    Application of lactic acid bacteria in agriculture: perspectives and challenges
    (Odesa I. I. Mechnikov National University, 2016) Limanska, Nataliia V.; Basiul, Olena V.; Kutiian, D.; Saparova, O.; Kononiuk, Yu. V.; Nevynna, T. V.; Arzamasova, A.; Reva, K.; Ivanytsia, Volodymyr O.; Sokol, D.; Ліманська, Наталія Вікторівна; Іваниця, Володимир Олексійович
    Application of lactic acid bacteria for plant protection and stimulation of plant growth started in 1980s with works of Visser et al. (1986) and Higa et al. (1989). Nevertheless, till now there is no clear scientific explanation of the mechanism of growth stimulation. We found out that lactobacilli can increase growth of stems, roots and stimulate the germination of tomatoes, garden cress and wheat (Limanska, 2013; unpublished data). But it also was shown that in consortia the positive capabilities of Lactobacillus plantarum increased. What is the mechanism of such beneficial co-existence? It is still unknown. Only one work of Goffin et al. (2010) described the possible synthesis of plant hormones or hormone-like compounds of L. plantarum. The mechanism of such mutual effects could be based on cell-cell interactions. Induction of bacterial activity of lactobacilli as the result of interaction with microorganisms of other species is known for the synthesis of bacteriocins (Rojo-Bezares, 2007). It is possible that the similar mechanism exists for the synthesis of stimulating compounds.

    Complex investigations of plant microbiota representatives
    (Одеський національний університет імені І. І. Мечникова, 2018) Kononiuk, Yu. V.; Marynova, I. V.; Adarma, N. Yu.; Stepaniuk, G.; Bratkevich, V.; Tverdokhlib, V. S.; Basiul, Olena V.; Limanska, Nataliia V.; Ліманська, Наталія Вікторівна
    Phytopathogenic bacteria - crown gall agents - were isolated from grape plants. Antagonistic bacteria - also plant dwellers - were used to struggle these pathogens. Lactobacillus plantarum effectively inhibited crown gall agents and survived in soil at least for 45 days. Lactobacilli could interfere pathogenesis of the disease on a step of pathogen attachment. Together with Bacillus megaterium, lactobacilli showed stimulation effect on plant growth.

    Effect of Lactobacillus plantarum on agent of damping-off of pine seedlings
    (Одеський національний університет імені І. І. Мечникова, 2018) Adarma, N. Yu.; Kononiuk, Yu. V.; Limanska, Nataliia V.; Ліманська, Наталія Вікторівна
    Effect of some Lactobacillus strains and their combinations on agents of fusariosis of pine Fusarium sp. 17 has been studied. Bacteria of L. plantarum species could be studied as perspective microorganisms for improving germination of Scots pine seeds and protection of seedlings under the certain condition of soil treatment.

    Stimulation and plant protection properties of Lactobacillus plantarum
    (Odessa I. I. Mechnikova National University, 2017) Kononiuk, Yu. V.; Adarma, N. Yu.; Melnikovich, D. B.; Limanska, Nataliia V.; Ліманська, Наталія Вікторівна
    Antagonistic and plant stimulation activities of Lactobacillus plantarum strains were studied. 50% of the studied strains-antagonists caused the complete inhibition of Rhizobium radiobacter C58 on a model of carrot explants Daucus carrota L. If crown gall appeared, the manifestation of symptoms was less as compared with the control. Stimulation activity was studied on a model of seedlings of Quercus robur L. Treatment with L. plantarum suspensions didn’t improve the germination but positively effected the growth of seedlings (7,1-11,0% increase in plant height).
