Project description:The use of biofertilizers is becoming an economical and environmentally friendly alternative to promote sustainable agriculture. Biochar from microalgae can be applied to enhance the productivity of food crops through soil improvement, slow nutrient absorption and release, increased water uptake, and long-term mitigation of greenhouse gas sequestration. Therefore, the aim of this study was to evaluate the stimulatory effects of biochar produced from Spirulina platensis biomass on the development and seed production of rice plants. Biochar was produced by slow pyrolysis at 300°C, and characterization was performed through microscopy, chemical, and structural composition analyses. Molecular and physiological analyses were performed in rice plants submitted to different biochar concentrations (0.02, 0.1, and 0.5 mg mL-1) to assess growth and productivity parameters. Morphological and physicochemical characterization revealed a heterogeneous morphology and the presence of K and Mg minerals in the biochar composition. Chemical modification of compounds post-pyrolysis and a highly porous structure with micropores were observed. Rice plants submitted to 0.5 mg mL-1 of biochar presented a decrease in root length, followed by an increase in root dry weight. The same concentration influenced seed production, with an increase of 44% in the number of seeds per plant, 17% in the percentage of full seeds per plant, 12% in the weight of 1,000 full seeds, 53% in the seed weight per plant, and 12% in grain area. Differential proteomic analyses in shoots and roots of rice plants submitted to 0.5 mg mL-1 of biochar for 20 days revealed a fine-tuning of resource allocation towards seed production. These results suggest that biochar derived from Spirulina platensis biomass can stimulate rice seed production.

Project description:Long-term consumption of erythritol, a widely used sugar substitute, has been associated with increased risks of thrombosis and cardiometabolic diseases. In this study, we investigated the effects and mechanisms of allulose in mitigating these risks compared to erythritol using the clusterProfiler tool. Since a high-fat diet (HFD) is known to enhance platelet aggregation, we compared the pathways related to these processes between groups of mice treated with allulose and those treated with erythritol. While erythritol exacerbated HFD-induced increased platelet aggregation, allulose treatment significantly reduced it. The groups consisted of a normal diet group (ND, with 10% of calories derived from fat), a high-fat diet group (HFD, with 40% of calories from fat), a high-fat diet with 5% allulose supplementation (ALLU), and a high-fat diet with 5% erythritol supplementation (ERY).

Project description:The four-carbon sugar erythritol is an important component of B. melitensis pathogenesis. To determine the transcriptional response to erythritol, B. melitensis strain 16M was grown in the presence of either glucose or erythritol as a sole carbon source. Two control samples (glucose) and two experimental samples (erythritol) were analyzed on Nimblegen B. melitensis microarray chips.
