The presence of two sets (rbcL1-rbcS1 and rbcL2-rbcS2) of rbc operons has been demonstrated in Thiobacillus ferrooxidans Fe1 (T. Kusano, T. Takeshima, C. Inoue, and K. Sugawara, J. Bacteriol. 173:7313-7323, 1991). A possible regulatory gene, rbcR, 930 bp long and possibly translated into a 309-amino-acid protein, was found upstream from the rbcL1 gene as a single copy. The gene is located diver...

Alcaligenes latus has been known to produce poly(3-hydroxybutyrate) (PHB) in a growth-associated manner even under nutrient-sufficient conditions. However, the PHB content obtained by fed-batch culture was always low, at ca. 50%, which makes the recovery process inefficient. In this study, the effect of applying nitrogen limitation on the production of PHB by A. latus was examined. In flask and...

A long chain saturated fatty aldehyde is required for maximal light emission in the bioluminescent reaction catalyzed by the enzyme, bacterial luciferase, purified from extracts of Achromobatter &ch.t&. Since the discovery of this requirement by Strehler and Cormier (1, 2), very little has been learned about either the chemical role of aldehyde in the reaction or the nature of the presumed natu...

A 29-year-old woman was admitted to our hospital with complaints of headache, dizziness and nausea. There was a history of spina bifida and placement of ventriculoperitoneal (VP) shunt in early childhood. One month prior to the current admission there was replacement of a VP shunt with a new system because of a mechanical malfunction. At that time there were no clinical signs of infection and c...

Employing floating treatment wetlands (FTWs) and constructed (CWs) is one of the most eco-friendly strategies for bioremediation water contaminants. Here, efficiency FTWs CWs was compared degradation phenanthrene-contaminated first time. The were established by vegetated Phragmites australis in phenanthrene (1000 mg L−1)-contaminated water. Both augmented with a bacterial consortium four strain...

Loss of microbial diversity in conjunction with chronic Pseudomonas aeruginosa colonisation is strongly correlated progressing lung injury cystic fibrosis. The persistence can be explained by mechanisms such as extensive antibiotic resistances and a high capacity to form biofilm. Another factor its ability exert antagonism against other bacteria, e.g. Staphylococcus aureus. In this study, we ar...
