Anaerobic degradation of nitrilotriacetate (NTA) in a denitrifying bacterium: purification and characterization of the NTA dehydrogenase-nitrate reductase enzyme complex

OPINION ON Trisodium nitrilotriacetate (NTA)

Uptake of iron and nitrilotriacetate (NTA) in rat liver and the toxic effect of Fe-NTA.

A previous study has shown that a single injection of ferric nitrilotriacetate (Fe-NTA) produces hepatic parenchymal iron loading in rats. The present paper reports on iron uptake by rat liver and iron toxicity in the liver after a single injection of Fe-NTA (7.5 mg Fe/kg B.W.). Iron uptake was examined with 59Fe-NTA and Fe-[14C]-NTA. Thirty percent of the injected 59Fe was incorporated in the ...

Consider a 2NTA A, and let k be the magnitude of the largest constant appearing in a clock constraint in the transitions of A. Given a timed word w = (;) of length n, deene R w to be the set comprising of i + c and (i + j + c)=2 for 1 i; j n ...

Biodegradation of nitrilotriacetic acid (NTA) and ferric-NTA complex by aerobic microbial granules.

Development of mixed-culture microbial granules under aerobic conditions in a sequencing batch reactor (SBR), capable of completely degrading a recalcitrant metal chelating agent is reported. In laboratory-scale reactor studies, the microbial granules degraded 2mM of free nitrilotriacetic acid (NTA) and Fe(III)-NTA completely in 14 and 40 h, respectively. Free NTA was degraded at a specific rat...

extraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds

سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
