From Bench to Greenhouse: The Comparative Nano-Bio System Effects of Green-Synthesized TiO₂-NPs and Plant-Growth-Promoting Microorganisms in <i>Capsicum annuum</i>.

ABSTRACT: In this study, titanium dioxide nanoparticles (TiO₂-NPs) were produced via green routes using blueberry extracts obtained with isopropanol (I-TiO₂-NPs) and methanol (M-TiO₂ NPs). HPLC-DAD confirmed phenolic/flavonoid profiles in the extracts, and spectroscopy/microscopy established anatase, polyhedral, mesoporous TiO₂-NPs with Eg ≈ 3.0 eV, hydrodynamic sizes ≈ 130-150 nm and negative ζ-potentials (-33 to -50 mV). The in vitro compatibility between TiO₂-NPs and the plant-growth-promoting microorganisms (PGPMs) Bacillus subtilis (Bs), Bacillus thuringiensis (B), and Trichoderma harzianum (T) sustained increased growth up to 150 µg/mL without visible negative effects.
