Abstract

Koreivienė J., Kasperovičienė J., Savadova K., Karosienė J., Vitonytė I., 2016: Collection of pure cultures of algae and cyanobacteria for research, teaching and biotechnological applications (Nature Research Centre, Lithuania) [Dumblių ir melsvabakterių kolekcija mokslui, mokymui ir biotechnologiniams tyrimams (Gamtos tyrimų centras, Lietuva)]. -Bot. Lith., 22(1): 87-92.The collection of pure cultures of algae and cyanobacteria deposited at the Nature Research Centre is a unique and diverse culture collection in Lithuania. It was initiated on the basis of a few national projects in 2010 as an outcome of ecological and molecular studies on invasive and harmful bloom-forming algae and cyanobacteria. To date, the collection holds more than 500 strains, which belong to ten classes, over 70 genera and 140 species. Strains were isolated from Lithuanian freshwaters and the Curonian Lagoon. The collection serves for various research topics including species interactions, molecular analysis, biotechnology (remediation of wastewaters, cell wall disruption, high-and low-value bioproducts), as well as for teaching purposes. The European Union has recently adopted an ambitious strategy for the development of bioeconomy and advised to cover the growing demand of the food, energy and industrial sectors from the innovative use of sustainable biological resources (Enzing et al., 2014). In this approach, algae have great importance for the future application in industry and other fields. Algal culture collections are irreplaceable and unique source providing consistency and standardized quality material for many types of investigations such as comparative taxonomic, physiological, ecotoxicological and ex situ ecological studies (Day et al., 2004). Ecological investigations of algal and cyanobacteria community in the ecosystems nowadays are often combined with the experimental studies in which pure cultures are included. Also, the development of sustainable and friendly technologies that involve new trends of applied sciences has started in the last two decades, therefore, algae and cyanobacteria serve as natural ecological resource for human being. Based on cultured species, a number of environmental and biotechnological studies that include wastewater treatment, ecological friendly biofuel, aquaculture, production of various types of highvalue products such as fatty acids, pigments or antitumor agents useful for cosmetic and drug industries have been developed (gachon et al., 2007; Mata et al., 2010;BrEnnan et al., 2012 Keywords 88Koreivienė J., Kasperovičienė J., savadova K., Karosienė J., vitonytė i.are the leaders among countries that have the largest number of collections (Table 1). Several thousands of strains originated from different climate regions and various types of environments (freshwater, marine, hypersaline or terrestrial) are maintained in the largest culture collections. Nevertheless, the authentic strains isolated from the original localities in the particular region or country is an invaluable reso...

The predation paradox: Synergistic and antagonistic interactions between grazing by crustacean predator and infection by cyanophages promotes bloom formation in filamentous cyanobacteria

“…During culture, D . magna was fed with Crucigeniella apiculata (2013/SPE1/B7) culture grown in MWC medium (Guillard and Lorenzen ), obtained from the Collection of pure cultures of algae and cyanobacteria at Nature Research Centre (Vilnius, Lithuania) (Koreivienė et al ). D .…”

The effects of CdSe/ZnS quantum dots on autofluorescence properties and growth of algae Desmodesmus communis: dependence on cultivation medium

“…The green algae Desmodesmus communis (former Scenedesmus communis (Turpin) Brébisson) isolate 2012/KM/G2 was obtained from the collection of pure cultures of algae and cyanobacteria at the Nature Research Centre, Lithuania. 32 Culture isolate was cultivated as unialgal (but non-axenic) culture in MWC with the addition of selenium at +21 °C under continuous illumination (approximately 100 μmol photons per m 2 s) using a cool white fluorescent light source.…”
