Abstract :

红曲酒是以糯米为原料,以红曲作为发酵剂酿造而成的。其中红曲菌和酿酒酵母是酿造体系中的核心微生物。本文以糯米为发酵基质,选用紫色红曲菌、红色红曲菌和高粱红曲菌分别与酿酒酵母菌进行组合发酵,研究不同组合和发酵模式(同步发酵和顺序发酵)对挥发性组分生成的影响。基于顶空固相微萃取-气质联用法,从发酵的米酒中共鉴定出89种挥发性风味化合物。热图分析发现:红曲菌与酿酒酵母组合发酵明显比红曲菌纯菌发酵产生更多的挥发性物质,顺序发酵明显比同步发酵产生更多的挥发性风味物质,尤其是紫色红曲菌、红色红曲菌与酿酒酵母组合的顺序发酵。对不同红曲菌与酿酒酵母组合发酵的挥发性风味组分进行主成分分析,紫色红曲菌和红色红曲菌与酿酒酵母在顺序发酵模式下会产生更多的挥发性风味组分且其风味组成较为接近。挥发性风味组分含量差异分析表明,异丁醇、1-庚醇、(3Z)-3-壬烯-1-醇、2-十四醇、(Z)-5-辛烯-1-醇、癸醛、辛酸乙酯、癸酸乙酯、9-癸烯酸乙酯、苯乙酸乙酯、乙酸苯乙酯、1,2-二甲氧基-4-乙烯基苯等是红曲菌与酿酒酵母组合发酵产物中的特征挥发性风味物质。本研究结果可为红曲酒工业化生产中风味品质的提升与质量控制提供一定的参考数据。

Abstract :

To study the relationship between the diversity of the surface microbial community and tobacco flavor, and to improve tobacco quality using microorganisms. The microbial community composition and diversity of 14 samples of flue-cured tobacco from tobacco-producing areas in Yunnan with varying grades were analyzed by high-throughput sequencing. PICRUSt was used for predicting microbial functions. A strain of Bacillus amyloliquefaciens W6-2 with the ability to degrade pectin was screened from the surface of flued-cured tobacco leaves from Yunnan reroasted tobacco leave. The enzyme preparation was prepared through fermentation and then applied for treating flue-cured tobacco. The improvement effect was evaluated by measuring the content of macromolecule and the changes in volatile components, combined with sensory evaluations. The bacterial communities on the surface of flue-cured tobacco exhibited functional diversity, consisting primarily of Variovorax, Pseudomonas, Sphingomonas, Burkholderia, and Bacillus. These bacterial strains played a role in the aging process of flue-cured tobacco leaves by participating in amino acid metabolism and carbohydrate metabolism. These metabolic activity converted complex macromolecules into smaller molecular compounds, ultimately influence the smoking quality and burning characteristics of flue-cured tobacco. The pectinase preparation produced through fermentation using W6-2 has been found to enhance the aroma and sweetness of flue-cured tobacco, leading to improved aroma, reduced impurities, and enhanced smoothness. Additionally, the levels of pectin, cellulose, and hemicellulose decreased, while the levels of water-soluble sugar and reducing sugar increased, and the contents of esters, ketones, and aldehydes increased, and the contents of benzoic acid decreased. The study revealed the correlation between surface microorganisms and volatile components of Yunnan tobacco leaves, and the enzyme produced by the pectin-degrading bacteria W6-2 effectively improved the quality of flue-cured tobacco.

Abstract :

Objective: To provide a new idea for the development of Bacillus subtilis bio-preservative based on biofilm forming ability. Methods: The hydrophobic ability, self-agglutination rate, co-agglutination rate and biofilm forming ability of Bacillus subtilis were measured. The freshness and volatile flavor of tilapia fillets were measured by Bacillus subtilis. Results: The stronger the biofilm forming ability of Bacillus subtilis, the best preservation effect of tilapia fish. Bacillus subtilis can significantly reduce the content of volatile basic nitrogen in fish meat, so that the TVB-N content of fish was 24.43 mg/100 g on the third day of storage, which was lower than the control group (34.58 mg/100 g). Moreover, the production of alcohol, phenols, esters and acids, such as isoamyl alcohol, phenol, indole, acetic acid and other volatile flavor components in fish was significantly inhibited. At the same time, compared with the biofilm forming ability, the bacteriostatic ability of Bacillus subtilis was not correlated with the fresh-keeping ability. The results showed that the autoagglutination and biofilm forming ability of Bacillus subtilis were most correlated with the preservation ability of tilapia fillets, and could be used as a rapid index for screening Bacillus subtilis for preservation. © 2023 Chinese Institute of Food Science and Technology.

