Cyanobacterial blooms and toxins in water resources:
Occurrence, impacts and management
Short Term Scientific Mission (STSM)
Creation of AACC
(Åbo Akademi Culture Collection)
Objectives
Creation of culture collection named AACC (Åbo Akademi Culture Collection) that represents an
important way of biodiversity preservation of a specific region, but also it offers the possibility of
target selection and use of microorganisms in various fields of science and technology.
Methodology
Sampling on sites where cyanobacterial growth has been observed:
lakes Köyliönjärvi, Pyhäjärvi, Vähäjärvi; Åland Islands:
lakes Nätö Hemviken, Brantsböle Träsk, Baltic Sea.
Isolation of individual cells, filaments and colonies by:
-successive multiplication on solid and liquid media,
-separation using a micropipette.
Purification:
-each culture was spread onto 3 universal growth media
to test bacterial and fungal growth.
Identification and determination
-performed by microscopy work.
Cultivation of biomass
-in media with and without nitrogen
-at room temperature
-illumination with 20 W PowerGlo fluorescent lamps
-light cycle 16 h light - 8 h dark.
Preservation
Recommended methods for preservation of axenic cyanobacterial culture is lyophilization and
cryopreservation as the most reliable and safest way of culture preservation for a long period of
time.
Database creation will make all information related to cyanobacterial cultures available and
affordable to individuals and institutions who want to benefit from the collection.
Results
AACC counts 52 strains isolated from water and terrestrial ecosystems. With the identification of
strains to the genus level, it was found that all isolated strains belong to 17 genera:
Chroococcus, Merismopedia, Cylindrospermum, Woronichinia, Geitlerinema, Gleocapsa,
Microcystis, Oscillatoria, Phormidium, Aphanizomenon, Anabaena, Nostoc, Rivularia, Calothrix,
Tolypothrix and Scytonema.
