METHOD OF PRODUCTION OF BIOSILICATED NANOTUBES Russian patent published in 2015 - IPC C12N1/12 B82B3/00 

FIELD: nanotechnology.

SUBSTANCE: method of production of biosilicated nanotubes is proposed. The method comprises culturing cyanobacteria in sodium silicate solution, neutralised with hydrochloric acid and mixed with a nutrient medium Z-8, incubation with the replacement and removal of the nutrient medium. The subsequent treatment with the solution of hydrogen peroxide, heating and washing with distilled water is carried out. The culturing cyanobacteria is carried out in nutrient medium Z-8, additionally comprising 0.05 g/l ammonium chloride, with a ratio of sodium silicate solution neutralised with 2M HCl, and the medium Z-8 5:1. The culturing is carried out in the bioreactor at a temperature 25°C under constant illumination and stirring for 10 days with replacement of the nutrient medium once per 2 days.

EFFECT: invention enables to obtain biosilicated nanotubes in a shorter time and with less thickness.
