Microorganisms, such as fungi and bacteria, are crucial players in the production of enzymatic cocktails for biomass hydrolysis or the bioconversion of plant biomass into products with industrial relevance. The biotechnology industry can exploit lignocellulosic biomass for the production of high-value chemicals. The generation of biotechnological products from lignocellulosic feedstock presents several bottlenecks, including low efficiency of enzymatic hydrolysis, high cost of enzymes, and limitations on microbe metabolic performance. Genetic engineering offers a route for developing improved microbial strains for biotechnological applications in high-value product biosynthesis. Sugarcane bagasse, for example, is an agro-industrial waste that is abundantly produced in sugar and first-generation processing plants. Here, we review the potential conversion of its feedstock into relevant industrial products via microbial production and discuss the advances that have been made in improving strains for biotechnological applications.
微生物,如真菌和细菌,是生物酶制剂的关键参与者,这些酶制剂用于生物质水解或植物生物质向具有工业相关性的产品的生物转化。生物技术产业可以利用木质纤维素生物质生产高价值化学品。从木质纤维素原料生产生物技术产品存在几个瓶颈,包括酶解效率低、酶成本高以及微生物代谢性能受限。遗传工程为开发用于高价值产品生物合成的生物技术应用的改良微生物菌株提供了一条途径。例如,甘蔗渣是一种农业工业废物,在糖和第一代加工厂大量生产。在这里,我们综述了通过微生物生产将其原料转化为相关工业产品的潜力,并讨论了在提高用于生物技术应用的菌株方面所取得的进展。
