The aim of the present work is to evaluate the ability of 'fungi' for the biodegradation of recalcitrant xenobiotic compound, 'Atrazine' in batch liquid cultures. Different parameters like pH (2.0-8.0) temperature (16-32 °C), biomass (1-5 g), and concentration (25-100 ppm) were optimized for the efficient degradation of atrazine. The decomposition behavior of atrazine is analyzed with the help of Fourier Transform Infrared (FTIR) spectroscopy. Herein, we have reported that the Bjerkandera adusta possess high removal efficiency of the xenobiotic compound (atrazine) up to 92%. The fungal strain investigated could prove to be a valuable active pesticide degrading micro-organism, with high detoxification values. These results are useful for improved understanding and prediction of the behavior and fate of B. adusta in the bio-purification of wastewater contaminated with xenobiotics. Thus providing a new and green approach for the remediation of toxicants without altering the environmental components.
本研究旨在评估真菌对难降解外来化合物莠去津的生物降解能力，采用批量液体培养。优化了不同参数，如 pH（2.0-8.0）、温度（16-32°C）、生物量（1-5 g）和浓度（25-100 ppm），以实现莠去津的高效降解。采用傅里叶变换红外（FTIR）光谱分析莠去津的分解行为。在此，我们报道了粗糙脉孢菌具有较高的去除效率（高达 92%），可以去除外来化合物（莠去津）。所研究的真菌菌株可以作为一种有价值的活性农药降解微生物，具有较高的解毒值。这些结果有助于更好地理解和预测 B. adusta 在生物净化含有外来污染物的废水中的行为和命运。因此，为在不改变环境成分的情况下修复有毒物质提供了一种新的绿色方法。
