Purification and genetic determination of bacteriocin production in Enterobacter cloacae.
Enterobacter cloacae (strain DF13) was found to produce a bacteriocin which could be induced by mitomycin C. In the supernatant fluid of the induced culture phagelike particles were found. The bacteriocin was partially purified from induced cultures by ammonium sulfate precipitation and gel-filtration on Sephadex G-150. Ultraviolet-absorbing material was eluted from the Sephadex column in three...
متن کاملProperties of silver sulfadiazine-resistant Enterobacter cloacae.
Two silver sulfadiazine-resistant isolates of Enterobacter cloacae obtained in a burns unit where the drug was in use were studied. These strains were resistant to elevated levels of the drug, and they were cross-resistant to silver benzoate, but not to silver nitrate. Growth of the strains in nutritionally poor defined media sensitized them to the inhibitory action of the drug. Exposure of the...
متن کاملPurification and characterization of two kinds of porins from the Enterobacter cloacae outer membrane.
Two major outer membrane proteins of Enterobacter cloacae 206 were purified and identified as porins by using reconstituted vesicles. The 37-kilodalton porin forms a channel with a radius of 0.6 nm, which prefers positively charged substances to negatively charged ones, whereas the 39- to 40-kilodalton porin forms a larger channel with a radius of 0.8 nm, which has weaker selectivity for electr...
متن کاملPurification and Characterization of cloacae M - 1 ExtracellularAlginate Lyase from Enterobacter
An alginate lyase from the cuiture supernatant of Ehterobacter cloacae M-1 rvas purified by ammonium su]fate precipitation, cation-exchange chromatography (SP-Toyopearl), and gel filtration (Ultrogel AcA44). The final preparation thus obtained showed a single band on SDS-PAGE. The purified enayme had the molecular weight of 38,ooO and 32,OOO by SDS-PAGE and gel filtration, respectiyely. The pl ...
متن کاملBiotyping of Enterobacter cloacae.
A biotyping scheme for Enterobacter cloacae is proposed. Tests with seven substrates that gave reliable, reproducible results with 110 isolates of E cloacae formed the basis of the biotyping scheme which would allow recognition of 128 potential biotypes.
