Effect of phosphorus constituents on the growth of Pseudomonas fluorescens in media supplemented with potassium oxalatoberyllate

Effect of phosphorus constituents on the growth of Pseudomonas fluorescens in media supplemented with potassium oxalatoberyllate. MacCordick, John (Lab. Modeles Inform. Appl. Synth., CNRS, Strasbourg, Fr.). C. R. Hebd. Seances Acad. Sci., Ser. D, 285(16), 1537-40 (French) 1977. CODEN: CHDDAT. ISSN: 0567-655X. DOCUMENT TYPE: Journal CA Section: 3 (Biochemical Interactions) Section cross-reference(s): 4 The inhibitory effect of K oxalatoberyllate [14263-61-7] (100 mM) on the growth of P. fluorescens was almost completely prevented by Na b-glycerophosphate [819-83-0] when the latter was added to the medium at 590 mg P/L. Inactivation of Be was due to the formation of a Be glycerophosphate complex. KH2PO4 also counteracted the effect of Be on P. fluorescens, but its action was less pronounced than that of glycerophosphate and was attributed to elimination of Be by pptn.

Formation of zinc phosphate layers on surfaces of iron, steel, zinc and their alloys

Formation of zinc phosphate layers on surfaces of iron, steel, zinc and their alloys. Benazet Lluis, Jose; Garcia Arteaga, Pablo (Spain ). Span. ES 416332 16 Feb 1976,15 pp. (Spanish). (Spain). CODEN: SPXXAD. CLASS: IC: C23C. APPLICATION: ES 19730627. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) Corrosion-resistance and paint coating properties were improved with an addn. of salts of org. phosphate complexes to a Zn phosphate bath. The coating substrate is rinsed and then immersed in a chromate-phosphate bath. A bath conc. contg. Zn 1.8-1.9, P2O5 4.5-4.6, and NO3 1.5-1.6 mol/L was dild. to 4.25% to obtain an immersion bath. 5 Mmols of org. phosphate/L bath was used such as HOCH2CHMeOPO3Na2 [39683-77-7], (HOCH2)2CHOPO3Na2 [819-83-0], HOCH2CH(OH)CH(CH2OH)OPO3Na2 [61503-95-5], HO(CH2)2CH(CH2OH)CH(CH2OH)OPO3Na2 [61503-96-6] or the phosphate derivs. of pentaerythritol, ribose, or mannitol.
