This work aimed to study the profiling and efficiency of microbial communities and their abundance in the pulp and paper industry wastewater, which contained toxic metals, high biological oxygen demands, chemical oxygen demand, and ions contents. Sequence alignment of the 16S rRNA V3-V4 variable region zone with the Illumina MiSeq framework revealed 25356 operating taxonomical units (OTUs) derived from the wastewater sample. The major phyla identified in wastewater were Proteobacteria, Bacteroidetes, Firmicutes, Chloroflexi, Actinobacteria, Spirochetes, Patesibacteria, Acidobacteria, and others including unknown microbes. The study showed the function of microbial communities essential for the oxidation and detoxifying of complex contaminants and design of effective remediation techniques for the re-use of polluted wastewater. Findings demonstrated that the ability of different classes of microbes to adapt and survive in metal-polluted wastewater irrespective of their relative distribution, as well as further attention can be provided to its use in the bioremediation process.
本研究旨在研究含有毒金属、高生物需氧量、化学需氧量和离子含量的制浆造纸工业废水中微生物群落的特征和效率及其丰度。Illumina MiSeq 框架下的 16S rRNA V3-V4 可变区序列比对显示，废水样品中可得到 25356 个操作分类单元（OTUs）。废水中鉴定的主要门包括变形菌门、拟杆菌门、厚壁菌门、绿弯菌门、放线菌门、螺旋体门、浮霉菌门、酸杆菌门和其他未知微生物。该研究表明了微生物群落对于氧化和解毒复杂污染物的功能，以及设计有效的修复技术以重新利用污染废水的重要性。研究结果表明，不同类别的微生物具有适应和在金属污染废水中生存的能力，而不考虑其相对分布，因此可以进一步关注其在生物修复过程中的应用。
