Methanolic extract of Elephantopus scaber Linn was investigated for its antibacterial activity against Staphylococcus aureus (NCIM - 2079), Escherichia coli (NCIM-2067), Bacillus subtilis (NCIM-2063), Pseudomonas aeruginosa (NCIM-2036), Proteus vulgaris (NCIM-2027) at 100 μg/disc by using disc diffusion method. The extract showed significant anti bacterial activity and were compared to chloramp...

Penicillin-induced filaments of Proteus vulgaris P 18 had a seemingly unaltered cell envelope. Lysozyme, however, reduced the wall part of these filaments into a three-layered structure and caused transformation into spheroplasts. Although cross walls and membrane septa were absent in the filaments, most of the lysozyme-induced spheroplasts remained attached to each other.

l objective: To test the antimicrobial effectiveness of a silver alginate dressing on opportunistic pathogens, namely meticillin-sensitive Staphylococcus aureus (mSSa) and meticillin-resistant Staphylococcus aureus (mrSa), Klebsiella spp., Enterococcus faecalis, Enterococcus faecium, Pseudomonas aeruginosa, Escherichia coli, Enterobacter sakazakii, Enterobacter cloacae, Serratia marcescens, Chr...

Head-space gas-liquid chromatography and mass spectrometry were used to detect and identify products formed by Proteus vulgaris, P. mirabilis, P. morganii, and P. rettgeri from a defined medium supplemented with either phenylalanine, methionine, valine, leucine, histidine, lysine, ornithine, threonine, asparagine, aspartic acid, or tryptophan. In a detailed study of the products formed by 68 st...

To reduce the surface and interfacial tension of the pollutants in environment, biosurfactants which are produced by the microorganisms such as bacteria, yeast etc. are being applied in large quantity. These compounds are produced extracellularly by the microorganism into the environment and they are applied in different industries such as detergent, cosmetics etc. for different purposes. In th...

The ability of penicillin to induce morphological changes in various strains of Proteus is already well known from the investigations of Qrskov (1947), Lahelle (1948), Levaditi and Henry (1948), Dienes (1949), Tulasne (1949a,b, 1950), Fleming et al. (1950), Freundt (1950), Pulvertaft (1953), and von Prittwitz and Gaffron (1953). The ease with which Proteus produces spherical forms, so-called "l...

It has been found by a number of investigators that cell suspensions and sonic extracts of one species (Proteus vgaris) of the family Enterobacteriaceae contain an enzyme which catalyzes the oxidative deaTnination of most of the i,-amino acids to their corresponding a-keto acids (Bernheim et al., 1935; Uemura, 1942a, b; Uemura, 1944; Stumpf and Green, 1944). Henriksen (1950) utilized this facul...

Streptomyces spp. (Lob18.2b), isolated from soil sample from Everest Base Camp, was obtained from Research Laboratory for Biotechnology and Biochemistry (RLABB). The isolate was found to inhibit Salmonella paratyphi, Salmonella typhi, Proteus mirabilis, Proteus vulgaris, Shigella sonnei, Klebsiella pneumoniae, Klebsiella oxytoca, Escherichia coli, Bacillus subtilis and Staphylococcus aureus on ...
