Manganoxydierende Bakterien. I. Isolierung und Bestimmung einiger Stämme von Manganbakterien

Inter-relationships of MnO2 precipitation, siderophore–Mn(III) complex formation, siderophore degradation, and iron limitation in Mn(II)-oxidizing bacterial cultures

“…The closely related P. putida strains GB-1 (Brouwers et al, 1999;Francis and Tebo, 2001) and MnB1(ATCC 23483) (Schweisfurth, 1973), the two pseudomonads that have been most extensively studied with respect to enzymatic Mn oxidation , were used in this study. The pyoverdine of strain GB-1 (PVD GBÀ1 ; here called PVD for brevity) was purified from the filtered supernate of a 4 L culture in succinate medium (Albrecht-Gary et al, 1994) following standard procedures (Budzikiewicz, 1993).…”

Manganese(III) binding to a pyoverdine siderophore produced by a manganese(II)-oxidizing bacterium

“…Effects of iron on pyoverdine biosynthesis were examined in parallel cultures of Pseudomonas putida strain MnB1 (Schweisfurth, 1973) that were propagated either with or without 10 M FeSO 4 in minimal salts pyruvate (MSP) medium containing (g/L): (NH 4 ) 2 SO 4 , 0.24; MgSO 4 · 7H 2 O, 0.06; CaCl 2 · 2H 2 O, 0.06; KH 2 PO 4 , 0.02; Na 2 HPO 4 , 0.3; and Na pyruvate, 0.8. All subsequent experiments utilized aliquots of a single culture (5 ϫ 10 7 cells/mL) of strain MnB1 which was grown for 18 h at 25°C in MSP medium lacking added Mn or Fe.…”
