椰壳髓是一种含有农业的和工业的多酚残留造成土地和水的污染。研究项目正在利用棕髓作为生物能源生产,衬底和氧化delignificationwas pretreatmentmethod报道作为有效。过程生成高度彩色氧化脱木素‘棕黑色髓LiquorA’(CBL)废水和开放的环境带来污染风险的释放。CBL毒性的评价意义的安全处理计划。在目前的研究中,我们调查了药害CBL标准测试物种栽培稻。96小时进行了生物测定。根长度、拍摄长度,种子发芽,发芽指数(GI),种子活力指数(SVI)和拍摄toRoot比率(S, R)的参数进行了研究。数据采集是借助图像分析软件‘FijiA’。统计分析进行了使用‘RA’软件。EC50的半数有效浓度)的浓度减少50%增长,控制相比,发生了每个参数的计算。 The EC50s were converted into Toxic Units (TU) for comparison. All parameters studied were significantly affected by the CBL. The study revealed that CBL was acutely toxic to Oryza sativa. Root length and Germination Index (GI) were the most sensitive endpoints (TUs = 8.9 and 8.8 respectively) whereas seed germinationwas the least sensitive endpoint (TU = 1.73). Based on sensitivity, the parameters were arranged as : Root length=GI>Seedling length=SVI>Shoot length>Germination. The results points towards the necessity of further characterization of toxicants present in the CBL and treatment procedures to eliminate the toxicity.
