Chlorophyll-deficient triggers heterotrophic lutein-directed biosynthesis in a novel mutant strain of Chlorella sorokiniana (Chlorophyta): Process characterization and underlying mechanism SCIE
期刊论文 | 2025 , 598 | AQUACULTURE
Abstract&Keyword Cite Version(1)

Abstract :

Chlorella sorokiniana is a promising candidate for lutein production. However, the diversified pigment composition results in a complex and costly extraction process. In this study, a chlorophyll-deficient mutant (MT03) of C. sorokiniana FZU60 was generated by chemical mutagenesis, exhibiting lutein as the primary pigment under heterotrophic conditions with higher content and production than the wild type (WT). Transcriptomic and biochemical composition analyses showed the decreased contents of carbohydrates, lipids, and chlorophylls in MT03, which might lead to the increased biosynthesis of lutein and protein. The inhibition of chlorophyll biosynthesis also triggered the enhanced heme biosynthesis, potentially promoting the functions of cytochrome P450 carotenoid hydroxylases and subsequently facilitating lutein biosynthesis in MT03. Sequencing analysis indicated that the mutation of G1106 to D1106 in MT03 CHLH might hinder the magnesium chelating reaction, leading to the deficiency in chlorophyll biosynthesis. These findings highlight the potential of MT03 as a promising strain for lutein-directed biosynthesis and provide a straightforward and cost-effective approach for enhancing microalgae-based lutein production.

Abstract&Keyword Cite Version(1)

Abstract :

This study aimed to investigate the molecular mechanism of Pseudomonas with varying adhesion capabilities to Tilapia's intestinal mucus influence the spoilage potential of Tilapia. Sodium chloride(NaCl) was used as an environmental factor to regulate Pseudomonas' adhesion ability. After being exposed to 3.5% NaCl stress, the PS01 strain with low adhesion showed an enhancement in adhesion ability, while the LP-3 strain with high adhesion exhibited a decrease. Correspondingly, the expression of critical adhesion genes, such as flgC, fliC, and cheB, was found to be altered. LP-3, with high adhesion ability, was observed to promote a relative increase in Nocardioides and Cloacibacterium in fish intestines. This led to the production of more volatile compounds, including 2-octen-1-ol Z, 2,3-Octanedione, and Eicosane, thus deepening the spoilage of tilapia. LP-3, with reduced adhesion ability after NaCl regulation, showed a diminished capacity to cause fish spoilage. Transcriptomics analysis was used to examine two Pseudomonas strains that exhibited different adhesion abilities, leading to the identification of an adhesion regulatory network involving flagellar assembly regulation, bacterial chemotaxis, quorum sensing, two-component systems, biofilm formation, and bacterial secretion systems. This study identified the Pseudomonas adhesion regulatory pathway and determined 10 key adhesion-related genes.

Abstract&Keyword Cite Version(1)

Abstract :

Two strains of Bacillus subtilis designated YY-10 and BY-2, were isolated from the surface of tobacco and found to be capable of significant lignin degradation. The predominant lignin-degrading enzymes produced by these strains were lignin peroxidase (LiP) and manganese peroxidase (MnP), respectively. A notable distinction was observed in the organoleptic evaluation and volatile flavor compounds, as determined by sensory evaluation and GC-MS analysis. The content of volatile flavor compounds, such as geranylacetone, meglumine trienone B, and meglumine trienone C, was found to be significantly increased in roasted tobacco treated with YY-10. This treatment has been shown to reduce the astringent flavor of the roasted tobacco and improve the aroma, which in turn could improve the quality of the roasted tobacco. Conversely, the quality and aroma levels of the roasted tobacco treated with the crude enzyme solution of the BY-2 strain were reduced. Transcriptome analysis revealed that the expression of genes related to amino acid metabolism, genetic material biosynthesis, and protein synthesis was up-regulated in the YY-10 strain compared with the BY-2 strain, which promoted the biosynthesis of LiP. This study provides a preliminary elucidation of the potential mechanism by which YY-10 enhances the quality of tobacco leaves through lignin-degrading enzyme production, thus establishing a research foundation for the subsequent treatment of waste tobacco raw materials and industrial applications.

