Lignocellulosic crop residue (LCCR) composting is a cost-effective and sustainable approach for addressing environmental pollution associated with open biomass burning and application of chemical fertilizers in agriculture. The value-added bio-product of the composting process contributes to the improvement of the soil properties and plant growth in an environment-friendly way. However, the conventional process employed for composting LCCRs is slow and becomes an impediment for farmers who plant two or three crops a year. This concern has led to the development of different techniques for rapid composting of LCCRs. The use of cellulolytic nitrogen-fixing microorganisms for composting has emerged as a promising method for enhancing LCCR composting and quality of the compost. Therefore, this review addresses the recent progress on the potential use of cellulolytic nitrogen-fixing bacteria (CNFB) for LCCR composting and discusses various applications of nutrient-rich compost for sustainable agriculture to increase crop yields in a nature-friendly way. This knowledge of bacteria with both cellulose-degrading and nitrogen-fixing activities is significant with respect to rapid composting, soil fertility, plant growth and sustainable management of the lignocellulosic agricultural waste and it provides a means for the development of new technology for sustainability.
木质纤维素作物残余物 (LCCR) 堆肥是一种经济有效的可持续方法，可解决与生物质露天燃烧和农业化肥应用相关的环境污染问题。堆肥过程中的增值生物制品以环保的方式有助于改善土壤特性和植物生长。然而，用于 LCCR 堆肥的传统方法速度较慢，这对每年种植两到三茬作物的农民来说是一个障碍。这种担忧导致了不同的快速堆肥 LCCR 技术的发展。使用纤维素分解固氮微生物进行堆肥已成为提高 LCCR 堆肥质量的有前途的方法。因此，本综述介绍了纤维素分解固氮菌 (CNFB) 在 LCCR 堆肥中的潜在用途的最新进展，并讨论了富含营养的堆肥在可持续农业中的各种应用，以自然友好的方式提高作物产量。了解具有纤维素降解和固氮活性的细菌对于快速堆肥、土壤肥力、植物生长和木质纤维素农业废弃物的可持续管理具有重要意义，为可持续发展的新技术开发提供了一种手段。
