DNA gyrase from the albicidin producer Xanthomonas albilineans has multiple-antibiotic-resistance and unusual enzymatic properties.
The sugarcane pathogen Xanthomonas albilineans produces a family of antibiotics and phytotoxins termed albicidins, which inhibit plant and bacterial DNA gyrase supercoiling activity, with a 50% inhibitory concentration (50 nM) comparable to those of coumarins and quinolones. Here we show that X. albilineans has an unusual, antibiotic-resistant DNA gyrase. The X. albilineans gyrA and gyrB genes ...
متن کاملMetabolism of Alcaligenes denitrificans in biofilm vs planktonic cells.
AIMS To compare the effect of phosphorous concentration (200 mg P l(-1) and 20 mg P l(-1)) on the denitrifying efficiency of Alcaligenes denitrificans when in the form of planktonic cells or in the form of a biofilm, and to select the most adequate C/N ratio. METHODS AND RESULTS Two types of assays were carried out: with planktonic cells and with cells in biofilm form. Anoxic bottles with the...

متن کاملAntibiotic Resistance Pattern and Frequency of mecA Gene in Staphylococcus aureus Isolated from Shohada Hospital, Tabriz
Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) can cause serious and life-threatening hospital- and community-acquired infections. Colonized and infected patients represent the most important reservoir of MRSA in health care facilities. Therefore, in this study, MRSA isolates collected from Shohada Hospital in Tabriz were evaluated for the frequency of mecA gene and their anti...
