Abstract Background Water stress is a major danger to crop yield, hence new approaches strengthen plant resilience must be developed. To lessen the negative effects of water on wheat plants, present study was arranged investigate role synergistic biochar, trans-zeatin riboside (t-ZR), and Azospirillum brasilense soil improvement enzymatic activity in water-stressed wheat. Results In three-replication experiment comprising four treatments (T 0 : Control, T 1 Drought (DS), 2 DS + t-ZR with 3 A. biochar), we observed notable improvements quality activities plants application biochar. drought stress, Treatment having biochar performs best as compared other significant increased such peroxidase (7.36%), catalase (8.53%), superoxide dismutase (6.01%), polyphenol oxidase (14.14%), amylase (16.36%) plants. Different showed different trends results. Soil organic C, dissolved N also enhanced 29.46%, 8.59%, 22.70% respectively under condition. Conclusions The action creates an effective microbiological environment that supports essential physiological processes during stress. This enhancement attributed improved fertility matter content, highlighting potential these novel strategies mitigating enhancing resilience.

In situ immobilization is a potential approach that can be used to remediate low-to-medium levels of heavy-metal in contaminated-soil. There little known about how modifications soil characteristics may affect Pb's release from soil. The four different amendments, triple-superphosphate and attapulgite were combined Ad-1; zeolite Ad-2; hydroxyapatite humus Ad-3; nano-carbon. These amendments are mostly made phyllosilicate minerals, humus, base nano-carbon, respectively. Results revealed the test amendments' maximal Pb-adsorption capacity varied 7.47 17.67 mg g−1. Surface precipitation ion-exchange found main mechanisms for by Ad-1 Ad-2, while Ad-3 Ad-4 promising among all, according analysis both before after Pb loading. When pH dropped (7-1) or ion-strength rose (0–0.2 M), there was discernible rise Pb-desorption percentages amendments. It determined more effective immobilizing lead contaminated-soils because their high adsorption capacities (12.82 g−1) low-desorption (4.46–6.23%) at ion-strengths 0.01–0.1 mol L−1 ranging 5 7.

Perfluorooctane sulfonate (PFOS) is a prominent perfluorinated compound commonly found in the environment, known to pose various risks human health. However, removal of PFOS presents significant challenges, primarily due limited discovery bacteria capable effectively degrading PFOS. Moreover, single degradation often encounter obstacles individual cultivation and breakdown complex pollutants. In contrast, microbial consortia have shown promise pollutant degradation. This study employed continuous enrichment method, combined with multiple co-metabolic substrates, investigate consortium potential for By employing this methodology, we identified that demonstrated capacity reduce when exposed an optimal concentration methanol. The predominantly comprised Hyphomicrobium species (46.7%) along unclassified microorganisms (53.0%). Over duration 20 days, exhibited notable decrease 56.7% comparison initial level, while considering exclusion adsorption effects. Furthermore, by comparing predicted metabolic pathways genome chloromethane-degrading bacterium, sp. MC1, using KEGG database, observed distinct variations pathways, suggesting role microorganisms.
