“…Previous studies of Tverdokhlib et al [18], Teslyuk et al [10] and Dahmani et al [5] indicate the significant phytostimulatory effect of B. megaterium strains on plant growth, development of roots and vital functions [5; 10; 18]. Literature data indicated that cultural medium LB by itself did not cause the stimulation effect [16] but in majority of cases inhibited plant growth [6]. The results of our previous studies also have shown the inhibitory effect of LB and LB mixed with MRS medium on germination and plants growth [2; 3].…”

The aim of the study was to evaluate the effect of Bacillus megaterium ONU 500 on the germination and growth of sunflower seedlings. Materials and methods. Sunflower seeds were sown in containers with soil inoculated with a suspension of bacteria B. megaterium ONU 500 in concentration of 106 CFU/ml. After 21 days growth characteristics of seedlings were compared: germination, average height, root length, leaf area, dry weight. Effect of these microorganisms on biofilm formation on roots was investigated with light microscopy. Results. Inoculation of soil with B. megaterium ONU 500 resulted in the positive effect on roots length (increase by 21%), leaf area (increase by 22%) and dry weight of seedlings (increase by 17.8%). No significant effect on germination and plant height was observed. On the roots of plants grown in soil treated with B. megaterium ONU 500 more developed biofilms with well formed matrix were observed, which indicates the stimulation of ability of plant and soil microbiota to form biofilms in presence of bacilli from the studied strain. Conclusion. The investigations demonstrated that bacteria of B. megaterium ONU 500 strain caused a positive effect on development of sunflower seedlings and formation of biofilms on their roots.

Currently, the tropics harbor a wide variety of crops to feed the global population. Rapid population expansion and the consequent major demand for food and agriculture-based products generate initiatives for tropical forest deforestation, which contributes to land degradation and the loss of macro and micronative biodiversity of ecosystems. Likewise, the entire dependence on fertilizers and pesticides also contributes to negative impacts on environmental and human health. To guarantee current and future food safety, as well as natural resource preservation, systems for sustainable crops in the tropics have attracted substantial attention worldwide. Therefore, the use of beneficial plant-associated microorganisms is a promising sustainable way to solve issues concerning modern agriculture and the environment. Efficient strains of bacteria and fungi are a rich source of natural products that might improve crop yield in numerous biological ways, such as nitrogen fixation, hormone production, mobilization of insoluble nutrients, and mechanisms related to plant biotic and abiotic stress alleviation. Additionally, these microorganisms also exhibit great potential for the biocontrol of phytopathogens and pest insects. This review addresses research regarding endophytic and rhizospheric microorganisms associated with tropical plants as a sustainable alternative to control diseases and enhance food production to minimize ecological damage in tropical ecosystems.
