Abstract Converting crop residues into biochar and subsequently incorporating it soils is a promising strategy to improve carbon sequestration in agroecosystems. However, differences the potential mechanisms for soil organic (SOC) accumulation between its feedstock materials remain unclear. This study performed nine-year field experiment involving four treatments Mollisol: mineral fertilizers alone combined with maize straw or biochar, control without amendments. The main objectives of this were assess how incorporation influence SOC content, chemical composition, microbial necromass (MNC) community characteristics. Compared alone, significantly ( P < 0.05) increased while (40.5% increase) had more pronounced effects than (23.7% increase). Similarly, both MNC content boosted biomass, but impact did biochar. Additionally, markedly aromaticity by 26.6% 0.05), reduced 2.85% > 0.05). Fungi, rather bacteria, played crucial role increasing through their inputs under incorporation. Our results demonstrated that enhanced primarily entombing effect necromass, biochemical protection from recalcitrant aromatic carbon. present findings provide valuable insight practices lead maximize sequestration.

Anti‐inflammatory Polyketides from an Endophytic Fungus Chaetomium sp. UJN‐EF006 of Vaccinium bracteatum

Chemistry & Biodiversity, Год журнала: 2024, Номер 21(4)

Опубликована: Фев. 27, 2024

Seven new polyketides including three chromone derivatives (1-3) and four linear ones incorporating a tetrahydrofuran ring (4-7), along with known compounds (8-10), were obtained from the fermentation of an endophytic fungus (Chaetomium sp. UJN-EF006) isolated leaves Vaccinium bracteatum. The structures these fungal metabolites have been elucidated by spectroscopic means MS, NMR electronic circular dichroism. A preliminary anti-inflammatory screening lipopolysaccharide (LPS) induced RAW264.7 cell model revealed moderate NO production inhibitory activity for 1 4. In addition, expression LPS-induced inflammatory factors IL-6, iNOS COX-2 was also blocked

Changes in the soil fungal communities of steppe grasslands at varying degradation levels in North China

Canadian Journal of Microbiology, Год журнала: 2023, Номер 70(3), С. 70 - 85

Опубликована: Дек. 14, 2023

The grasslands in North China are rich fungal resources. However, the knowledge of structure and function communities role microbial vegetation restoration succession limited. Thus, we used an Illumina HiSeq PE250 high-throughput sequencing platform to study changing characteristics soil degraded grasslands, which were categorized as non-degraded (ND), lightly degraded, moderately severely (SD). Moreover, a correlation analysis between physical chemical properties was completed. results showed that number plant species, coverage, aboveground biomass, diversity index decreased significantly with increasing degradation, there significant differences among different grasslands. dominant phyla grassland follows: Ascomycota, 44.88%-65.03%; Basidiomycota, 12.68%-29.91%; unclassified, 5.51%-16.91%. fungi Mortierella, 6.50%-11.41%;

<i>Arcopilus aureus</i>: a valuable endophytic associate of hazelnut

Acta Agrobotanica, Год журнала: 2023, Номер 76, С. 1 - 11

Endophytic fungi are increasingly being considered for their ecological role and effects on plant protection nutrition. Their contribution in improving fitness can be particularly relevant the case of semi-extensive tree crops, such as hazelnut. In this manuscript, occurrence properties species <i>Arcopilus</i> <i>aureus</i> reviewed, following its finding a component endophytic microbiome hazelnut distant geographic climatic contexts Poland Italy, representing an indication widespread association with possible against biotic adversities.
