Synergistic groups were formed by 1:1 and labeled as G1 (<em>L. plantarum</em> MZ707748.1 and <em>L. plantarum</em> MZ729681.1), G2 (<em>W. confusa</em> MZ735961.1 and <em>L. plantarum</em> MZ727611.1), G3 (<em>L. plantarum</em> MZ729681.1, <em>W. confusa</em> MZ735961.1, and <em>Lactobacillus acidophilus</em> La-14), G4 (all above mentioned probiotics). Rats were gavage-fed with probiotics according to their colony-forming unit (CFU). The experiment was carried out for 35 days. The bacteria were re-isolated from the gut and identified by biochemical tests which confirmed the administration and re-isolation of different <em>Lactobacillus</em> strains from the gut. Molecular characterization was done through 16S rRNA by using universal primers. After sequencing eight <em>Lactobacillus</em> strains were identified. Histopathology of rats’ intestines was done, and different parameters were examined. Villus height, crypt height, crypt width, mucosa, and sub-mucosa of jejunum were significantly (p = 0.00) increased in the G3 synergetic probiotic group compared to 0-day and negative control. However, the villus width showed non-significant (p &gt; 0.05) variations in both genders. Mucosa tunic, muscle tunic, total wall, and crypt depth were significantly increased (p = 0.00) in the G4 group of medial colon. The study concluded that gut morphology improves as probiotics adhere better to the intestinal epithelium, excluding pathogens, reducing inflammation, enhancing nutrient absorption, and stimulating mucosal growth. This results in improved villus structure and gut wall integrity.</div></div>","PeriodicalId":52676,"journal":{"name":"Current Research in Biotechnology","volume":"9 ","pages":"Article 100271"},"PeriodicalIF":3.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143136459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been demonstrated that MFC directly converts organic matter present in wastewater into energy. The present study uses a cell design based on simple plate geometry, carbon felt electrodes and Nafion117 as proton exchange membrane separating the anode and cathode chambers. The anode was then modified with heat and acid treatment and PEM was treated with PVDF to improve the performance of the cell. Synthetic dairy wastewater with initial COD of 2412 mg/l was used to test the operation of stack consisting of four cells which were hydraulically connected in series. The stack operated with continuous flow of wastewater. COD removal of the feed water was tested in successive cells to achieve the permissible limits for safe discharge of the effluent. COD decreased from 2412 mg/l to 126 mg/l after the fourth cell. For the power output each cell was treated individually. The power density of each cell was directly proportional to the COD of the influent. The power density of the first cell that has the highest COD was measured at 77.9 mW/m², which is two times that for the cell with unmodified anode and membrane. For the first cell COD removal was the highest at 57 % and 2.6 times more than the cell with the unmodified anode and membrane. These results suggest that targeted modifications to the anode and membrane can significantly boost the MFC performance both in terms of COD removal and corresponding power output. Secondly, up to 93.66 % COD removal may be achieved by four cells hydraulically connected in series. The paper offers some insights for stacking options for implementing at scale up of the MFC technology for wastewater treatment plants.</div></div>","PeriodicalId":52676,"journal":{"name":"Current Research in Biotechnology","volume":"9 ","pages":"Article 100278"},"PeriodicalIF":3.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143478906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its increasing prevalence has led to a global epidemic, emphasizing the urgent need for innovative and effective treatment strategies. This study aims to explore the potential of CRISPR/Cas9-mediated gene editing to enhance UCP1-dependent thermogenesis, offering a novel approach to obesity management. Uncoupling protein 1 (UCP1), primarily located in the inner mitochondrial membrane of brown adipose tissue (BAT), plays a crucial role in thermogenesis and energy expenditure. By converting stored energy into heat, UCP1 activation enhances calorie burning, helping to regulate body temperature and mitigate obesity-related health risks. Recent advancements in genome editing technologies, particularly CRISPR/Cas9, provide a precise method to modify genes involved in UCP1 expression and activity. This approach holds significant promise for sustainable obesity management by enhancing metabolic efficiency and energy expenditure. This study examines the feasibility of using CRISPR/Cas9 to target the UCP1-dependent thermogenesis pathway for obesity treatment. It explores the mechanisms of CRISPR/Cas9, the role of UCP1 in energy regulation, and potential strategies to enhance thermogenic activity. Our findings highlight the promise of CRISPR-based interventions in metabolic regulation.

The main parameters for comparison included the geographical location, unit production cost, and environmental impact categories. The results show that the economic and environmental performances are highly variable among the different feedstocks and their processing routes, also depicting evident tradeoffs.
