Fermentation is a well-recognized strategy to reduce alkaloid content. However, its effectiveness is influenced by the choice of fermentation media. The limited variety of available media complicates the ability to meet the specific formulation requirements of cigar products. Consequently, there is a need to develop additional media to tailor formulations that optimize fermentation outcomes.</p><h3>Results</h3><p>The fermentation media developed in this study were primarily composed of compounds including chlorogenic acid, liquiritin, schaftoside, and ganoderic acid. The fermentation of cigar tobacco leaves with a medium led to a reduction in total nitrogen and alkaloid levels, while simultaneously enhancing both total sugar and reducing sugar contents. Specifically, compared to the control group, the alkaloid content in tobacco leaves treated with the medium decreased by 9.58–19.06%. Furthermore, the addition of the medium resulted in an increase in aroma compounds, while the levels of unsaturated fatty acids decreased by 7.14–24.66%. The medium also elevated the contents of characteristic aroma components, including 3-hydroxy-5,6-epoxy-β-ionol, megastigmatrienone, β-dihydroionone, dihydroactinidiolide, and sclareolide. Additionally, the introduction of the medium altered the bacterial and fungal community structures within the cigar tobacco leaves. It also facilitated the proliferation of functional microorganisms such as <i>Acinetobacter, Enterobacter, Pseudomonas, Wickerhamomyces,</i> and <i>Wallemia.</i> Correlation analysis indicated a positive relationship between the enrichment of these functional microorganisms and the increased levels of aroma compounds, such as 3-hydroxy-5,6-epoxy-β-ionol. From a sensory perspective, the incorporation of the medium reduced irritation and undesirable odors in cigar tobacco leaves, while enhancing the sweetness and richness of the aroma.</p><h3>Conclusions</h3><p>The specialized media developed in this study represent an innovative approach to optimizing cigar tobacco fermentation. This method utilizes unique raw materials and bioactive compounds to coordinate microbial activity, reduce alkaloid level, enhance aroma components, and improve sensory attributes. From an application standpoint, these media could be seamlessly integrated into cigar processing lines to enhance product quality with minimal modifications to existing equipment.

However, the availability of effective products is low, and our understanding of the mechanisms explaining the effects observed is very limited.</p><h3>Results</h3><p>This report describes the combination of a plant growth-promoting bacterium and a novel non-microbial biostimulant previously formulated in-house which increases tomato yield under salt stress. We have also determined many physiological, biochemical, and molecular parameters to characterize the molecular mechanisms underlying the observed yield increase. Our results indicate that the combined effect of both biostimulants promoted the accumulation of proline in roots and flavonoids in leaves, as well as a decrease in the antioxidant response, with the only exception of catalase activity, which was unaltered in leaves, and the ascorbate peroxidase activity, which exhibited a slight increase in roots. In addition, the joint treatment increased the content of the cytokinin isopentenyladenine riboside (IPR) in roots and leaves and promoted a significant accumulation of Krebs cycle intermediates under salt stress.

However, its downstream application has not been well-addressed thus restricting P cycling. This study investigated the P fertilizer efficiency of vivianite in pot experiments using ryegrass (<i>Lolium multiflorum</i> L.) and tomato (<i>Solanum lycopersicum</i> L.) with two soilless growing media (perlite and quartz). The variation of vivianite during fertilization was examined to elucidate the mechanisms of P release from vivianite, using a recently developed sequential P extraction protocol coupled with light microscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS).</p><h3>Results</h3><p>The mineral fertilizer equivalence (MFE) of vivianite was determined by comparing the P uptake by plants under vivianite treatment to that under mineral P fertilizer treatment, i.e., Ca(H<sub>2</sub>PO<sub>4</sub>)<sub>2</sub> in this study. It shows that the vivianite-P uptake of ryegrass was positively correlated with time in a 3-month period and its uptake in quartz was faster than that in perlite, leading to a higher MFE of vivianite in quartz than in perlite (15.8–20.3% vs 6.6–7.4%). This should be attributed to the higher P adsorption capacity and lower hydraulic conductivity of perlite, which restricted the vivianite-P dissolution and mobility. The vivianite variation revealed that vivianite-P was mainly released upon vivianite oxidation to ferric (hydr)oxides in perlite, probably given the high aeration condition in this type of growing medium. In quartz, however, the release of vivianite-P was most likely due to vivianite dissolution driven by the plant uptake of P, during which a higher plant uptake of Fe was observed than that in perlite.</p><h3>Conclusions</h3><p>The findings reveal that vivianite can serve as a slow-release P fertilizer, and its fertilizer efficiency is highly related to the properties of the growing media. Quartz is a preferred growing medium over perlite for the efficient fertilization of this sparingly soluble P source.
