Snoke, John E. (University of California, Los Angeles), and Neal Cornell. Protoplast lysis and inhibition of growth of Bacillus licheniformis by bacitracin. J. Bacteriol. 89:415-240. 1965.-The growth of Bacillus licheniformis is inhibited by bacitracin, the antibiotic which the organism itself produces. The effect of the antibiotic is confined to the early growth phase of the organism. Bacitrac...

Two active components alpha and beta of micrococcus luteus DNA gyrase, of peptide weights of 115,000 and 97,000, respectively, have been purified. Each individual component exhibits little DNA gyrase activity; the ATP-dependent negative supercoiling of a covalently closed circular DNA duplex is catalyzed by a combination of the two. Covalent closure by Escherichia coli ligase of a circular DNA ...

A new method is described by which separation of staphylococci from micrococci can be achieved in routine laboratory use. The basis of this method is that bacteriolytic activity is produced by staphylococci but not by micrococci.

Biphenyl (BP)-degrading bacteria were identified to degrade various polychlorinated BP (PCB) congers in long-term PCB-contaminated sites. Exploring BP-degrading capability of potentially useful bacteria was performed for enhancing PCB bioremediation. In the present study, the bacterial composition of the PCB-contaminated sediment sample was first investigated. Then extracellular organic matter ...

Phenol in industrial effluent is a major under-reported pollutant of concern to the aquatic ecosystem. In current study, was obtained from Eleme Petrochemical Limited, Rivers State Nigeria. Baseline analyses were conducted ascertain physico-chemical and microbiological parameters. Exogenous bacterial species isolated crude oil polluted Ogoniland. The inoculum standardized using MacFarland appro...

The release of antibiotics (AB) into the environment poses several threats for human health due to potential development of AB-resistant natural bacteria. Even though the use of low-dose antibiotics has been promoted in health care and farming, significant amounts of AB are observed in aquatic environments. Knowledge on the impact of AB on natural bacterial communities is missing both in terms ...
