Microbiological Analysis of Water in Rijeka Harbour and Mouth of Rječina

Rječina, Mrtvi kanal i Riječka luka su bogati mikroorganizmima, kako autohtonim, tako i alohtonim vrstama. Među autohtonim vrstama, koje nastanjuju morska i vodena staništa, se nalaze heterotrofne bakterije, heterotrofni nanoflagelati i cijanobakterije, dok se od alohtonih vrsta u takvim sredinama nalaze fekalni koliformi te fekalni streptokoki. Slatke vode obogaćene nutrijentima su dovele fekalne koliforme i fekalne streptokoke u vodeni sustav te su također pogodovale rastu heterotrofnih bakterija i heterotrofnh nanoflagelata, dok je njihov utjecaj na cijanobakterije negativan.Rječina, the Dead Channel, and Rijeka harbour are rich in microorganisms, both indigenous and alien species. Among indigenous species that inhabit marine and aquatic habitats, are heterotrophic bacteria, heterotrophic nanoflagellates and cyanobacteria, while the alien species in such environments are fecal coliforms and fecal streptococci. Freshwater enriched with nutrients and organic material have brought fecal coliforms and fecal streptococci into the aquatic ecosystem and also favor the growth of heterotrophic bacteria and heterotrophic nanoflagellates, while their effect on cyanobacteria is negative
