Tobacco production is a significant industry worldwide, and the quality of tobacco leaves is a crucial factor in determining the taste and quality of cigarettes. The use of synthetic fertilizers in tobacco production has been the traditional method for providing nutrients to tobacco plants. However, the use of synthetic fertilizers can have harmful effects on human health and the environment. In recent years, organic fertilizers have emerged as an alternative method that offers numerous benefits, including improved soil quality, enhanced nutrient content in tobacco leaves and reduced harmful chemicals. This paper aims to explore the impact of applying organic fertilizers to tobacco leaves on the quality and taste of cigarettes and to compare the benefits of organic fertilizers with those of synthetic fertilizers. The impact is analyzed by applying organic fertilizers to tobacco leaves on the taste and quality of cigarettes, sensory evaluation tests, and chemical analysis. These sensory evaluation test can provide data on the flavor, aroma, and chemical composition of cigarettes produced with organic and synthetic fertilizers. Then hypothesis testing is conducted to identify the significance of the organic fertilizers in improving the quality and taste of cigarettes produced from tobacco leaves grown with organic fertilizers versus synthetic fertilizers.

The recycling use of wood sawdust to process composite boards has received much attention in recent years. To avoid the use of chemical adhesives, natural cellulose-based materials were often used as adhesives to combine wood sawdust. Rather than utilizing nanocellulose, the report herein describes a method to prepare a robust composite board that is based on microfibrous cellulose, which is a low-cost commercial product. To effectively cross-link wood sawdust and microfibrous cellulose, phosphoric acid-activated glutaraldehyde was used as catalyst. Compared to its uncross-linked counterpart, the modulus of elasticity and modulus of rupture of the composite board that had been cross-linked by glutaraldehyde and phosphoric acid were significantly strengthened to 3.45±0.06 GPa and 36.5±3.5 MPa, respectively. Moreover, the moisture resistance of the cross-linked composite board was also enhanced. After soaking in water for 24 h, the mass swelling ratio and thickness swelling ratio of cross-linked composite board had only changed 49% and 21%, respectively. These performances even exceeded that of composite board prepared from nanocellulose. The method described in this work may have applications in commercial processing and the recycling of wood sawdust.

In this work, an n-octadecylamine functionalized mesoporous carbon nanocomposite (ODA-MPC) was synthesized, and its novel application was demonstrated by utilizing it as a sorbent in matrix solid-phase dispersion (MSPD) of nine pesticide residues identified by gas chromatography-mass spectrometer. Here, the protection of the sorbent by the mesoporous fiber membrane enabled it to process complex aqueous matrices and made it advantageous to be used in MSPD. The results confirmed the excellent ability of ODA-MPC to remove matrix interferences and reduce matrix effects compared to the traditional solid phase extraction. In particular, the recoveries were 85.0–95.8% (n = 3) with relative standard deviations less than 5%. Additionally, nine pesticide residues in vegetables and fruit were satisfactorily extracted and detected.

This study aimed to determine the structural characteristics and adsorption capacities of a novel activated carbon prepared from passion fruit by-product. Passion fruit peel was carbonized and structurally modified using phosphoric acid-potassium hydroxide reagent before carbon activation. Industrial-activated carbon was used as a control sample. The surface functional groups and adsorption capacities of the activated carbon samples were determined. The results showed that the chemical-modified activated carbon had anhydride and carboxylic acid as the main functional groups on the carbon surface, together with several conformations of the hydroxyl group. These hydroxyl confirmations were in alkoxy and carboxylate forms but not phenoxy. The peel-based activated carbon had a smoother carbon surface with multiple micropores, whereas the carbon surface of industrial activated carbon was rough with multiple meso- and macropores. The methylene blue adsorption capacity (0.1 mg/mL methylene blue) of the peel-based activated carbon (99.97±0.01%) was comparable to the industrial activated carbon (100.00±0.01%). But the peel-based activated carbon had better cholesterol and albumin adsorption capacities than the industrial activated carbon. Since activated carbon prepared from the fruit peel has better adsorption capacities of cholesterol and other chemicals in liquid foods, it can replace the wood-based activated carbon in food and pharmaceutical applications.

