Alcanivorax borkumensis SK2, a marine bacterium with superior hydrocarbon-degrading capabilities, emerges as a promising agent for bioremediation. This study identified an economical growth substrate for A. borkumensis SK2 and led to highly viable cell powder formulations for effective applications in contaminated marine environments. Various non-hydrocarbon substrates were evaluated to replace the costly sodium pyruvate, revealing that canola oil and sunflower oil gave biomass levels (optical density) four times higher than sodium pyruvate (20 ± 2 and 20 ± 1, compared to 4.6 ± 0.4, respectively). Freeze-drying and spray-drying approaches were investigated to produce a viable cell formulation. Two screening campaigns of potential freeze-drying cryoprotectants showed that the proprietary blend of Proventus Bioscience Inc. (Proventus) and 0.5 M glutamate ensured the highest viability, with 2 ± 1×10¹⁰ and 1.1 ± 0.3 × 10¹⁰ CFU/g, after the first screening, and 1.0 ± 0.5 × 10¹⁰ and 6 ± 2 × 10⁹ CFU/g after the second screening. Differential scanning calorimetry (DSC) analysis demonstrated a 9%-15% reduction in ice formation with cooling rates from 5 to 10°C/min. Glutamate reduced ice formation by 5%-9% compared to Proventus' solution. To promote cell viability during A. borkumensis SK2 freezing and freeze-drying, the best product temperatures were determined to be -65°C with 0.5 M glutamate and -59°C with Proventus' blend. Spray-drying resulted in cell powders with a viability up to 1.0 ± 0.7 × 10⁵ CFU/g, considerably lower than the levels obtained by freeze-drying, indicating some potential but also the need for further research and optimization.</p>","PeriodicalId":9274,"journal":{"name":"Biotechnology and applied biochemistry","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although TIGAR (TP53-induced glycolysis and apoptosis regulator), a key glycolytic regulator, has been implicated in various pathological processes, its role in AP remains unexplored. In this study, we established an AP mouse model through intraperitoneal injection of high-dose caerulein. AP mice exhibited downregulated pancreatic TIGAR expression accompanied by enhanced glycolysis. In vitro, primary pancreatic acinar cells were stimulated with LPS to mimic the inflammatory microenvironment. TIGAR overexpression effectively mitigated LPS-induced reductions in cell viability, inflammatory cytokine expression, reactive oxygen species (ROS) production, and glycolytic activation. Notably, LAMP2 (lysosome-associated membrane protein 2) knockdown abolished the protective effects of TIGAR against LPS-induced ROS, inflammation, and glycolytic flux. Mechanistically, TIGAR suppressed LPS-induced glycolytic activation by upregulating LAMP2 expression, thereby inhibiting PI3K/Akt pathway activation. Consistently, the glycolytic inhibitor 2-DG reversed the detrimental effects of TIGAR knockdown on cell viability and inflammatory responses. Furthermore, both preventive and therapeutic AAV8-TIGAR administration attenuated AP progression in mice.

This study aims to design a broad-spectrum vaccine against Nocardiosis. We used subtractive proteomics and vaccinomics approaches to identify vaccine candidates to design an epitope-based vaccine against Nocardiosis. Four proteins in the outer membrane and extracellular regions were shortlisted on the basis of immunogenic parameters. T- and B-cell epitopes were predicted on the basis of IC<sub>50</sub> < 200 nM, and a multi-epitope vaccine construct was designed using six overlapping CTL, HTL, and B-cell epitopes conjugated by appropriate linkers. A highly immunogenic adjuvant was integrated at the N-terminus of the multi-epitope vaccine to stimulate a robust immune response. The tertiary structure of the vaccine construct was predicted and validated with the 96% residues in the favorite region of the Ramachandran plot and a Z-score of -4.76. The proposed vaccine exhibited strong immunological and physicochemical features. High docking scores and strong binding energies of approximately -1051.9 to -1274.5 kcal/mol with human immune receptors ensured that the designed vaccine construct could induce potential immunogenic responses in the host immune system. The efficacy of the vaccine was evaluated by the immune simulation to determine the potential of the vaccine to simulate innate and adaptive immunity with the development of long-lasting memory immune cells. The molecular dynamic simulation of a 100 ns study was conducted to determine the structural stability and molecular function of the designed vaccine in the cellular microenvironment. In silico restriction cloning analysis determined the successful expression of the engineered vaccine construct in Escherichia coli plasmid with a size of 6323 bp.

In this study, the effect of PDI, KAR2, HAC1, and ERO1 co-expression on Geobacillus stearothermophilus lipase production in P. pastoris was investigated. The chaperones were co-expressed under the regulation of the GAP promoter in clones with different lipase production levels (LPS#2 and LPS#8). Results showed that lipase-PDI co-expression clones have the highest activity. The effect of the other chaperones had varying effects for LPS#2 and LPS#8 clones. LPS#2-PDI and LPS#8-PDI were further analyzed to determine the effect of dimethyl sulphoxide (DMSO). Different concentrations (0.5%, 1%, and 2%) of DMSO were tested. The highest activity was obtained with approximately 1.5-fold activity in the LPS#8-PDI clone with 0.5% and 1% DMSO concentration levels. Comparison of the fermentation kinetic parameters revealed that the activity level of 56.54 U/mL provided with LPS#8 increased to 73.84 U/mL in the LPS#8-PDI clone with PDI co-expression, and when PDI co-expression was combined with DMSO conditions (0.5%), it reached 114.46 U/mL.

USP46 mRNA levels in clinical prostate cancer samples were analyzed using the online The University of Alabama at Birmingham Cancer Data Analysis Portal (UALCAN) database. The expression of USP46 mRNA and protein was analyzed using RT-PCR and immunoblotting techniques.

USP46 mRNA expression was significantly lower in prostate cancer cells compared to that in normal cells. Overexpression of USP46 significantly reduced cell proliferation, as shown by decreased cell viability and fewer colonies. Mechanistic studies demonstrated that USP46 interacted with and stabilized BECN1, supported by findings showing that USP46 overexpression increased BECN1 levels and delayed its degradation in prostate cancer cells treated with cycloheximide. Additionally, knockdown of BECN1 and inhibition of autophagy partially restored cell proliferation in USP46-overexpressing cells.

Plants produce an increased number of antioxidants as part of their secondary metabolism as a direct response to the stress.
