The influence of the organo-mineral complex on the growth dynamics of the Scenedesmus quadricauda culture

Abstract

The paper presents data on the biotechnology of growing accumulative cultures of algae Scenedesmus quadricauda when adding organo-mineral complex drag to the culture growth medium. It is shown that the trace elements that make up the drug (trade name “Helavit”), at the studied concentrations, act in various ways stimulating and inhibiting the growth of algological culture. Having a different effect in the concentration range from 0.1 to 1 mg / L. The maximum positive effect is achieved with a drug concentration of 0.3 mg / l (8986 ± 120 103*cells/ ml), which can be recommended for mass cultivation of algae. A possible cause of inhibition of culture growth, at a concentration of 0.1 mg / l (6960 ± 115 103*cells/ ml), are the inhibitory effects of copper and iodine ions.

“…An important task of agriculture is to increase the production of high-quality livestock products. The solution to this problem is considered to be a complete feeding of animals, which is achieved mainly with the help of various mineral additives (Bublik et al, 2003;Golovacheva, Bychkova et al, 2020;Golovacheva, Kozlov et al, 2020;Gubajdullin et al, 2008;Simakov et al, 2020;Nikiforov-Nikishin et al, 2021). It was found that minerals have a positive effect on the metabolic processes and productivity of animals, while increasing the body's resistance to pathogens of infectious diseases (Golovacheva, 2004;Golovacheva, Nikiforov-Nikishin et al, 2019).…”
