Optimizing the production of Polyphosphate from Acinetobacter towneri
Inorganic polyphosphates (PolyP) are linear polymers of few to several hundred orthophosphate residues, linked by energy-rich phosphoanhydride bonds. Four isolates had been screened from soil sample. By MALDI-TOF analysis, they were identified as Bacillius cereus, Acinetobacter towneri, B. megaterium and B. cereus. The production of PolyP in four isolates was studied in phosph...
متن کاملAccumulation of polyphosphate in Lactobacillus spp. and its involvement in stress resistance.
Polyphosphate (poly-P) is a polymer of phosphate residues synthesized and in some cases accumulated by microorganisms, where it plays crucial physiological roles such as the participation in the response to nutritional stringencies and environmental stresses. Poly-P metabolism has received little attention in Lactobacillus, a genus of lactic acid bacteria of relevance for food production and he...

only 5 patients had documented seroconversion for CHIKV. However, high titers were found in all but 1 patient (>1,280 in 21 patients and 640 in 2 patients). This patient, who had a titer of 80, was an Italian who had probably not been previously exposed to CHIKV. Thus, the risk for misclassifi cation was low. PCR for early detection of infection was not used because only 3 persons were tested w...

15 صفحه اولPolyphosphate synthetic activity of polyphosphate:AMP phosphotransferase in Acinetobacter johnsonii 210A.
Polyphosphate:AMP phosphotransferase (PAP) has been identified as an enzyme that catalyzes the phosphorylation of AMP with inorganic polyphosphates [poly(P)] as phosphate donors. We found that the purified PAP of Acinetobacter johnsonii 210A has poly(P) synthetic activity. The PAP catalyzes the dephosphorylation of ADP and processively synthesizes poly(P) of 200 to 700 residues. Comparatively l...
