During the period from 19 to 30 August 2017 Danijela Šantić and Ana Vrdoljak stayed in Třeboň (Czech Republic) for participation in the 10th International GAP Meeting (The Group for Aquatic Primary Productivity). They were part of the WG1 working group, which aimed to establish the relationship between algae and bacterial populations in the Římov artificial lake in different environmental conditions.

The International Group for Marine Ecological Time Series (IGMETS) of UNESCO, as a result of synergistic activities of the Ocean Carbon and Biogeochemistry Program (OCB), the International Ocean Carbon Coordination Project (IOCCP), and the International Council for the Exploration of the Sea (ICES), identified and compiled the metadata from a large number of ship-based biogeochemical and ecological ocean time‐series that are currently conducting regular measurements. IGMETS analyzed over 340 open ocean and coastal datasets, ranging in duration from five years to greater than 50 years. Their locations are displayed in a world map (Discover Ocean Time Series, http://igmets.net/discover) and in the IGMETS information database (http://igmets.net/metabase). These cross‐time‐series analyses yielded important insights on climate trends occurring both on a global and regional scale. MICROGLOB group participated in this Project with two time-series datasets in the Adriatic Sea (Kaštela Bay and Stončica).
Dilution technique is used to estimate instantaneous growth rates of heterotrophic bacteria and autotrophic picoplankton (Prochlorococcus, Synechococcus) as well as their mortality rates caused by heterotrophic nanoflagellate (HNF) and ciliate grazing, and viral lysis.
During May asst. prof. Marin Ordulj form University Department of Marine Studies, University of Split visited prof. Peduzzi form the Department of Bio-Oceanography and Limnology, University of Vienna who is well established expert on the subject of marine and aquatic viruses. The goal of the visit was to widen the undergoing research regarding marine viruses in the MICRGLOB project and establish cooperation between IOF’s Laboratory of Microbiology and LIMBO department.
Laboratorij za mikrobiologiju predstavio se temom „SLIKANJE BAKTERIJAMA“. Nasađivanjem na hranjivu podlogu bakterije se može natjerati da svojim rastom stvaraju slike. Za srca na slici lijevo zaslužna je bakterija Escherichia coli i spretne ruke znanstvenika.
Aerobic anoxygenic phototrophs (AAPs) are photoheterotrophic bacteria that require organic substrates for their metabolism and growth, but can derive a portion of their energy requirements harvesting light using bacteriochlorophyll a (BChl a). On the figure, the red dots present mainly AAP bacteria, blue dots are heterotrophs and the green ones are mainly cyanobacteria. AAP bacteria are actively growing part of the microbial community and therefore may play a much more important role in the recycling of organic matter in the ocean than what their abundances alone would predict.
This book provides an overview of scientific activities of the scientists from Laboratory for Marine Microbiology (Institute of Oceanography and Fisheries in Split, Croatia) and collaborators during the last 15 years, which are presented through the number of case studies performed in different marine habitats of the Adriatic Sea, from the open sea, through the coastal areas, channel waters, enclosed bays, river estuaries, to some special extreme habitats. The main topics of the book are: (1) Microbial community structure which provides an overview of the main components of the microbial community; (2) Microbial food web which is focused on the functional aspect of microbial communities, which includes studying the interactions and the carbon flux through the microbial food web; (3) Extreme habitats which presents the research of microbial communities in the two extreme habitats anchialine caves and eutrophic meromictic saline lake; and (4) the final chapter which is devoted to microbial food web as an indicator of marine environment status in the perspective of Marine Strategy Framework Directive, as one of the most important legal documents of the European Community in the field of marine ecosystems protection.
Thanks to ERASMUS+ fellowship our PhD student Ana Vrdoljak spent three months in České Budějovice, Czech Republic, on the University of South Bohemia. Namely, she did extraction of DNA from microbial samples and amplified 18S and 16S rRNA genes of protists and bacteria using PCR. Also, she did clone libraries and sequence analysis of these products in order to make phylogenetic tree reconstruction. I learned how to process CARD FISH and how to design probes for FISH. This was a very valuable experience for her because she got an opportunity to work in a very dynamic environment with excellent scientists.
Under the supervision of Dr Michal Koblížek we have visited the Department of phototrophic microorganisms of the Czech Republic. During our visit we participated in the field experiment in order to establish a new methodology for the determination of Aerobic Anoxygenic Phototrophs (AAP) in marine environment. We also gained a new knowledge about the molecular techniques such as fluorescence in situ hybridization (FISH) and catalysed reported deposition–fluorescence in situ hybridization (CARD FISH).
Microbial communities play an important role in marine ecosystems through their large contribution to carbon production (up to 90%); assimilation of dissolved organic matter, to sustain their metabolism and produce new biomass; and through the transformation of inorganic compounds into forms suitable for primary producers. This manual was conceived as a guide that provides an overview of quantitative methods that can be used in the analysis of various features of communities, including microbial communities, instructions for using these methods, and gives a theoretical bases of the aforementioned methods, in order to understand which methods are appropriate in particular situation and what are their actual achievements in explaining ecological processes.
