The use of endophytic fungi for management of phenol residue in paper and pulp industries has been shown as cost-effective and eco-friendly approach. In this study, isolation of endophytic fungi from roots, stems, and leaves of was conducted. Additionally, the isolated fungi were examined for their ability to degrade phenol and its derivatives in paper and pulp industrial samples, using different growth conditions.
Out of 35 isolated endophyitc fungi, 31 were examined for their phenol biodegradation capacity using Czapek Dox broth medium containing Catechol and Resorcinol as a sole carbon source at final concentrations of 0.4, 0.6 and 0.8%.
A total of 35 fungal species belonging to 18 fungal genera were isolated and identified from different parts of plants. All strains have the capability for degrading phenol and their derivatives with variable extents. The optimum condition of degrading phenol in paper and pulp effluent samples by 11r7 were at pH 3-5, temperature at 28-35°C, good agitation speed at no agitation and 100 rpm.
All endophytic fungal species can utilize phenol and its derivatives as a carbon source and be the potential to degrade phenol in industrial contaminants.
利用内生真菌处理造纸和纸浆工业中的酚类残留已被证明是一种经济高效且环保的方法。在本研究中,从[植物名称缺失]的根、茎和叶中分离内生真菌。此外,在不同生长条件下,对分离出的真菌降解造纸和纸浆工业样品中酚及其衍生物的能力进行了检测。
在35株分离出的内生真菌中,选取31株,以含有邻苯二酚和间苯二酚作为唯一碳源的察氏培养基,最终浓度分别为0.4%、0.6%和0.8%,检测其对酚的生物降解能力。
从[植物名称缺失]植物的不同部位共分离并鉴定出属于18个真菌属的35种真菌。所有菌株均有不同程度降解酚及其衍生物的能力。11r7降解造纸和纸浆废水样品中酚的最佳条件为pH值3 - 5,温度28 - 35°C,搅拌速度为不搅拌和100转/分钟。
所有内生真菌物种都能利用酚及其衍生物作为碳源,并且具有降解工业污染物中酚的潜力。
