Characterization of selected strains from Lactobacillus acidophilus and Bifidobacterium bifidum
The presented study aims to characterize Lactobacillus acidophilus DSM 20079 and DSM 20242 and Bifidobacterium bifidum DSM 20082, DSM 20215, DSM 20239 and DSM 20456 strains. Within the framework of the performed investigations, the author evaluated their biochemical properties, resistance to antibiotics, antagonism towards selected pathogens as well as the effect on their survivability of...

Potential commercialization of a microbial medium formulated from industrial food waste
A microbial medium, designated DYSP medium, was produced from food wastes that included defatted soya, clear beer spent yeast, potato solid waste and opaque beer spent grains. Various combinations of the food wastes were used for the media formulations and evaluated for extent of supporting microbial growth of pure cultures. A 3.0 M sodium hydroxide hydrolysis followed by a neutralization process using concentrated...

Studies on immuno-bioactivities of Nyctanthes arbortristis (Oleaceae)
In this study the immunomodulatory potential of an Indian medicinal plant, Nyctanthes arbor-tristis L. (Oleaceae), was investigated. The leaf extracts of N. arbor-tristis is used to treat arthritis, lung injury and some painful conditions such as cancer, chronic fever and rheumatism. An ethanolic extract of N. arbor-tristis (NAEE) was screened in rats for humoral and cell-mediated immune...

In vitro screening of antibacterial activity of aqueous and alcoholic extracts of various Indian plant species against selected pathogens from Enterobacteriaceae
Thirty four medicinal plants, belonging to twenty eight different families, were screened for potential antibacterial activity against six bacterial strains belonging to Enterobacteriaceae, viz.Enterobacter aerogenes ATCC13048, Escherichia coli ATCC25922, Klebsiella pneumoniae NCIM2719, Proteus mirabilis NCIM 2241, Proteus vulgaris NCTC8313,and Salmonella...

Microbial community analysis of drinking water sources from rural areas of Zimbabwe
Traditional methods employing selective, differential and non-selective media were used to isolate and identify different species of bacteria from rural drinking water reservoirs of Mount Darwin district of Zimbabwe. The colony counts from non-selective nutrient agar plates gave an indication of the overall level of bacterial activity from each water sample. Open deep wells, shallow wells and rivers were found to be the...
