Preparation of magnetic iron minerals using sulphate-reducing bacteria
Języki publikacji
Abstrakty
Zastosowanie metabolizmu bakterii redukujących siarczany jest jedną z metod przygotowania siarczków. Jest to metoda biologiczno-chemiczna bazująca na zdolności bakterii do redukcji siarczanów do siarkowodoru, który łączy się z kationami żelaza (II) tworząc nierozpuszczalne osady - siarczki żelaza. W pewnych warunkach wzrostu bakteryjnego biogeniczne siarczki żelaza mogą posiadać cechy magnetyczne. Celem pracy jest zbadanie właściwości magnetycznych i składu biogenicznych siarczków żelaza zsyntezowanych w kulturach bakterii redukujących siarczany w warunkach laboratoryjnych.
Using the sulphate-reducing bacteria metabolism is one of the methods of iron sulphides preparation. It is a biologicchemical method based on the ability of these bacteria to reduce sulphates to hydrogen sulphide, which binds with ferrous cations to form insoluble precipitates - iron sulphides. Under certain bacterial growth conditions biogenic iron sulphides can be magnetic. The target of this work was to study the magnetic properties and composition of biogenic iron sulphides synthesized in cultures of sulphatereducing bacteria under specific laboratory conditions and modified growth media.
