“…Pseudomonas and Sphingomonas could degrade aromatic amino acids [ 23 ]. Sphingobacterium along with Acromobacter Xylosoxidans, Cupriavidus were closely correlated with the formation of valine, glutamic acid and leucin [ 24 , 25 ]. The fungal diversity of FT has been rarely reported.…”

Background The aging process in the tobacco production, as in other food industries, is an important process for improving the quality of raw materials. In the spontaneous aging, the complex components in flue-cured tobacco (FT) improve flavor or reduce harmful compounds through chemical reactions, microbial metabolism, and enzymatic catalysis. Some believed that tobacco-microbe played a significant part in this process. However, little information is available on how microbes mediate chemical composition to improve the quality of FT, which will lay the foundation for the time-consuming spontaneous aging to seek ways to shorten the aging cycle. Results Comparing aged and unaged FT, volatile and non-volatile differential compounds (DCs) were multi-dimensionally analyzed with the non-targeted metabolomes based on UPLC-QTOP-MS (the ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry), GC–MS (gas chromatography-mass spectrometer) assisted derivatization and HP-SPME-GC/MS (headspace solid-phase micro-extraction assisted GC–MS). Products associated with the degradation pathways of terpenoids or higher fatty acids were one of the most important factors in improving FT quality. With the microbiome, the diversity and functions of microbial flora were analyzed. The high relative abundance function categories were in coincidence with DCs-related metabolic pathways. According to the correlation analysis, Acinetobacter, Sphingomonas and Aspergillus were presumed to be the important contributor, in which Aspergillus was associated with the highest number of degradation products of terpenoids and higher fatty acids. At last, the screened Aspergillus nidulans strain F4 could promote the degradation of terpenoids and higher fatty acids to enhance tobacco flavor by secreting highly active lipoxygenase and peroxidase, which verified the effect of tobacco-microbes on FT quality. Conclusions By integrating the microbiome and metabolome, tobacco-microbe can mediate flavor-related substances to improve the quality of FT after aging, which provided a basis for identifying functional microorganisms for reforming the traditional spontaneous aging.

Odors are considered as one of the most important environmental problems that may adversely influence the quality of life of people affected by their interaction. Due to the multiple sources of emissions, combined with the abundance of chemical compounds classified odor nuisance, new methods of reducing odor emissions are sought while maintaining environmental neutrality. One potential option is to use biochar, a sustainable, carbonized solid product resulting from the thermo-chemical treatment of biomass and/or organic waste. Due to its valuable properties (in particular, high specific surface area, and microporous structure), this material can be used for sorption purposes. Although the issue of using biochar to remove odor emissions is relatively new, in recent years new research directions have been undertaken to determine the sorption efficiency of biochar not only as a direct adsorbent but also in alternative applications. Therefore, this paper aimed to review the most important directions of biochar management in the removal of odor-causing compounds and to highlight the current advances undertaken in this direction. It was distinguished that biochar can enhance odor mitigation by being an additive to compost, a biofiltration medium, a direct adsorbent, a soil additive, a substrate for the production of the odor-absorbing product, a dietary supplement, and a biocover. However, further research is needed to strengthen the range of greater use of biochar in practice.

“…In statistics, redundancy analysis (RDA) is useful for analysing sources of variation of original variables, via correlations between them and typical variables (Yan et al, 2020). Taking the original variable as the dependent variable and the typical variable as the independent variable, and fitting a linear regression model, the corresponding coefficient (R 2 ) of determination is equal to the square of the correlation coefficient between the dependent and independent variables.…”

Paulownia is a well-known, fast-growing tree genus that is widely planted for commercial cultivation in the warm temperate zone of the North China Plain. Fertilization as a standard practice can efficiently increase wood production and tree yield in those Paulownia plantations, but how different fertilization measures might affect soil microbial activity, microbial biomass and metabolic functioning unclear, especially in the subtropics. To fill this knowledge gap, we initiated long-term different fertilization experiments from afforestation, using a completely randomized block design consisting of a control, inorganic fertilizer, microelement-inorganic fertilizer and organic-inorganic compound fertilizer (OIF) treatments in South China's subtropical zone. The results revealed fertilization significantly increased soil enzyme activity and microbial biomass, especially that of urease, invertase, acid phosphatase, as well as the microbial biomass in terms of carbon and nitrogen, all of which increased most significantly in soil under the OIF treatment. The carbon source utilization levels of five carbon substrates under the OIF treatment, namely D-xylose, glucose-1phosphate, D-cellobiose, α-ketobutyric acid and glycogen, were significantly higher than those of the others. From these data, we may reasonably infer that the application of organic fertilizer could offer an effective management practice for use in Paulownia plantations. The five carbon matrices may be the most efficient carbon sources for increasing the abundance of efficient soil microorganisms, improving soil fertility and achieving the sustainable development of Paulownia plantations.
