Kim, Ki-han (Wayne State University, Detroit, Mich.). Isolation and properties of a putrescine-degrading mutant of Escherichia coli. J. Bacteriol. 86:320-323. 1963.-A mutant was isolated from Escherchia coli B which can grow on putrescine as the sole source of carbon and nitrogen. This mutant contains a constitutive putrescine alpha-ketoglutarate transaminase and can be induced for the enzymes ...

Precursors of podophyllotoxin were synthesized and screened for their antibacterial activity. The results proved that ethyl-2-(3'-methyl-4'-methoxybenzoyl)-3-(4″ methoxyphenol)-cyclopropane-1-carboxylic acid and Ethyl-2-(3'-methyl-4'-methoxybenzyol-3-1 3″, 4″-dimethoxyphenyl)-cyclopropane-carboxylic acid have significant antibacterial activity against Citrobacter sp., Escherchia coli, Klebsiell...

Fresh flowers of Tagetes erecta L., the flavonoid was isolated by extraction and fractionation with different solvents. It was then identified as patulitrin (10mg/100ml) by various tests. It was then subjected to disc diffusion assay to assess its antibacterial potentials against Alcaligens faecalis, Bacillus cereus, Campylobacter coli, Escherchia coli, Klebsiella pneumoniae, Pseudomonas aerugi...
