Abstract
U ovom radu istraživana je indukcija biofiltara s različitim punilima – biokuglice, kamen raspršivač zraka i pergolar. Indukcija je proučavana u dva eksperimenta, jednim s komercijalno dostupnom kulturom bakterija za pročišćavanje vode u akvakulturi i drugim s bakterijama iz kućnog akvarija. Praćene su promjene relevantnih pokazatelja kvalitete vode: saliniteta, temperature, pH i koncentracija otopljenog kisika, nitratnog, nitritnog i amonijakalnog dušika te količine bakterijske biomase. Iako su okolišni faktori bili oko optimuma, tijekom 15 dana nije postignuta učinkovita nitrifikacija pa se preporučuju daljnja istraživanja indukcije biofiltara uz primjenu molekularnih analiza koje će dati uvid u sastav mikrobnih zajednica u sustavu i objasniti njihovu interakciju te njen utjecaj na provedbu biološke filtracije.
Abstract (english)
This paper studies the start-up of biofilters with different carriers – bioballs, air diffusor stone and pergolar. Start-up was studied in two experiments, one with a commercially available bacterial culture for water purification in aquaculture and the other with bacteria from a home aquarium. Indicators of water quality were monitored: salinity, temperature, pH as well as concentrations of dissolved oxygen, nitrate, nitrite, ammonia and the amount of bacterial biomass. Although environmental factors were around optimum, an effective nitrification was not achieved for 15 days, thus it is recommended to further research biofilters start-up with the application of molecular analysis that will provide insight into the composition of microbial communities in the system and explain their interaction and its impact on the performance of biological filtration.
