The results showed that La-AgNPs had optimal size (69.35 nm) and spherical and cubical shapes. Moreover, the consumption of La-AgNPs orally caused a significant decrease in gastric ulcer index and gastric juice volume, as well as an increase in pH. In addition, tissue nitric oxide (NO), superoxide dismutase, catalase, and glutathione levels increased and serum NO, reactive oxygen species, and malondialdehyde levels decreased in rats pre-treated with La-AgNPs and famotidine drug compared to the ethanol group. The histopathological results confirmed the above cases.

The biophysical characteristics of Se-NPs were evaluated using techniques like ultraviolet–visible spectroscopy, fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction, dynamic light scattering, scanning electron microscopy (SEM), atomic force microscopy (AFM) and electron probe microanalysis (EPMA). SEM and AFM analyses revealed spherical Se-NPs with an average diameter of 47.6 nm.

Nanopriming with Se-NPs demonstrated a significant, dose-dependent increase in germination activity. This was evident in mean germination time (65 %), radicle and plumule length, fresh weight, and biochemical assays for total soluble sugar and protein content. Additionally, seed vigour and relative water uptake measurements strongly indicated that Se-NPs effectively boost germination and seedling growth. The reduction of free radicals was observed by 3,3′-diaminobenzidine and nitro blue tetrazolium staining, indicating strong antioxidant activity by application of Se-NPs. The increased activities of enzymes superoxide dismutase (SOD ≥28 %), catalase (CAT ≥46 %), peroxidase (POD ≥49 %), along with marked reduction in lipid peroxidation (MDA ≥23 %) evidently demonstrated that Se-NPs enhanced antioxidant defense.

The solvent-tolerant <em>Serratia marcescens</em> demonstrates a high potential for geraniol production, so it was selected as a host for the production of geraniol. We constructed a geraniol biosynthetic pathway in <em>S. marcescens</em> HBQA7 by integrating seven enzymes with high expression activity, successfully achieving the production of geraniol. To enhance the biosynthesis of isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP), we engineered the downstream pathway of the mevalonate (MVA) pathway by rearranging the order of phosphomevalonate kinase (PMK), phosphomevalonate decarboxylase (PMD), and isopentenyl diphosphate isomerase (IDI). Furthermore, an optimal geraniol synthase (ObGES) from <em>Ocimum basilicum</em> was determined for geraniol biosynthesis by evaluating five different geraniol synthases (GES). To further increase the production of geranyl pyrophosphate (GPP), we compared different geranyl diphosphate synthase (GPPS) and found that the enzyme derived from <em>Abies grandis</em> (AgGPPS) was the most effective. Based on these findings, we optimized the linker sequences for fusion expression, thereby improving geraniol production efficiency. Ultimately, the geraniol titer reached 947.6 mg/L in shake flask fermentation. Upon scaling up the process, the geraniol production further increased to 2976.2 mg/L in 5 L bioreactor.
