Abstract：
Myxotoxins can contaminate algal-based products and arrive to the food chain to consumers producing chronic toxicity effects. Here, we studied phytotoxicity of mycotoxins, beauvericin (BEA) and ennaitin B (ENN B) in four phytoplankton strains: Acutodesmus sp., Chlamydomonas reinhardtii, Haematococcus pluvialis, and Monoraphidium griffithii, which are all green algae. It was tested the capacity of clearing the media of BEA and ENN B at different concentrations by comparing nominal and measured quantifications. Results revealed that Acutodesmus sp. and C. reinhardtii tended to flow up and down growth rate without reaching values below 50% or 60%, respectively. On the other hand, for H. pluvialis and M. griffith, IC50 values were reached. Regarding the clearance of media, in individual treatment a decrease of the quantified mycotoxin between nominal and measured values was observed; while in binary treatment, differences among both values were higher and more noted for BEA than for ENN B.
摘要：
粘液毒素会污染基于藻类的产品，并到达食物链对消费者产生慢性毒性作用。这里,我们研究了霉菌毒素的植物毒性,四种浮游植物菌株中的Beauvericin（BEA）和ennaitinB（ENNB）：Acutodesmussp。,莱茵衣藻,雨生红球菌,和格列菲诺兰,都是绿藻。通过比较标称和测量的定量来测试在不同浓度下清除BEA和ENNB的培养基的能力。结果表明，针具。和C.reinhardtii倾向于上下流动的增长率没有达到低于50%或60%的值，分别。另一方面,对于H.pluvialis和M.griffith,达到IC50值。关于清除媒体，在单独治疗中，观察到标称值和测量值之间的定量霉菌毒素减少；而在二元治疗中，与ENNB相比，BEA的两个值之间的差异更高，更明显。