Abstract :

Starch is an essential factor affecting the quality of flue-cured tobacco, and high starch content can affect the sensory quality and safety. Recently, the degradation of macromolecules in tobacco raw materials by using additional microorganisms to improve their intrinsic quality and safety has become a new research hotspot in the tobacco industry. However, the technical maturity and application scale are limited. Our study analyzed the correlation between microbial community composition and volatile components on the surface of tobacco leaves from 14 different grades in Fujian tobacco-producing areas. The PICRUSt software was utilized to predict the function of the microbial community present in tobacco leaves. Furthermore, dominant strains that produced amylase were screened out, and an enzyme solution was prepared to enhance the flue-cured tobacco flavor. Changes in the content of macromolecules and volatile components were determined, and sensory evaluations were conducted to assess the overall quality of the tobacco leaves. The results showed that the dominant bacterial genera on the surface of Fujian tobacco leaves were Variovorax, Sphingomonas, Bacillus, etc. Bacillus was positively correlated with various volatile components, which contributed to the sweet and aromatic flavors of Fujian flue-cured tobacco. The main genetic functions of Fujian flue-cured tobacco surface bacteria were carbohydrate metabolism and amino acid metabolism. After treating flue-cured tobacco with an enzyme preparation prepared by the fermentation of Paenibacillus amylolyticus A17 #, the content of starch, pectin, and cellulose in flue-cured tobacco decreased significantly compared with the control group. Meanwhile, the content of total soluble sugar and reducing sugar was significantly increased, and the volatile aroma components, such as 3-hydroxy--damascone, 2,3-dihydro-3,5-dihydroxy-6-methyl-4 H-Pyran-4-one, ethyl palmitate, ethyl linolenic acid, etc., were significantly increased. The aroma quality and quantity of flue-cured tobacco were enhanced, while impurities were reduced. The smoke characteristics were improved, with increased fineness, concentration, and moderate strength. The taste characteristics were also improved, with reduced irritation and a better aftertaste. In conclusion, Bacillus, as the dominant genus in the abundance of bacterial communities on tobacco surfaces in Fujian, had an essential impact on the flavor of tobacco leaves by participating in carbohydrate metabolism and finally forming the unique flavor style of flue-cured tobacco in Fujian tobacco-producing areas. Paenibacillus amylolyticus A17 #, a target strain with amylase-producing ability, was screened from the surface of Fujian flue-cured tobacco. The enzyme preparation, produced by the fermentation of Paenibacillus amylolyticus A17 #, was utilized to reduce the content of macromolecules, increase the content of water-soluble total sugar and reducing sugar, and produce a variety of crucial volatile aroma components, which had a significant improvement on the quality of tobacco leaves.

Abstract :

In this study, antibacterial substances were extracted and identified from the mycelia of Eurotium cristatum FS-1, and evaluated for antibacterial activity against Pseudomonas putida LP-3. The underlying mechanism was investigated by microscopic observations, LP-3 cell content analysis, and metabolomic analysis. The results showed that the half maximal inhibitory concentration (IC50) of the ethyl acetate extract (FSEAE) from the mycelia of Eurotium cristatum FS-1 on P. putida LP-3 (1 × 104 CFU/mL) was 8 mg/mL. As observed by scanning electron microscopy (SEM), FSEAE destroyed the cell membrane of P. putida LP-3. The K+ content in the culture supernatant of P. putida, the activity of oxidative stress enzymes in the cell metabolic pathway (superoxide dismutase, glutathione peroxidase, and catalase) and the content of malondialdehyde (MDA) were measured, showing that the antibacterial effect of FSEAE mainly in the logarithmic growth period of P. putida LP-3 (8–16 h). Non-targeted metabonomics was used to analyze FSEAE treated samples and control samples (treated by dimethyl sulfoxide), and a total of 124 metabolites were obtained, of which 30 metabolites were significantly different between the two groups. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis showed that FSEAE affected the growth and metabolism of P. putida mainly by interfering with the tricarboxylic acid cycle. The results from this study can provide a theoretical reference for the development and utilization of Saccharomyces coronatus and its metabolites. © 2023 Chinese Chamber of Commerce.

