts Department of Public Health, Amherst), AND WARREN LITSKY. Enrichment procedure for use with the membrane filter for isolation and enumeration of fecal streptococci in water. Appl. Microbiol. 13:106-108. 1965.-By the use of PYC enrichment medium, the recovery of fecal streptococci from river water has been increased more than twofold over that of M-Enterococcus Aga...

چکیده: یکی از دوره های مهم تاریخی ایران به لحاظ تأمین استقلال ملی مذهبی و حتی تأثیر آن بر فرهنگ و مذهب ایرانیان، دوره صفویه است. رسمیت دادن و رواج مذهب شیعه توسط شاه اسماعیل اول، یکی از مهمترین اقدامات این دولت محسوب می شود. بنابراین برای اجرای این سیاست، وی منصب صدارت را به عنوان منصبی مذهبی- حکو متی ایجاد کرد .این منصب از دوره ی تیموریان ایجاد شده بود ولی در اواخر این دوره اهمیت بیشتری یافت...
15 صفحه اولEvaluation of Pfizer selective enterococcus and KF media for recovery of fecal streptococci from water by membrane filtration.
Pfizer selective enterococcus (PSE) and KF agars were compared for their recovery of fecal streptococci from sewage effluent on membrane filters. The results showed that PSE agar is highly selective for the enterococci. The tan color resulting from esculin hydrolysis, which was not always visible on the surfaces of the colonies, is not considered a necessary differential characteristic on PSE a...
متن کاملEvaluation of Methods for Detecting Coliforms and Fecal Streptococci in Chlorinated Sewage Effluents
Total coliform (TC), fecal coliform (FC), and fecal streptococcus (FS) recoveries in chlorinated secondary sewage effluents were investigated by the membrane filter (MF) and multiple-tube (most probable number, MPN) methods. The LES two-step MF method was found to be comparable to the MPN procedure for determining TC. The TC detection was 1.5 times greater by the LES two-step technique than tha...
متن کاملFluorogenic selective and differential medium for isolation of fecal streptococci.
Of 44 fluorogenic substrates tested for their ability to differentiate species of fecal streptococci, four yielded species-differentiating reactions. The remaining substrates either yielded uniformly positive, negative, or variable strain-dependent reactions. One substrate, 4-methylumbelliferone-alpha-D-galactoside, was hydrolyzed by Streptococcus bovis and S. faecium and its biotypes. 4-Methyl...
