The inhibitory action of sodium azide (NaN8) on the growth of bacteria was first reported by Schattenfroh (1896). Apparently no further work of this nature was published until 1937. In the past few years several contributions have appeared dealing with the effects of NaN3 on microorganisms, but, so far as the writers can determine, these studies have not included the filamentous fungi. A famili...

The phytochemical screening, and in vitro antifungal activity of the inflorescence, leaf, stem rhizome crude extracts Costus lucanusianus J. Braun & K. Schum at concentrations 12.5-100 µg/mL were determined against 4 fungal strains; Penicillium notatum, Candida albicans, Aspergillus niger Rhizopus stolonifer by Agar well diffusion method. Secondary metabolites accountable for observed are s...

The utilization of plant materials as alternative therapies to control pathogenic bacteria has recently attracted. effect the fresh seed, freeze-dried leaf and using ethanol aqueous extracts was tested on some organisms standard laboratory procedures. used were Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Salmonella typhi, Klebsella pneumonia oryzae, while fungi Trichoderma harzi...

By using meterological rockets fitted with specially designed analyzers, samples for microbiological investigation have been taken. The analyzer design prevented extraneous microorganisms from penetrating into the analyzer. Before being used, the analyzers were sterilized with high gamma-ray doses. For the first time microorganisms have been detected in the mesosphere at an altitude of 48 to 77...

The antimicrobial activity of the acetone, chloroform, diethyl ether, methanol, and petroleum ether extracts of the lichen Parmelia sulcata and its salazinic acid constituent have been screened against twenty eight food-borne bacteria and fungi. All of the extracts with the exception of the petroleum ether extract showed antimicrobial activity against Aeromonas hydrophila, Bacillus cereus, Baci...
