Toxicity propensities of some marine and fresh-water algae as their chemical defense

Beş deniz kahverengi-alg türü, Halopteris scoparia (L.) Sauvagau, Padina vickersiae Hoyt, Dictyota dichotoma (Huds) Lam., Scinaia furcellata L. ve Sargassum natans (L.) J. Meyer, bir deniz yeşil-alg türü, Ulva lactuca L., bir deniz çayırı türü, Posidonia oceanica L., altı tatlı-su yeşil alg türü, Vaucheria sessilis (Vauch.) De Candolle, Zygnema pectinatum (Vauch.) C.A. Agardh, Maugeotia sp. (C.A. Agardh) Wittrock, Cladophora fracta (Dilw.) Kütz, C. glomerata (Dilw.) Kütz ve Spyrogyra gratiana Link. ve su bitkileri Potomogeton perfoliatus L. ile Ranunculus trichophyllus Chaix, tuzlu su karidesi Artemia salina ve deniz tekesi Macrobrachium lanchesteri de Man'a karşı toksisiteleri ile antibakteriyel, antialgal ve pisisidal aktiviteleri yönünden taranmıştır. Bu çalışmada, ayrıntılı sonuçlar verilmektedir.

Kimyasal savunmaları olarak bazı deniz ve tatlı su alglerinin toksisite eğilimleri

Five species of the marine brown-algae, namely Halopteris scoparia (L.) Sauvagau, Padina vickersiae Hoyt, Dictyota dichotoma (Huds) Lam., Scinaia furcellata L., and Sargassum natans (L.) J. Meyer, a species of the marine green-alga, Viva lactuca L., a species of the sea grass, Posidonia oceanica L., six species of fresh-water green-algae, namely Vaucheria sessilis (Vauch.) De Candolle, Zygnema pectinatum (Vauch.) C.A. Agardh, Maugeotia sp. (C.A. Agardh) Wittrock, Cladophora fracta (Dilw.) Kütz, C. glomerata (Dilw.) Kütz, and Spyrogyra gratiana Link., and the aquatic plants, namely Potomogeton perfoliatus L. and Ranunculus trichophyllus Chaix have been assayed for antibacterial, antialgal, piscicidal activities as well as toxicity against brine shrimp Artemia salina and prawn Macrobrachium lanchesteri de Man. Detailed results are given in this study.