The present work studied the anticancer effects of four honey varieties on human cells by studying some physical parameters, hydrogen peroxide content, catalase, glucose oxidase, and microbial activities. Honey samples were (nigella sativa, moringa, sidr, pumpkin), which were coded as NS, MO, SI, and PU honey, respectively. The tested bacterial isolates Staphylococcus aureus, and Enterococcus faecalis were used for microbial activities. Two types of human cells, breast, and colon adenocarcinoma cell lines were used for anticancer properties. SI Honey samples showed the lowest value for electrical conductivity 3.19 μS cm−1. PU Honey samples recorded the highest value for hydrogen peroxide contents 1582.05 μM, while SI Honey reported a similar trend of 1501.51 μM. The values of catalase enzyme activity ranged from 2.78 U/g in SI Honey to 3.91 U/g in MO Honey. Glucose oxidase activity ranged from 4.12 U/g in NS Honey samples to 10.55 U/g in MO Honey. The highest antibacterial activity was detected by SI Honey with a zone of inhibition value of 14.99 mm against Staphylococcus aureus. PU Honey was the best to inhibit the microbial loud of Enterococcus faecalis 7.93 mm. SI Honey was the most effective against breast adenocarcinoma cells (IC50 66.15 μg/mL), on the same trend MO Honey was the most effective against colon adenocarcinoma cells (IC50 45.13 μg/mL). While NS Honey recorded lower efficiency against both breast and colon adenocarcinoma cancer cells IC50 95.13 μg/mL and IC50 87.66 μg/mL, respectively. The control detected the lowest cytotoxic effects on both breast and colon adenocarcinoma cancer cells IC50 112.33 μg/mL and IC50 203.97 μg/mL, respectively.

There are fungal communities in fermented grains and high-temperature Daqu of Danquan Baijiu, which had an important effect on Baijiu production. As a saccharifying and fermenting material, to a great extent, Daqu determines Baijiu flavour. However, in high-temperature Daqu “dqjq_ck” and “dqjqcp” (after fermentation for 45 d, 135 d) and fermented grains dqjp3 originated from Danquan distillery, fungal communities remain unclear. Therefore, this study analyzed fungal communities by high-throughput sequencing. Their fungal communities mainly included Ascomycota at phylum level. The most abundant fungal genera were Aspergillus, Issatchenkia and Zygosaccharomyces in dqjq_ck, dqjqcp, dqjp3, respectively. The dominant genera included Aspergillus (96.21%), Thermomyces (2.13%) in dqjq_ck. The dominant genera contained Issatchenkia (48.29%), Millerozyma (14.53%), Thermoascus (12.17%), Aspergillus (8.80%), Hyphopichia (3.28%), Rhizomucor (3.17%), Lichtheimia (2.62%), Thermomyces (2.27%), Monascus (1.37%) in dqjqcp. The dominant genera had Zygosaccharomyces (68.48%), Monascus (15.18%), Aspergillus (6.97%), Cladosporium (1.12%) in dqjp3. The main fungi included Aspergillus, Zygosaccharomyces, Issatchenkia, Monascus, Millerozyma, Thermoascus, Thermomyces, Hyphopichia, Rhizomucor, Lichtheimia and Cladosporium in three samples. The fungal succession of three samples were revealed in three key stages of Danquan Baijiu production. This paper will lay the basis for screening outstanding fungi to enhance Danquan Baijiu quality in near future.

Tobacco growth monitoring and yield estimation are very important for tobacco planting control and allocation. However, traditional tobacco yield estimation models have not considered the light energy utilization, carbon cycle, and ecological processes, resulting in the mechanisms poorly explained and the reduced monitoring accuracy. To address these limitations, a tobacco yield remote sensing monitoring model based on ecological process and carbon cycle was proposed. The model couples the Carbon Exchange between Vegetation, Soil, and Atmosphere (CEVSA) ecosystem process model and the global production efficiency model (GLO-PEM), to simulate effective solar radiation and tobacco light energy utilization, stress effects of surface air temperature, water vapour pressure deficit and photosynthetic effective radiation. Then the tobacco gross primary production (GPP), net primary productivity (NPP), tobacco biomass were estimated. Finally, the tobacco yield estimation model based on the correlation between tobacco yield and NPP was proposed. The results showed that there was a significant correlation (correlation= 0.94) between NPP and tobacco leaves weight at 99% confidence level, and the yield estimated by the remote sensing monitoring model was in good agreement with the measured results, with errors of Class I, II, III were 9.644%, 4.316%, and 8.495% respectively. In conclusion, the proposed model can be used to estimate tobacco yield, support decision-making of tobacco planting plan, and strengthen purchasing management.

