Abstract
Cilj ovog rada je bio istražiti i usporediti kako fosfat-akumulirajuća bakterija Acinetobacter junii preživljava nepovoljne vrijednosti pH u planktonskoj formi (slobodne stanice) i imobilizirana na mineralni nosač, u ovom slučaju prirodni zeolitni tuf, (biočestice), te kako to utječe na njenu sposobnost uklanjanja fosfata iz sintetske otpadne vode. Imobilizirane bakterije su bile otpornije na nepovoljne vrijednosti pH od planktonskih, a njihova stopa umnožavanja je bila značajno veća. Metaboličku aktivnost su zadržale i planktonske i imobilizirane bakterije, no postotak uklonjenog fosfata je bio veći u slučaju biočestica. Rezultati pokazuju da je prirodni zeolitni tuf obečavajući nosač fosfat-akumulirajućih bakterija u svrhu korištenja u postrojenjima za pročišćavanje otpadnih voda.
Abstract (english)
The aim of this study was to determine and compare how phosphate-accumulating bacterium Acinetobacter junii survives unfavorable pH levels in planktonic form (free cells) and immobilised on a mineral carrier, in this case natural zeolitic tuff, (biosolids), and also how this affects the ability to remove phosphate from synthetic wastewater. Immobilised bacteria were better at withstanding unfavorable pH levels than planktonic, and their reproduction rates were signifcantly higher. Both planktonic and immobilised bacteria remaind metabolically active, but percentage of removed phosphate was higher for biosolids. Results show that natural zeolitic tuff is a promising carrier for phosphate accumulating bacteria to be used in wastewater treatment plants.