Abstract :

Tobacco leaves need to aged under certain temperatures and humidity for 1 to 3 years. Natural aging, also called fermentation, is a slow process. This article explores the correlation between microorganisms on the surface of flue-cured tobacco and key flavor substances during this process. High-throughput sequencing was used to characterize the composition of bacterial and fungal communities on the surface of flue-cured tobacco from Hunan, Liaoning, Guizhou, Shandong, Yunnan, Fujian, Brazil, and Zimbabwe. Gas chromatography-mass spectrometry (GC-MS) was employed to determine the flavor substances in flue-cured tobacco and correlation analysis between microbial diversity and flavor substances was performed. The function and abundance of key enzymes involved in the degradation of macromolecules on the surface of flue-cured tobacco were predicted using PICRUSt and FUNGuild. Different flavor styles of flue-cured tobacco possessed different flora structures, and the abundance of the genus Bacillus was high and significantly positively correlated with the content of the main flavor substances-carotenoid and cembranoid degradation products (p < 0.05). The content of the Enterobacter genus was higher in light-flavor style flue-cured tobacco and significantly negatively correlated with the above substances (p < 0.05). Among the fungal genera, Wallemia exhibited a significantly positive correlation with phenylacetic acid, palmitic acid, and & alpha;-ionol (p < 0.05). The abundance of the macromolecule-degrading enzymes in the bacterial community was generally higher than in the fungal community, especially the enzymes that hydrolyzed, transferred, and isomerized starch, protein, and cellulose. Classifying the tobacco leaves according to the flavor style revealed that the expression levels of a series of enzymes acting on pectin hydrolysis and cleavage and laccase were higher in strong-flavor flue-cured tobacco. This study explored the microorganisms related to the key substances of flue-cured tobacco and provided a theoretical basis for using microorganisms to improve the flavor.

Abstract :

Aquatic products are highly susceptible to spoilage caused by adherence of spoilage bacteria during storage, so it is crucial to develop new microecological preservatives. The probiotic B. subtilis can achieve potential preser-vation effects by adhering to the fish gut to regulate the amount of probiotic colonization in the flora. Here, we demonstrated the surface adhesion characteristics of B. subtilis and the mechanism of adhesion-associated gene -mediated adhesion; the regulation of B. subtilis adhesion ability by nitrogen and carbon sources, and the application of tilapia preservation. Our results revealed 10 B. subtilis adhesion-related genes, among which ni-trogen sources up-regulate the adhesion genes hag and motA, carbon sources up-regulate sinR and fliG. Based on flagellum-associated high adhesion strain C6 and high adhesion regulation of B. subtilis C6_H allowed the abundance of probiotic bacteria Bacillus, Rhodobacteraceae to increase, attenuate the content of spoilage flavor substances such as 1-Octen-3-ol, 15-Crown-5 and maintain the freshness of tilapia. The results helped to reveal the adhesion mechanism of B. subtilis and to develop and apply microecological preservatives with high quality adhesion ability.

Abstract :

Shewanella putrefaciens is a typical spoilage bacteria organism in seafood. The adhesion ability of three S. putrefaciens strains (HR-15, JR-18, HC-71) isolated from putrefied tilapia were evaluated by mucus adhesion in vitro and intestinal adhesion in vivo. The results of the spoilage of the inoculated fish fillets and spoilage of the refrigerated fish both showed that the adhesion ability of S. putrefaciens was positively correlated with the spoilage ability. High-throughput sequencing and GC-MS results showed that S. putrefaciens with high adhesion ability also significantly changed the intestinal flora of fish, causing an increase in the intestinal bacteria such as Plesionomas, Macellibacteroides, Acinetobacter, and Legionella, which then led to the increase in volatile substances such as low-grade aldehydes, alcohols, and ketones in the fish, serious fatty acid oxidation, and excitement of the fishy smell.