The contents and correlation of various mineral elements in soil and roots, stems and leaves of Fritillaria hubeiensis were analyzed and evaluated to supply basis for diagnosis of soil mineral nutrition and rational fertilization of Fritillaria hubeiensis. The contents of Phosphorus, potassium, calcium, magnesium, iron, zinc, manganese and copper were tested by the inductively coupled plasma, and the results were analyzed by SPSS11.5 software. The total contents of manganese, phosphorus, potassium, calcium and magnesium in soil and roots, leaves and stems of Fritillaria hubeiensis were different with different cultivation bases. The order of Fe and Cu contents was root > leaf > stem. The distribution of Zn showed a trend of “root > stem > leaf.” Between potassium content of soil and root, it was a significant positive correlation. But there was a significant negative correlation between Zinc content of soil and root. The total contents of calcium and iron were positively correlated between roots and stems. The total contents of Phosphorus, potassium, magnesium and copper were positively correlated among stems and leaves, while the contents of Mn were positively correlated. Therefore, Fritillaria hubeiensis mainly regulates the amount of mineral nutrients through selective absorption.

Fat is the third largest substance in rice seeds, and its content has a great impact on rice cooking, taste and storage qualities. However, few genes related to seed fat content have been cloned, which seriously restricts the application of fat traits in high-quality rice breeding. ‘Goudang 3’ is a representative aromatic rice landrace of Guizhou He, a characteristic rice species resource in Guizhou Province, China. It has the advantages of high fat content, rich flavor, soft and glutinous taste, etc. In this work, to address this issue, from a high-fat content rice variety, Goudang 3, and a low-fat content rice variety, Huazhan, a 148 recombinant inbred lines (RILs) population were derived. A high-density genetic map with 4063 Bin Markers covering 12 chromosomes were constructed through simplified genotyping-by-sequencing (GBS) technology. In combination with fat content, a brown rice fat content quantitative trait loci (QTL) qCFC3 was mapped within the 492 kb interval on chromosome 3. The qCFC3 was consistent with the previous reporting site, and no cloned fat content-related genes have been reported. LOC_Os03g13630 was identified. In conclusion, these QTL and candidate gene can be used for improving rice quality and can lay a foundation for further cloning and functional analysis.

It has the advantages of high fat content, rich flavor, soft and glutinous taste, etc. In this work, to address this issue, from a high-fat content\u0000 rice variety, Goudang 3, and a low-fat content rice variety, Huazhan, a 148 recombinant inbred lines (RILs) population were derived. A high-density genetic map with 4063 Bin Markers covering 12 chromosomes were constructed through simplified genotyping-by-sequencing (GBS) technology. In combination\u0000 with fat content, a brown rice fat content quantitative trait loci (QTL) qCFC3 was mapped within the 492 kb interval on chromosome 3. The qCFC3 was consistent with the previous reporting site, and no cloned fat content-related genes have been reported. LOC_Os03g13630 was\u0000 identified. In conclusion, these QTL and candidate gene can be used for improving rice quality and can lay a foundation for further cloning and functional analysis.","PeriodicalId":15157,"journal":{"name":"Journal of Biobased Materials and Bioenergy","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47652811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acidified oil is characterized as high acid value. Hence, deacidification is indispensable in biodiesel production from acidic oil. Heterogeneous catalysts have many advantages over homogeneous counterparts in deacidification of acidic oil. Therefore, in the present work, sulfonated mesoporous silica (SMS) was prepared and characterized, followed by the systematical investigation on the effect of reaction variables on the deacidification rate (DR). Furthermore, response surface methodology (RSM) was employed to optimize the reaction parameters. Results showed that the optimal studied reaction variables for the deacidification process were as follows: reaction temperature 65 °C, methanol to oleic acid ratio 35:1, catalyst loading of 2%, in which, deacidification rate of 97.78% could be achieved. DR of 62.52% could still be obtained after catalyst had been used for four consecutive cycles. Finally, significant enhancement of DR could be achieved by using calcined kaolin to assist the deacidification of acidified oil with high water content, indicating that there is great potential in deacidification of acidic oil catalyzed by SMS with the assistance of calcined kaolin for biodiesel production.
