Enzymatic degradation of lignin in soil: A review
(MDPI, 2017) Rahul Datta; Aditi Kelkar; Divyashri Baraniya; Ali Molaei; Amitava Moulick; Ram Swaroop Meena; Pavel Formanek
Lignin is a major component of soil organic matter and also a rich source of carbon dioxide in soils. However, because of its complex structure and recalcitrant nature, lignin degradation is a major challenge. Efforts have been made from time to time to understand the lignin polymeric structure better and develop simpler, economical, and bio-friendly methods of degradation. Certain enzymes from specialized bacteria and fungi have been identified by researchers that can metabolize lignin and enable utilization of lignin-derived carbon sources. In this review, we attempt to provide an overview of the complexity of lignin's polymeric structure, its distribution in forest soils, and its chemical nature. Herein, we focus on lignin biodegradation by various microorganism, fungi and bacteria present in plant biomass and soils that are capable of producing ligninolytic enzymes such as lignin peroxidase (LiP), manganese peroxidase (MnP), versatile peroxidase (VP), and dye-decolorizing peroxidase (DyP). The relevant and recent reports have been included in this review. © 2017 by the authors.
Legumes for Carbon and Nitrogen Cycling: An Organic Approach

Food security, land degradation, eliminating the threats of climate change, soil sustainability, and crop productivity are the critical challenges in the coming years. Therefore, the sustainability of the agricultural production system is becoming a central component in enhancing food security and environmental sustainability. Legume crops could play a significant role in this perspective by carrying out numerous services in keeping with principles of sustainability. Incorporating legume crops into crop rotation is essential for implementing and integrating the conservation and improvement of soil health, quality, and fertility with diverse aspects of crop and livestock production into the natural farming systems. The source of nutrition to subsequent crops to maintain a continuous nitrogen (N) supply chain greatly varies with regard to the inclusion of legumes in the cropping system. The crop rotation, including pigeon pea (Cajanus cajan), improved the total N content in the uppermost soil strata by around 100 μg g 1 soils, in comparison. © Springer Nature Singapore Pte Ltd. 2020.
