THE FIRST REPORT OF GEOSMIN AND 2-METHYLISOBORNEOL PRODUCER CYANOBACTERIA FROM TURKISH FRESHWATERS

Water users consider the safety of water according to its aesthetic properties, primarily taste and odour. Geosmin (GEO) 2-methylisoborneol (MIB) are most common odour compounds in freshwaters which cause an earthy musty water. Since human nose can detect these concentrations as low 10 ng/L, it is essential monitor drinking waters before consumer complaints produce a timely solution. Therefore, necessary identify GEO MIB producers manage problem at source. Cyanobacteria one main freshwater ecosystems. In this study, we analyzed 13 samples (9 cyanobacteria cultures from Bafa Lake, Elmalı Dam İznik Küçükçekmece Manyas Lake Taşkısığı 4 environmental Erfelek Günpınar Waterfalls Ömerli Lake) for production by HS-SPME (Head space-solid phase microextraction) coupled with GC-MS (gas chromatography-mass spectrometry). The presence Cyanobacteria-specific synthase genes were also PCR (Polymerase Chain Reaction). Taste was confirmed 2 while yielded positive results PCR. All (3 waterfalls Waterfalls, 1 sample -a reservoir) dominated Nostoc Vaucher ex Bornet & Flahault, Phormidium Kützing Gomont Pseudanabaena Lauterborn. This first report producing Turkish combining microscopy, analytical molecular techniques.
