Abstract

Environmental contamination is growing on daily basis, even though numerous corrective measures have been in practice but still it remains to be a major concern for protecting natural environment, ecosystem and well-being of living systems. Bio products and surface active substances derived from microorganisms and plants are having multiple roles in the environmental protection and cleaning. The amphiphilicity of biosurfactants (BS) causes hydrophilic and hydrophobic regions to come into contact with one another, changing the interfacial and surface tension between them. This phenomenon makes the recalcitrant pollutants more bioavailable and helps the microorganisms to degrade them easily. Additionally, the non-toxic, biodegradable and pH and temperature tolerance of biosurfactants make them better candidates for bioremediation. BS including rhamnolipids, surfactins, saponins and sophorolipids are extensively used for several environmental applications. BS are also used in various nanotechnological applications. BS mediated nano materials and agents are finding enhanced environmental applications than nanoparticles/ materials. This review highlights the numerous environmental issues addressed by using various biosurfactants as well as the methods and mechanisms adopted for the effective degradation and removal of hazardous pollutants.
环境污染的灵丹妙药——生物表面活性剂在生物修复中的作用综述
环境污染日益严重,尽管已经采取了许多纠正措施,但仍然是保护自然环境、生态系统和生命系统福祉的一个主要问题。来源于微生物和植物的生物制品和表面活性物质在环境保护和清洁中具有多种作用。生物表面活性剂(BS)的两亲性使亲疏水区相互接触,改变了它们之间的界面和表面张力。这种现象使顽固的污染物更具生物可利用性,并有助于微生物容易地降解它们。此外,生物表面活性剂的无毒、可生物降解、耐pH和耐温等特性使其成为生物修复的理想选择。包括鼠李糖脂、表面素、皂苷和苦参脂在内的BS广泛用于多种环境应用。BS也用于各种纳米技术应用。与纳米颗粒/材料相比,BS介导的纳米材料和试剂正在发现更好的环境应用。本文综述了各种生物表面活性剂所解决的众多环境问题,以及用于有效降解和去除有害污染物的方法和机制。
