the performance of selective media ltb, (leauryl tryptose broth), mmgm (minerals modified glutamate medium), bgbb (brilliant green bile broth), for the detection of e.coli in water in water, were compared and the following result were obtained: the mmgm found to be unsuitable as confirmatory medium for the detection of e.coli at 44 c, due to the occurrence of an unacceptable number of the false...

Culturing is an indispensable technique in microbiological research, and culturing with selective media has played a crucial role in the detection of pathogenic microorganisms and the isolation of commercially useful microorganisms from environmental samples. Although numerous selective media have been developed in empirical studies, unintended microorganisms often grow on such media probably d...

A selective enrichment procedure, using two new selective media, was developed to isolate Pasteurella multocida from wild birds and environmental samples. These media were developed by testing 15 selective agents with six isolates of P. multocida from wild avian origin and seven other bacteria representing genera frequently found in environmental and avian samples. The resulting media--Pasteure...

in this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. in this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were reduced to their corresponding reduce...

Using fresh clinical material, a comparison of a number of anaerobic selective media was made. For Gram-negative anaerobes nalidixic acid tween agar (NAT), neomycin agar (NA), and neomycin-vancomycin agar (NVA) all performed equally well. Kanamycin-containing media were more inhibitory to all Gram-negative anaerobes other than Bacteroides fragilis and B. melaninogenicus. When the recovery of Gr...

Background Recently, there has been a fast growth in the use of different kind of media especially in adolescents. Media literacy education is supported by numerous national organizations and institute as a potential tool to decrease negative media effects and to increase desirable use of media. However, there are little documents about their effects. This study was conducted to investigate the...

Concerns about selective exposure to partisan information have become a mainstay for scholars of political communication in the changing media environment. This study draws on a survey of a unique population—readers of political blogs—to explore the relationship between perceptions of mainstream media bias (as hostile media perception) and selective exposure to media sources that provide like-m...