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 :

Hongqu rice wine was brewed with glutinous rice as raw material and Hongqu as starter. Monascus and Saccharomyces cerevisiae were the core microorganisms in the brewing system. In this paper, using glutinous rice as the fermentation substrate, Monascus puijmreus, Monascus ruber and Monascus kaoliang were combined with S. cerevisiae to study the effects of different combinations and fermentation modes (simultaneous fermentation and sequential fermentation) on the production of volatile components. A total of 89 volatile flavor compounds were identified from fermented rice wine based on headspace solid phase microextraction-gas chromatography mass spectrometry (HS-SPME-GC-MS). Heat map analysis showed that the combined fermentation of Monascus and S. cerevisiae produced more aroma substances than the pure fermentation of Monascus, and the sequential fermentation produced more aroma substances than the simultaneous fermentation, especially the sequential fermentation of M. purpureas, M. ruber and S. cerevuiae. According to the principal component analysis of volatile flavor components of different Monascus and S. cerevisiae combined fermentation, M. purpureus and M. ruber and S. cerevisiae will produce more volatile flavor components under the sequential fermentation mode, and their flavor compositions were close to each other. Through the analysis of the content difference of volatile flavor components, isobutanol, 1-heptanol, (3Z)-3-nonene-1-ol, 2-tetradecanol, (Z)-5-octene-1-ol, decanal, ethyl caproate, ethyl decanoate, 9 -decenoate, ethyl phenylacetate, ethyl acetate, 1,2 -dimethoxy -4 -vinyl benzene, acridine were the characteristic volatile flavor substances in the combined fermentation products of Monascus and S. cerevisiae. The results of this study could provide a theoretical basis for the improvement of flavor quality and quality control in the industrial production of Hongqu rice wine. © 2024 Chinese Institute of Food Science and Technology.

Abstract :

This paper provides a comprehensive review of antimicrobial peptides (AMPs) derived from Bacillus spp. The classification and structure of Bacillus-derived AMPs encompass a diverse range. There are 89 documented Bacillus-derived AMPs, which exhibit varied sources, amino acid sequences, and molecular structures. These AMPs can be categorized into classes I, Ia, IIa, IIb, IIc, and IId. The synthesis pathway of the AMPs primarily involves either ribosomally synthesized or non-ribosomally synthesized approaches. Additionally, the antimicrobial activity of these AMPs is versatile, targeting bacteria, fungi, and viruses, through disrupting intracellular DNA and the cell wall and membrane, as well as modulating immune responses. Moreover, the Bacillus-derived AMPs demonstrate promising application in the pharmaceutical industry, environmental protection, food preservation, and bio-control in agriculture. The commonly employed strategies for enhancing the production of Bacillus-derived AMPs involve optimizing cultivation conditions, implementing systems metabolic engineering, employing genome shuffling techniques, optimizing promoters, and improving expression host optimization. This review can provide a valuable reference for comprehending the current research status on advancements and sustainable production of Bacillus-derived AMPs.

Abstract :

Bacillus subtilis has been reported to maintain the homeostasis of intestinal flora. In this study, a mouse model of alcoholic liver injury (ALI) was constructed to study the ameliorative effect of B. subtilis C10 on ALI and to further clarify its mechanism of action. Significant correlations between intestinal flora and biochemical indicators of ALI were found by statistical correlation analysis. Supplementation with B. subtilis C10 modulated the equilibrium of gut flora by reducing the population of detrimental bacteria while enhancing the numbers of beneficial microorganisms, which resulted in an improvement in lipid metabolism and oxidative stress in the liver. The results of RT-qPCR showed that B. subtilis C10 intervention regulated the main regulatory factors of liver lipid metabolism (PPAR-alpha, SREBP-1c) and interfered with Nrf-2/Ho-1 signal pathway, which in turn ameliorated alcohol-induced lipid metabolism disorder and liver peroxidation stress. In addition, liver metabonomic analysis showed that B. subtilis C10 intervention reduced the production of harmful metabolites and increased beneficial metabolites in the liver, thereby reversing the metabolic disturbances caused by excessive alcohol consumption. KEGG analysis showed that B. subtilis C10 intervention modulated liver metabolic disorders and accelerated lipid metabolism by regulating glutathione metabolic pathway, purine metabolic pathway, pantothenic acid and CoA biosynthesis pathway, ABC transporter protein pathway, and HIF-1 signaling pathway. Taken together, these findings suggest that B. subtilis C10 ameliorates ALI by modifying the structure of intestinal flora and liver metabolic pathways to attenuate alcohol-exposure-induced liver oxidative damage and lipid metabolism abnormalities.

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.
