Abstract

Ubrzana industrijalizacija i urbanizacija prouzrokovale su značajno narušavanje kvalitete okoliša. Uviđajući to, društvo i znanstvenici sve više pažnje posvećuju pokušajima revitalizacije narušenih sastavnica okoliša. Zbog dugotrajnosti i premale učinkovitosti tradicionalnih postupaka za remedijaciju okoliša, svakodnevno se istražuju potencijalni novi i održiviji postupci. Bioremedijacija je postupak smanjenja, detoksikacije ili potpunog uklanjanja onečišćenja iz okoliša upotrebom metabolizma mikroorganizama. Mora i oceani su potencijalni izvori novih mikroorganizama za primjenu u bioremedijaciji i vrlo su malo istraživani. U ovom je radu istraživan je potencijal morskih mikroorganizama za primjenu u bioremedijaciji. Provedena je kvalitativna i kvantitativna analiza autohtone zajednice mikroorganizama u uzorku morske vode iz Jadranskog mora. Mikrobiološke kulture su uzgajane na različitim hranjivim podlogama i temperaturnim uvjetima, te se pratilo njihovo održavanje bez i uz dodatak hranjivih tvari. Nakon izolacije identificirane su bakterijske kulture iz rodova Oceanobacillus, Exiguobacterium i Rhodococcus.

Abstract (english)

Accelerated industrialisation and urbanisation have led to a considerable deterioration in the quality of the environment. Aware of this fact, society and scientists are devoting more and more attention to attempts to revitalise damaged components of the environment. Due to the long duration and inadequate efficiency of conventional environmental remediation technologies, new and more sustainable methods are being researched on a daily basis. Bioremediation is the process of reducing, detoxifying or completely removing environmental pollution through the metabolism of microorganisms. Seas and oceans are potential sources of new microorganisms that can be used in bioremediation and have been very little researched so far. In this work, the potential of marine microorganisms for use in bioremediation was investigated. A qualitative and quantitative analysis of the autochthonous community of microorganisms in a seawater sample from the Adriatic Sea was carried out. The microbiological cultures were grown on different culture media and under different temperature conditions, and their maintenance was monitored without and with the addition of nutrients. After isolation, bacterial cultures from the genera Oceanobacillus, Exiguobacterium and Rhodococcus were identified.
