“…Even as an isolated particle, lignin can reduce enzyme activity by inducing non-productive binding sites for cellulase and other microbial proteins in the soil, reducing their activity [50]. The degradation of lignin can also lead to the formation of other inhibitory antimicrobial products, such as humic materials and phenolics that can reduce enzyme activity [14][15][16][17]19].…”

“…Lignin also forms ether bonds with the carbohydrate components, thus reducing accessibility of enzymes to carbohydrates [17,18]. When lignin degrades it forms other antimicrobial compounds such as humic acids, which also reduce degradation [19]. Each of these pathways can independently cause lignin to reduce the degradation rate of carbohydrates [14].…”

Pure cellulose nanofibers (CNFs) rapidly degrade in soil, limiting their prospective applications in agriculture. We incorporated lignin into CNFs as an antimicrobial and crosslinking agent to control the biodegradation rate. CNFs with different lignin concentrations were prepared by mechanochemical treatment in the presence of choline chloride-urea deep eutectic solvent. These were characterized using conductometric titration, scanning electron microscopy, and FT-IR. The fibers were applied to soil to determine the effect of lignin on soil respiration and nanocellulose degradation, and were used as a substrate for radish and cress seed germination. Modifying the lignin content of the fibers successfully modulated the biodegradation rate in soil. Fibers containing 35% lignin degraded 5.7% in 14 days, while fibers with 20% lignin degraded 20.8% in 14 days. Nanofiber suspensions showed low chemical inhibition for the germination of radish and cress seeds but higher lignin contents reduced the imbibition rate as a seed coating. This study presents the first use of lignin to control the biodegradation rate of cellulose nanofibers in a one-pot, scalable and sustainable system, allowing the advancement of lignocellulose nanofibers for applications such as seed coatings, mulches, and controlled release fertilizers.

“…forestry and agricultural practices, timber industries, agroindustries -meat processing, for example-, yards, sewage). Composting lignocellulose waste can represent an interesting recycling strategy in order to provide useful amendments (fertilizers or organic substrates) for land applications in agriculture and silviculture with beneficial effects on the environment (Hubbe et al 2010;Hubbe 2014). At the same time, recycling such complex waste by composting can be a real challenge for researchers, given its low decomposition rate (i.e.…”

Vegetal fibers from different sources, including wood fibers and plant-derived fibers, together with polymer plastics per se (natural, synthetic, and their blends), as well as their combinations as composite materials may generate significant amounts of wastes. These will undergo degradation process under exposure to different environmental factors including microorganisms, climatic changes – e.g. droughts, oxygen, temperature, soil dynamics, UV radiation, etc. This survey offers a concise review of degradation under environmental conditions, mainly after in-soil exposure, of waste made of polymer materials and natural fibers. It also describes the most common methods for evaluation of bioconversion and degradation, as well as the structural properties after degradation (e.g. macroscopic investigation; weight loss; spectrometry – UV, FTIR, NMR; X-ray diffraction for crystalline changes; SEM microscopy; and thermal stability).
