“…The fact that blue-green algae could produce 2-methylisoborneol was reported by Tsuchiya et al (102). They found that O. geminata produced MAGA 2-methylisoborneöl, while O. amoena, O. splendida, and Aphanizomenon sp.…”

“…Hydrocarbons had also already been identified in cyanobacteria; their compounds, such as heptadecane, have been observed as major components in different species (Tsuchiya et al 1981, Ozdemir et al 2004, Khairy & El-Kassas 2010. This class of compounds was the second most common in the cyanobacteria extracts, with the sample containing only A. halophytica with the highest number of hydrocarbons (4 compounds).…”

Different solvent extracts from Aphanothece halophytica (A. halophytica) were evaluated for their cytotoxic effects against four human cancer cell lines. The samples demonstrated different percentages of cyanobacteria species populations. The samples containing 100% A. halophytica and 90% A. halophytica showed a significant cytotoxic effect in human breast cancer cells MDA231. The cytostatic effect was demonstrated in MDA231 and human glioblastoma T98G cells regardless of the treatment, resulting in a significant cell cycle arrest in the S phase. The chemical profiles of the extracts were proven to be diverse in qualitative and quantitative compositions. This variability was dependent on the A. halophytica´s abundance in each extract. The 100% A. halophytica extract induced cytotoxic and cytostatic effects in breast cancer cells, and those could be associated with the predominance of fatty acids, hydrocarbons and phthalates, indicating that A. halophytica is an interesting source of novel compound with anticancer effect.

“…T h e production of volatiles by cyanobacteria has also been shown (Jiittner et al 1983;Juttner 1987). They may be partly responsible for the earthy, musty and unpleasant odour and taste of some public water supplies (Tsuchiya et al 1981(Tsuchiya et al , 1982Kikuchi et al 1983;Tsuchiya and Matsumoto 1988). Other possible causes are volatiles such as geosmin or 2-phenyl ethanol produced by fungi (Kikuchi et al 1983), streptomycetes (Burnam 1973; Tsuchiya et al 1978;Tsuchiya et al 1980), or by free living amoebae such as Vannelku spp.…”
