Synthesis of sodium titanates and their use in the photocatalytic degradation of NO.

The synthesis and characterization of sodium titanates (ST), and their evaluation in the photocatalytic reduction of nitric oxide (NO) are described herein. The materials were synthesized by a hydrothermal route using 5 M NaOH as the mineralizer agent and a TiO content of 0.06 mg/mL (expressed as the mass ratio of TiO/mL of NaOH), at 170 °C for 48 h, resulting in sodium tri- and hexa-titanates.

Optimized Production of a Redox Metabolite (pyocyanin) by NEJ01R Using a Maize By-Product.

metabolizes pyocyanin, a redox molecule related to diverse biological activities. Culture conditions for the production of pyocyanin in a defined medium were optimized using a statistical design and response surface methodology. The obtained conditions were replicated using as substrate an alkaline residual liquid of cooked maize and its by-products.
