Abstract
Itaconate is a promising platform chemical with broad applicability, including the synthesis of poly(methyl methacrylate). Most studies on microbial itaconate production entail the use of crop-based feedstock, which imposes constraints due to its limited supply. Brown macroalgae have recently gained attention as next-generation biomass owing to their high biomass productivity and carbohydrate content and amenability to mass production. Therefore, the use of macroalgae for itaconate production warrants exploration. In this study, the direct production of itaconate from brown macroalgae was demonstrated using engineered Vibrio sp. dhg, which has emerged as an efficient platform host for brown macroalgal biorefineries. Specifically, to enhance production, cis-aconitate decarboxylase (Cad) from Aspergillus terreus was heterologously expressed and isocitrate dehydrogenase (icd) was deleted. Notably, the resulting strain, VIC, achieved itaconate titers of 2.5 and 1.5 g/L from a mixture of alginate and mannitol (10 g/L of each) and 40 g/L of raw Saccharina japonica (S. japonica), respectively. Overall, this study highlights the utility of brown macroalgae as feedstock, as well as that of Vibrio sp. dhg as a platform strain for improving itaconate bioproduction.

Inflammatory reaction and immune response of half-smooth tongue sole (Cynoglossus semilaevis) after infection with Vibrio anguillarum. FISH & SHELLFISH IMMUNOLOGY 2023; 141:109043. [PMID: 37673387 DOI: 10.1016/j.fsi.2023.109043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Revised: 08/25/2023] [Accepted: 08/26/2023] [Indexed: 09/08/2023]
Abstract
Frequently occurred bacterial diseases have seriously affected the aquaculture industry of half-smooth tongue sole (Cynoglossus semilaevis). Notably, vibriosis, with Vibrio anguillarum as one of the causative pathogens, is the most severe bacterial disease with severe inflammatory response of the host, leading to high mortality rates. In the present study, we explored the relationship between bacterial concentrations and host mortality, inflammatory reaction, and immune response in half-smooth tongue sole after infection with V. anguillarum at different concentrations (Treatment 1, 6.4 × 105 CFU/mL; Treatment 2, 6.4 × 106 CFU/mL). The mortality of Treatment 2 (77.5%) was significantly higher than that of Treatment 1 (10%), corresponding with bacterial concentrations. Although the number of deaths varies, intensive deaths were observed within 24 h post infection (hpi) in both bacterial concentration groups. Histopathological analyses revealed that fish tissues were most severely damaged at 24 or 48 hpi, and Treatment 2 was more severe than Treatment 1. A qRT-PCR-based detection method with virulence factor gene empA was established to quantify the bacterial loads in various tissues, and the bacterial loads were the highest at 24 hpi in Treatment 2, and at 48 hpi in Treatment 1. Additionally, the expression levels of complement genes (C5a, C3, C5, and C6), inflammatory factors (IL-1β, TNF-α, and IL-10), and other immune-related genes (jak2, NF-κB1, stat3, and tlr3) were increased in various tissues after infection in both treatment groups, with most genes being most expressed at 24 or 48 hpi, and expression levels of inflammatory factors in Treatment 2 were higher than those in Treatment 1. Moreover, the expression of C5a was positively correlated with that of proinflammatory cytokines in both bacterial concentration groups. According to the results of this study, 24-48 hpi was a key node for early vibriosis detection and intervention. Compared with the low mortality of Treatment 1, the mass death of fish in Treatment 2 was suggested to be caused by uncontrolled excessive inflammatory reaction induced by the overactivation of complement system, especially C5a. We believe these results could provide theoretical basis for prevention, evaluation, and treatment of vibrio disease in tongue sole aquaculture, and lay a solid foundation for future functional analyses.

Comparative Analysis of Transcriptome and Proteome Revealed the Common Metabolic Pathways Induced by Prevalent ESBL Plasmids in Escherichia coli. Int J Mol Sci 2023; 24:14009.

Abstract
Antibiotic resistance has emerged as one of the most significant threats to global public health. Plasmids, which are highly efficient self-replicating genetic vehicles, play a critical role in the dissemination of drug-resistant genes. Previous studies have mainly focused on drug-resistant genes only, often neglecting the complete functional role of multidrug-resistant (MDR) plasmids in bacteria. In this study, we conducted a comprehensive investigation of the transcriptomes and proteomes of Escherichia coli J53 transconjugants harboring six major MDR plasmids of different incompatibility (Inc) groups, which were clinically isolated from patients. The RNA-seq analysis revealed that MDR plasmids influenced the gene expression in the bacterial host, in particular, the genes related to metabolic pathways. A proteomic analysis demonstrated the plasmid-induced regulation of several metabolic pathways including anaerobic respiration and the utilization of various carbon sources such as serine, threonine, sialic acid, and galactarate. These findings suggested that MDR plasmids confer a growth advantage to bacterial hosts in the gut, leading to the expansion of plasmid-carrying bacteria over competitors without plasmids. Moreover, this study provided insights into the versatility of prevalent MDR plasmids in moderating the cellular gene network of bacteria, which could potentially be utilized in therapeutics development for bacteria carrying MDR plasmids.

Abstract
Vaccines are safe and efficient in controlling bacterial diseases in the aquaculture industry and are in line with green farming. The present study develops a previously unreported approach to prepare a live-attenuated V. alginolyticus vaccine by culturing bacteria in a high concentration of magnesium to attenuate bacterial virulence. Furthermore, metabolomes of zebrafish immunized with the live-attenuated vaccines were compared with those of survival and dying zebrafish infected by V. alginolyticus. The enhanced TCA cycle and increased fumarate were identified as the most key metabolic pathways and the crucial biomarker of vaccine-mediated and survival fish, respectively. Exogenous fumarate promoted expression of il1β, il8, il21, nf-κb, and lysozyme in a dose-dependent manner. Among the five innate immune genes, the elevated il1β, il8, and lysozyme are overlapped in the vaccine-immunized zebrafish and the survival from the infection. These findings highlight a way in development of vaccines and exploration of the underlying mechanisms.

Abstract
Fish diseases are often caused either by bacteria, viruses, fungi, parasites, or a combination of these pathogens. Of these, bacterial fish diseases are considered to be a major problem in the aquaculture industry. Hence, the prevention of such diseases by proper vaccination is one of the integral strategies in fish health management, aimed at reducing the fish mortality rate in the aquaculture farms. Vaccination offers an effective yet low-cost solution to combat the risk of disease in fish farming. An appropriate vaccination regime to prevent bacterial diseases offers a solution against the harmful effects of antibiotic applications. This review discusses the role of live-attenuated vaccine in controlling bacterial diseases and the development of such vaccines and their vaccination strategy. The current achievements and potential applications of live-attenuated and combined vaccines are also highlighted. Vaccine development is concluded to be a demanding process, as it must satisfy the requirements of the aquaculture industry.
