Abstract:
The invention relates to coordination chemistry and biotechnology, in particular to the synthesis of a new coordination compound of iron(III) and 2,6-diacetylpyridine bis(picolinoylhydrazone) (H2L), with biostimulatory properties on exocellular lipase synthesis in mycelial fungal strain Rhizopus arrhizus CNMN FD 03 that may be used in the development of biotechnologies to obtain lipolytic enzymes.
According to the invention, a novel coordination compound perchlorate of 2,6-diacetylpyridine-bis(picolinoylhydrazone)-bis(aqua)iron(III)–hydrate(1/2.5) with the formula
[Fe(H2L)(H2O)2](ClO4)3∙2.5H2O, where H2L represents 2,6-diacetylpyridine bis(picolinoylhydrazone), is claimed. The claimed compound is highly soluble in water, which ensures a practical use as a component of nutrient mediums. The biostimulator ensures the increasing of lipases biosynthesis in the producer by 1.8...10.9% and reduction of duration of cultivation by 24 h.
