Enhancing Soil Health Through Biocrusts: A Microbial Ecosystem Approach for Degradation Control and Restoration

Microbial Ecology, Journal Year: 2025, Volume and Issue: 88(1)

Published: Feb. 22, 2025

Escalating global concerns about soil degradation, driven by erosion, salinization, compaction, pollution, and organic matter loss, highlights the critical need for sustainable remediation. Biocrusts—complex communities of cyanobacteria, algae, lichens, bryophytes, fungi—play a pivotal role in stabilization, erosion prevention, nutrient cycling. This study presents recent advancements biocrust application management restoration, focusing on artificial biocrusts as nature-based solution biotechnology. It emphasizes their effectiveness enhancing quality, biodiversity, ecosystem functionality. Researchers are leveraging these microbial to develop strategies that improve health rehabilitate degraded landscapes. The review concludes viable strategy boosting resilience against environmental stressors. recommends future research long-term ecological impacts methods enhance

Salt stress is common in natural environments, where elevated salt levels brackish water and saline soil can hinder the growth of organisms, thereby exacerbating environmental challenges. Developing salt-tolerant organisms not only uncovers novel mechanisms tolerance but also lays groundwork for managing utilizing environments. Cyanobacteria, which are widely distributed hydrosphere soil, serve as ideal models studying stress. In this study, model cyanobacterium Synechocystis sp. PCC 6803 was selected, whose (NaCl) improved from 4.0% to 6.5% (m/v) through adaptive laboratory evolution. Genome re-sequencing mutant analysis identified six key genes associated with tolerance. Notably, deletion slr1670, encodes glycerol glucoside hydrolase, strain's addition, slr1753 a membrane protein that may enhance by facilitating ion transport extracellular space. Further revealed overexpression significantly accumulates Na+ on cell surface, enabling effective seawater treatment using engineered strain, resulting 6.35% reduction seawater. Moreover, adapted bacteria be used remediation samples, leading 184.2% 43.8% increase germination rate average height Brassica rapa chinensis, respectively, along 25.3% rise total organic carbon content reductions both 1.82% pH 1.91% soil.
