Biochar-bacteria-plant combined potential for remediation of oil-contaminated soil

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: May 21, 2024

Oil pollution is a common type of soil organic that harmful to the ecosystem. Bioremediation, particularly microbe-assisted phytoremediation oil-contaminated soil, has become research hotspot in recent years. In order explore more appropriate bioremediation strategies for oil contamination and mechanism remediation, we compared remediation effects three plants when applied combination with microbial agent biochar. The combined approach Tagetes erecta , agent, biochar exhibited best plant growth highest total petroleum hydrocarbons degradation efficiency (76.60%). addition, all methods provided varying degrees restoration carbon nitrogen contents soils. High-throughput sequencing found community diversity richness were enhanced most restored Some microorganisms associated promotion such as Cavicella C1_B045 Sphingomonas MND1 Bacillus Ramlibacter identified this study, among which was major component agent. positively correlated indicators tested substantially enriched rhizosphere T. . Functional gene prediction bacterial based on KEGG database revealed pathways carbohydrate metabolism amino acid up-regulated during This study provides potential method efficient soils thoroughly examines biochar–bacteria–plant mechanisms well from perspective communities.

Diseased-induced multifaceted variations in community assembly and functions of plant-associated microbiomes

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 14

Published: March 16, 2023

Plant-associated microorganisms are believed to be part of the so-called extended plant phenotypes, affecting growth and health. Understanding how plant-associated respond pathogen invasion is crucial controlling diseases through microbiome manipulation. In this study, healthy diseased (bacterial wilt disease, BWD) tomato (Solanum lycopersicum L.) plants were harvested, variations in rhizosphere root endosphere microbial communities subsequently investigated using amplicon shotgun metagenome sequencing. BWD led a significant increase bacterial diversity but reduced endosphere. The ecological null model indicated that enhanced deterministic processes both Network analysis showed co-occurrence complexity was increased BWD-infected plants. Moreover, higher universal dynamics observed rhizosphere. Metagenomic revealed enrichment more functional gene pathways infected More importantly, when with BWD, some plant-harmful such as quorum sensing significantly enriched, while plant-beneficial streptomycin biosynthesis depleted. These findings broaden understanding plant-microbiome interactions provide new clues underlying mechanism behind interaction between BWD.

Effects of reductive soil disinfestation combined with different types of organic materials on the microbial community and functions

Microbiology Spectrum, Journal Year: 2024, Volume and Issue: 12(2)

Published: Jan. 17, 2024

Reductive soil disinfestation (RSD) is an effective method to inhibit soilborne pathogens. However, it remains unclear how RSD combined with different types of organic materials affects the ecosystems perennial plants. Pot experiments were conducted investigate effects incorporated perilla (PF), alfalfa (MS), ethanol, and acetic acid on properties, enzyme activities, microbial communities functions, seedling growth. Results showed that RSD-related treatments improved properties changed community composition structure, enhanced interactions facilitated Compared CK, increased pH, available nitrogen, potassium contents, sucrase catalase decreased electric conductivity values. Meanwhile, treatment also significantly reduced relative abundance Fusarium while increasing Arthrobacter, Terrabacter, Gemmatimonas. The reduction was more evident in PF MS treatment, suggesting potential for solid agricultural wastes suppress Furthermore, network complex interconnected, functions related carbon, sulfur, hydrogen cycling increased, bacterial fungal plant pathogens decreased. Importantly, promoted seed germination In summary, better than liquid easily degradable compounds by regulating function improve quality promote growth.IMPORTANCEReductive practice. We found compounds, may proliferation pathogenic bacteria, contribute growth replanted crops. Thus, compounds.

Plant Growth-Promoting Rhizobacteria Are Key to Promoting the Growth and Furanocoumarin Synthesis of Angelica dahurica var. formosana under Low-Nitrogen Conditions

Journal of Agricultural and Food Chemistry, Journal Year: 2024, Volume and Issue: 72(13), P. 6964 - 6978

Published: March 25, 2024

Microbiomes are the most important members involved in regulation of soil nitrogen metabolism. Beneficial interactions between plants and microbiomes contribute to improving utilization efficiency. In this study, we investigated Apiaceae medicinal plant Angelica dahurica var. formosana. We found that under a low-nitrogen treatment, abundance carbon metabolites rhizosphere secretions A. formosana significantly increased, thereby promoting ratio C N nonrhizosphere soils, increasing sequestration, shaping microbial community composition, thus higher yield furanocoumarin synthesis. Confirmation through construction synthetic feedback experiments indicated beneficial growth-promoting rhizobacteria play crucial role efficiency selectively regulating synthesis target furanocoumarins low conditions. These findings may additional theoretical evidence for understanding mechanisms interaction microorganisms.
