Mangroves are dynamic and unique ecosystems which provide important ecological services to coastal areas. The phylloplane is one of the greatest microbial hosts and most of their microorganisms are uncultivated, thus having the potential to house novel bacteria species. Bacterial community structure of L. racemosa phylloplane, a well-adapted mangrove species with salt exudation at foliar levels, was accessed through 16S rRNA amplicon sequencing. Sampling was performed at Cananéia mangrove in São Paulo state, Brazil in three different sites across a transect from the upland to the seashore. There was significant effect of the sites in the bacterial microbial community along the transect. Higher diversity was observed in intermediary locations between the upland to the seashore, indicating that the intermediary salinity had a strong effect in bacteria diversity favoring the occurrence of k-strategist groups and increasing the rates of uncultivated bacteria. Thus, salinity had a positive effect in bacteria diversity but further studies on the ecology of these salinity-tolerant, uncultivated organisms can be explored to elucidate the structuring mechanisms of these communities in this habitat. |

Intensive fertilization has been required to provide nutrients for plant growth under the current agricultural practices being applied to meet the global food demands. Micronutrients such as zinc, manganese, and copper are required in small quantities when compared to macronutrients (such as nitrogen, phosphorus and potassium), but they are essential for the plant growth cycle and consequently for increasing productivity. Mineral oxides such as ZnO, MnO, and CuO are used in agriculture as micronutrient sources, but their low solubility limits practical applications in plant nutrition. Similarly, elemental sulfur (S0) can provide a high-concentration source of sulfate, but its availability is limited by the ability of the soil to promote S0 oxidation. We propose here the integration of these nutrients in a composite based on a biodegradable starch matrix containing mineral oxides and S0 in a dispersion that allowed encapsulation of the acidifying agent Aspergillus niger, a native soil fungus. This strategy efectively improved the fnal nutrient solubility, with the composite starch/S0/oxidemixture multi-nutrient fertilizer showing remarkable results for solubilization of the oxides, hence confrming a synergic efect of S0 oxidation and microbial solubilization. This composite exhibited an extended shelf life and soil?plant experiments with Italian ryegrass (Lolium multiforum Lam.) confrmed high efciencies for dry matter production, nutrient uptake, and recovery. These fndings can contribute to the development of environmentally friendly fertilizers towards a more sustainable agriculture and could open up new applications for formulations containing poorly soluble oxide sources.
