Abstract

Bacterial nanocellulose (BNC), an exo-polysaccharide yielded by aerobic bacteria has gained ample recognition during the last several years. Owing to its eccentric physical and chemical properties in contrast to plant cellulose, it has prompted researchers to explore the resources derived from bacteria, which are imperishable and eco-friendly. BNC can adsorb many classes of pollutants as well as soluble organic pollutants, oil, dyes, heavy metals, and unbidden contaminants from sewage. Ex-situ modification of BNC with certain composites has emanated as an advanced grade of improved bio-based adsorbent with propitious application in environmental remediation and treatment of wastewater. This chapter presents an overview of the available details on BNC as a new class of bio-adsorbent with special prominence on its yield and environmental applications. Additionally, the review also highlights the mechanism of BNC-based adsorbents for wastewater treatment, specifically as dye and heavy metal adsorbents.

细菌纳米纤维素:用于绿色修复技术的新型纳米结构生物吸附剂

细菌纳米纤维素（BNC）是一种由好氧细菌产生的胞外多糖，在过去几年中得到了广泛的认可。与植物纤维素相比，由于其独特的物理和化学性质，它促使研究人员探索来自细菌的资源，这些细菌是不朽的，也是环保的。BNC可以吸附多种污染物，还可以吸附污水中的可溶性有机污染物、油类、染料、重金属和未结合的污染物。用某些复合材料对BNC进行原位改性是一种先进的生物基吸附剂，在环境修复和废水处理中有着良好的应用前景。本章概述了BNC作为一种新型生物吸附剂的可用细节，特别突出了其产量和环境应用。此外，该综述还强调了BNC基吸附剂用于废水处理的机理，特别是作为染料和重金属吸附剂。
