An emerging alternative to conventional injectable vaccines is edible vaccines, which promise increased delivery efficiency while maintaining vaccine effectiveness. One of the most promising platforms for edible vaccines is duckweeds, due to their high growth rate, ease of transformation, and excellent nutritional content. This review explores the potential, feasibility, and advantages of using duckweeds as platforms for edible vaccines. Duckweeds have proven to be superb feed sources, as evidenced by numerous improvements in both quantity (e.g., weight gain) and quality (e.g., yolk pigmentation). In terms of heterologous protein production, duckweeds, being plants, are capable of expressing proteins with complex structures and post-translational modifications. Research efforts have focused on the development of duckweed-based edible vaccines, including those against avian influenza, tuberculosis, Newcastle disease, and mastitis, among others. As with any emerging technology, the development of duckweeds as a platform for edible vaccines is still in its early stages compared to well-established injectable vaccines. It is evident that more proof-of-concept studies are required to bring edible vaccines closer to the current standards of conventional vaccines. Specifically, the duckweed expression system needs further development in areas such as yield and growth rate, especially when compared to bacterial and mammalian expression systems. Continued efforts in this field could lead to breakthroughs that significantly improve the resilience of the animal farming industry against disease threats.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11379843/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142152956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a whole-cell <i>E. coli</i> overexpressing the enzyme alpha-galactosidase is used to biodegrade sugarcane bagasse, presenting a sustainable approach for agricultural waste utilization. Alpha-galactosidase is an enzyme that breaks down alpha-D-galactose residues at the non-reducing ends of oligosaccharides (such as raffinose, stachyose, and verbascose), complex galactomannans, and galactolipids. Submerged and solid-state fermentation-mediated hydrolysis of bagasse waste using recombinant <i>E. coli</i> overexpressing α-galactosidase shows a decrease in the level of α-galactosides releasing sucrose and reducing sugars, indicating a continuous breakdown of the cell wall. Scanning electron microscopy indicates substantial disintegration of cell wall fibers under both submerged (12 h) and solid-state (7 days) fermentation, confirming the disruption of bagasse cell wall structural integrity. The 2XM9 media was found competent for both total protein and enzyme activity; the total protein concentration was 2553 µg/ml after 28 h of induction with an enzyme activity of 0.445 gal units/µg of protein after 16 h of induction at 24 °C.

In this study, LCB degrading enzymes of endophytic and litter fungi were screened for their tolerance to potential pretreatment-derived inhibitors. Several fungi produced endo- and exoglucanases that remained functional in the presence of lignocellulose-derived phenolics. Some were also active in the presence of tannic acid. Additionally, thermostable endoglucanase activity was observed in some fungi. The ability of some of these fungi to utilize furaldehyde inhibitors as a sole carbon source was also noted. The culture supernatants of the fungal strains were tested in hydrolysis experiments using microcrystalline cellulose as a substrate, in the presence of lignocellulose phenolics and tannic acid.

The leaves of <i>A. salvifolium</i> collected and subjected for the standard procedure of Soxhlet extraction using distilled water as a solvent. With the help of an aqueous extract AgNPs were synthesized from silver nitrate using phyto-reduction method. Further, synthesized AgNPs were characterized using several analytical techniques such as UV, FTIR, SEM-EDX, XRD, particles size and zeta potential. Synthesized AgNPs were tested for antibacterial, antioxidant, anticancer for lung cancer cell line and flowcytometry-based pathway studies. The visual observation confirmed the formation of AgNPs from the aqueous extract by changing yellow to brown colour formation. Further, characterization techniques also confirmed the formation of AgNPs. Antibacterial activity results showed that the tested AgNPs were potent against bacterial pathogens with a higher zone of inhibition. Further, the antioxidant and anticancer activity of AgNPs revealed that the AgNPs have exhibited significant results with a good percentage of inhibition. Further, the flow cytometry studies confirmed that the AgNPs inducing apoptosis and cell cycle arrest in lung cancer. The phytochemicals of <i>A. salvifolium</i> plant have successfully synthesized AgNPs. In the case of performed biological activity, the synthesized silver nanoparticles exhibited potent activity. In future these AgNPs can be taken for molecular and in vivo studies to identify their efficacy using in vivo and molecular models.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11415561/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142278669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
