The recent development of biological sensors has extended marine plankton studies from conducting laboratory bench work to in vivo and real-time observations. Flow cytometry (FCM) has shed new light on marine microorganisms since the 1980s through its single-cell approach and robust detection of the smallest cells. FCM records valuable optical prop...

The objective of this work was to test the growth of the freshwater microalga Chlamydopodium fusiforme MACC-430 in diluted piggery wastewater (PWW) for biomass production which is a potential producer of biostimulating and antimicrobial compounds. The productivity and effectiveness in removing nitrogen and phosphorus by the cultures were tested out...

Among cyanobacteria isolated from Northern Adriatic five strains were able to grow on oil refinery wastewater. Based on the sequencing of the internal transcribed spacer (ITS region) and morphological features strains were identified as Synechococcus sp. MK568070, Phormidium lucidum MK568072, Neolyngbia sp. MK568073, Pseudanabaena sp. MK568071 and...

The aim of the study was to explore the possibility of bioremediation of oil refinery wastewaters by the cyanobacterium Synechococcus sp. MK568070, isolated from the Adriatic Sea. The potential of biomass and lipid production was explored upon cultivation on oil refinery wastewater with excess CO2 after the removal of nutrients. The strain grew wel...

In this study, we focus on the interactive dynamics between physico-chemical processes and picoplankton distribution in order to advance our current understanding of the roles of various parameters in regulating picoplankton community structure in highly dynamic marine system such as the South Adriatic Sea. The research was carried out between Octo...

Heterotrophic microorganisms represent the main consumers and mineralisers of the organic matter in the ocean as well as in inland waters. These organisms are in strong interaction with phytoplankton and higher trophic levels and may react quickly to environmental changes. In contrast with phytoplankton, due to the lack of photosynthetic pigments t...

The planktonic diatoms belonging to two genera Chaetoceros and Bacteriastrum, included within the family Chaetocerotaceae, are ecologically important as they represent an important component of the phytoplankton in the coastal regions and are often among bloom-forming taxa. We analysed the chaetocerotacean species composition and abundances in the...

The ecological preferences of different phytoplankton types drive their temporal and spatial distributions, reflecting their dependence on certain temperature ranges, light levels, nutrient availability and other environmental gradients. Hence, some phytoplankton taxa can be used as water mass tracers (biotracers). In order to determine the biotra...

This paper documents the picoplankton community's response to changes in oceanographic conditions in the period between October 2011 and September 2012 at two stations belonging to the South Adriatic Pit (SAP). The recorded data include the community's abundance, composition, prokaryotic production rates and bacterial metabolic capacity. The sampli...

The effect of environmental conditions on bacterial community structures, production and enzymatic activities was studied in north-eastern Adriatic in the late spring of 2009 in waters belonging to the two gyres, the cyclonic (CG) and the anticyclonic (AG) one, and in waters non-affected by presence of the two gyres. The AG and CG were formed in a...

Differentiation of the plankton food web structure was studied during the 2003–2008 period, in situations when the system of the northern Adriatic Sea, one of the most productive area in the Mediterranean, switched from low nutrient to higher nutrient regime. The biomass distribution between autotrophs, bacte-ria, protozoans and metazoans showed th...

The bacterial community in coastal waters of northeastern Adriatic Sea was dominated by SAR11 and Sulfitobacter taxa throughout the year. The seasonal distribution of bacterioplankton taxa showed continual differences between surface (0 m) and bottom (27 m) layers. The surface assemblage was represented by Actinobacteria, Cyanobacteria, Alphaproteo...

This work describes the dynamics of the autotrophic plankton community in Lim Bay in the north-eastern part of the Adriatic Sea from June 2008 to September 2009. There was an evident shift between microphytoplankton and picophytoplankton domination in summer and autumn periods, while nanophytoplankton contributed negligibly. Picophytoplankton do...

The species composition and size-structure of the phytoplankton community in the Boka Kotorska Bay (SE Adriatic Sea) were analysed with respect to abundance and carbon biomass, together with the physico-chemical parameters, with the aim of evaluating the predefined oligo-mesotrophic status of this transitional water ecosystem. Three stations locate...

We present the first insight to the oceanography of the southeastern Adriatic Sea, where coastal water influenced by Albanian rivers comes into contact with the inflowing oligotrophic Eastern Adriatic Current (Ionian Surface Water and Levantine Intermediate Water). A distinct plankton distribution was observed on each side of the shelf break hydrog...

Picoplankton distribution at the boundary zone of the southern Adriatic in May 2009 on a 75 km long shelf-continental slope transect was assessed by combining epifluorescence microscopy, flow cytometry and high-performance liquid chromatography data with hydrographic observations. The picoplankton distribution was greatly influenced by the hydrogra...

We present evidence that transparent exopolymer particles (TEP) accumulate in the northern Adriatic Sea as a result of the intrusion of oligotrophic high-salinity water (OHSW) from the south during summer. Samples were collected in June and July of 2007 in haloclines, and in the layers above and below them, at 2 stations in the region of the highes...

During the 1990-2008 period heterotrophic prokaryotes abundance (HP) in the northern Adriatic showed a substantial decrease after 2003. Before 2003 the HP annual cycle was characterized by minimal values during winter (100-134·107celll-1, on average) and a gradual increase toward summer (up to 212·107celll-1, on average). After 2003 HP was low duri...

The distribution of phytoplankton and its relation to the hydrographic features in the north-eastern Adriatic was investigated in February 2008. The area ofinterest included a thermohaline gradient in the channel situated between the coast and the islands lying parallel to the coast. The gradient is controlledby the influx of oligotrophic karstic r...

The importance of bacterial, phytoplankton and dissolved alkaline phosphatase activity (APA) in the northern Adriatic was investigated during 2006. In surface waters total APA increased from early spring (0.07-0.08 micromol l(-1) h(-1)) to late spring (up to 4.64 micromol l(-1) h(-1)) and remained relatively high during the summer (0.46-0.71 microm...

Flow cytometry was used for the first time to determine the abundance of pico-and nanophototrophic plankton in the northern Adriatic during five cruises, from June to December 2006, along the west-east trophic gradient from the Po River delta (Italy) to Rovinj (Croatia). The firstly recorded occurrences of Prochlorococcus were obtained. Synechococc...
