By use of the staphylolytic enzyme lysostaphin, a method was devised for isolating and purifying highly polymerized deoxyribonucleic acid (DNA) from lysostaphinsusceptible Micrococcaceae. Staphylococcus aureus DNA isolated by this procedure gave an estimated molecular weight of ca. 2 x 10(8) and a residual protein content of 2.3%. The mole percentage of guanine + cytosine (GC) present in the DN...

There is a long history of the microbe-collection experiments at high altitude. Microbes have been collected using balloons, aircraft and meteorological rockets. Spore forming fungi and Bacilli, and Micrococci have been isolated in these experiments. It is not clear how high do microbes go up. If the microbes might have been present even at higher altitudes, the fact would endorse the possibili...

We surveyed 15 different brands of eye shadow on display for customer use in different retail stores for microbial contamination. This was the first reported microbial surveillance of in-use eye shadow display testers in retail establishments. Cultures were obtained at each retail store. Sterile dacron swabs were rolled and rubbed over the entire used surface of each shadow, and each inoculum w...

This study deals with synthesis of methyl cinnamate, butyl cinnamate, and p-methoxy methyl cinnamate and testing of their in vitro antimicrobial activity. Antimicrobial activity was examined towards 29 microorganisms using microdilution method. It is shown that antimicrobial activity of methyl cinnamate and p-methoxy methyl cinnamate was better than that of butyl cinnamate. Sarcina lutea, Bacil...

Three strains o f bacteria reducing (trifluoroacetyl)ferrocene (3) to optically pure (R)-2,2,2trifluoro-l-hydroxyethylferrocene (4) and one bacterial strain reducing 3 to (5 )̂-4 o f moderate optical purity were isolated from sea-water collected at the coastal areas in Ibaraki prefecture o f Japan. The former three strains were identified as Micrococcus lylae, Micrococcus luteus, and D eleya mar...

Dasamularista was prepared as per the national formulary to study the effect of container on the production of alcohol and the presence of microorganisms during the process of fermentation. Citraka (Plumbago rosea Linn.) which was one of the ingredient in the drug and subjected to "Sodhana" was also studied. The Citraka was impoverished by 50% with respect to plumbagin as a result of sodhana-pu...

background: antimicrobial peptides play a role as effectors substances in the immunity of vertebrate and inverte­brate hosts. in the current study, antimicrobial peptide was isolated from the haemolymph of the american cock­roach, periplaneta americana . methods: micrococcus luteus as gram-positive bacteria and escherichia coli as gram-negative bacteria were candi­date for injection. induction ...

BACKGROUND AND PURPOSE The role of opportunistic microorganisms in urethritis in men is controversial. The aim of this study was to determine the changes in urethral microflora in the presence of persistent nonspecific urethritis (PNU) in men by in vitro detection of decomplementary activity (DCA) phenotypes of urethral isolates and comparison of the isolates with those from patients with or wi...
