BIAs are currently exclusively produced through crop farming which adversely affects the supply chain resilience of BIA-based medication because availability is limited by low accumulation in plants and harvest seasons. Also, yields fluctuate due to annual weather changes and decrease overall due to global climate change impact on agriculture. Here we review the potential of chemical synthesis, synthetic microbial pathways and genetically engineered plants (cell- and tissue culture) as alternative BIA production approaches. The challenges and opportunities to achieve economically viable BIA titers in the gram per liter range are highlighted. Chemical BIA synthesis is robust and predictable, but yields are often <30% due to the complex chemical structures and the necessary asymmetric synthesis. Synthetic microbial pathways can be engineered into heterologous production hosts like <em>Escherichia coli</em> and <em>Saccharomyces cerevisiae</em>. Whereas the former produces amino acid precursors at high titers, it fails to provide active cytochrome P450 enzymes necessary for BIA synthesis. Yeasts enable the expression of full biosynthetic pathways but struggle with relevant product titers (often <10 mg L<sup>-1</sup>). Alternatively, genetic engineering can activate the endogenous BIA pathway for a given alkaloid in the native host plant or cell cultures thereof, but currently lacks selectivity of activation and scalability of the processes. Overcoming current barriers to competitiveness will require future research to build upon the works summarized in this review.</div></div>","PeriodicalId":8946,"journal":{"name":"Biotechnology advances","volume":"85 ","pages":"Article 108700"},"PeriodicalIF":12.5,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its potential, syngas fermentation is based predominantly on pure cultures, which faces significant challenges, including the limited portfolio of generated compounds (primarily acetate and ethanol) and their low productivity. To address these bottlenecks, the potential of microbial consortia as effective platforms for syngas conversion has been evaluated. Syngas biomethanation using mixed cultures is a well-established process, with pilot-scale implementations yielding promising results. Alternatively, the production of carboxylic acids has emerged as an interesting option compared to pure cultures, as comparable acetate productivities can be achieved along with the possibility for chain elongation to butyrate or caproate. However, the feasibility of using mixed cultures to produce alcohols and other high-value compounds from syngas remains underexplored. Advancing the field will also require the development of innovative technologies to overcome inherent barriers and fully unlock the potential of syngas-based bioprocesses. Key challenges include the presence of impurities and variability in syngas composition, mass transfer limitations in bioreactors, and the need for efficient downstream effluent purification. In this context, mixed cultures emerge as a robust approach capable of buffering syngas fluctuations and tolerating certain impurities.

Within the bioeconomy, plants serve as a renewable, sustainable, and cost-effective source of foods, fuels, chemicals, and materials. However, traditional breeding and single-gene engineering approaches fall short in addressing complex traits (e.g., drought tolerance, disease resistance, yield, nutrient use efficiency) which are controlled by multiple genes. The complexity of plant biology often necessitates the use of multigene engineering (MGE), which involves simultaneous ectopic expression, up/down-regulation, or editing of multiple genes, to enhance plant traits relevant to the bioeconomy. These genes may be associated with distinct traits or function as components of specific metabolic and regulatory pathways. This review summarizes current technologies for MGE within the synthetic biology-driven Design-Build-Test-Learn (DBTL) framework, detailing its four key stages: Design – gene construct development; Build – DNA assembly and plant transformation; Test – the molecular, biochemical, and physiological characterization of engineered plants; and Learn – computational modeling to refine, multiplex and iterate the process. Despite good progress in the applications of MGE in biofortification, metabolic engineering, and stress resilience, challenges remain in construct stability, coordinated gene expression, and regulatory predictability.
