Obtaining of a plant growth stimulant and bioinsecticides based on Bacillus Thuringiensis melaninogenic strains

Abstract

Based on insecticidal strains of Bacillus thuringiensis, highly active melanin-synthesizing producer strains were obtained. A waste-free technology has been developed that provides the simultaneous production of biologically active substances - melanin and insecticidal toxins in one production process, which increases the profitability of their production. Due to the photoprotective property of the synthesized pigment, the insecticidal activity of melaninogenic strains was increased. The biostimulating effect of bacterial water-soluble melanin has been shown on a number of different (including important agricultural) plants.
