FIRST IDENTIFICATION OF THE CYLINDROSPERMOPSIN (CYN)-PRODUCING CYANOBACTERIUM Cylindrospermopsis raciborskii (WOLOSZYNSKA) SEENAYYA & SUBBA RAJU IN SERBIA

摘要

In this study, is reported the first occurrence of cylindrospermopsin (CYN) in Serbia. CYN is a newly emerging carcinogenic hepatotoxic alkaloid, originally identified in tropical cyanobacteria Cylindrospermopsis raciborskii (Woloszynska) Seenayya et Subba Raju. The research was conducted on a monthly basis from June 2012 to February 2013 in Aleksandrovac Lake, Serbia (42 degrees 29'22" N, 21 degrees 53'54" E). C. raciborskii showed the value of abundance between 0.1 x 10(2) and 2.38 x 10(6) trichomes ml(-1). According to HPLC-PDA analysis CYN concentration ranged between 1.91 and 24.28 mu g l(-1). Maximum concentration of CYN was in November 2012, and the fish kill occurred in the following month.
