The quest for scientifically advanced and sustainable solutions is driven by growing environmental and economic issues associated with coal mining, processing, and utilization. Consequently, within the coal industry, there is a growing recognition of the potential of microbial applications in fostering innovative technologies. Microbial-based coal solubilization, coal beneficiation, and coal dust suppression are green alternatives to traditional thermochemical and leaching technologies and better meet the need for ecologically sound and economically viable choices. Surfactant-mediated approaches have emerged as powerful tools for modeling, simulation, and optimization of coal-microbial systems and continue to gain prominence in clean coal fuel production, particularly in microbiological co-processing, conversion, and beneficiation. Surfactants (surface-active agents) are amphiphilic compounds that can reduce surface tension and enhance the solubility of hydrophobic molecules. A wide range of surfactant properties can be achieved by either directly influencing microbial growth factors, stimulants, and substrates or indirectly serving as frothers, collectors, and modifiers in the processing and utilization of coal. This review highlights the significant biotechnological potential of surfactants by providing a thorough overview of their involvement in coal biodegradation, bioprocessing, and biobeneficiation, acknowledging their importance as crucial steps in coal consumption.
对科学先进和可持续解决方案的探索是由与煤炭开采、加工和利用相关的日益严重的环境和经济问题驱动的。因此，在煤炭行业中，人们越来越认识到微生物应用在培育创新技术方面的潜力。基于微生物的煤炭溶解、煤炭选矿和煤粉抑制是传统热化学和浸出技术的绿色替代品，更好地满足了对生态友好和经济可行选择的需求。表面活性剂介导的方法已成为煤炭微生物系统建模、模拟和优化的有力工具，并在清洁煤燃料生产中继续占据重要地位，特别是在微生物共处理、转化和选矿中。表面活性剂（表面活性剂）是一种两亲性化合物，可以降低表面张力并提高疏水分子的溶解度。通过直接影响微生物的生长因子、刺激物和底物，或者间接地作为浮选剂、捕集剂和改性剂在煤炭的加工和利用中，表面活性剂可以实现广泛的性质。本综述通过全面概述表面活性剂在煤炭生物降解、生物加工和生物选矿中的参与情况，强调了表面活性剂的重要生物技术潜力，承认它们在煤炭消耗中作为关键步骤的重要性。
