Detection interior toxins for some cyanophyta in Iraq aquatic environment

الملخص EN

The algal isolates were isolated from the aquatic environment in Iraq which including Oscillatoria pranceps, Anabaena variabilia and Lyngbya diguei.

After the isolation and purification, these isolates were grown on Chu-10 Medium to extract them for knowing their interior compounds.

The gas-mass chromatography technique helps to determine their toxins using GC-MS analysis.

The internal content of Oscillatoria pranceps consists from C13H28, C16H22O4 and C24H38O4 at concentrations 26.34% , 23.24 and 50.42% respectively.

While, Anabaena variabilia contains C16H32O2, C19H38O2, C20H40O2 and C13H26O2 at concentrations reached to 29.65% , 70.35% , 43.13% and 21.65% respectively.

Finally, Lyngbya diguei contains C15H30O, C13H26O2 and C22H42O2 at concentrations of 11.56% , 29.17% and 32.47% respectively.

The compound C19H38O2 (n-Nonadecanoic acid) which found in Anabaena variabilia is considered the more concentration reached to 70.35% which causes skin inflammation.

While, C24H38O4 [Phthalic acid, bis(2-ethylhexyl)ester] which found in Oscillatoria pranceps has concentration of 50.42% which causes endocrine glands.
