集约化耕作做法增加了化学农药和化肥的消费,从而给人类和动物带来健康问题,并导致自然生态系统的恶化。生物材料合成的推广有可能导致合成产品的替代,提高土壤肥力,保护植物免受病原体攻击,并提高农业部门的生产力,从而减少环境污染。涉及使用和改进使用多糖的包封的微生物生物工程具有解决环境问题和促进绿色化学所需的潜力。本文描述了各种封装技术和多糖,它们具有巨大的应用能力来封装微生物细胞。该综述阐明了可能导致封装期间活细胞计数减少的因素,特别是使用喷雾干燥法,如果需要高温来干燥悬浮液,这可能会损害微生物细胞。应用多糖作为有益微生物载体的环境优势,由于其完全的生物降解性,不会对土壤构成风险,也显示了。封装的微生物细胞可以帮助解决某些环境问题,例如改善植物害虫和病原体的不利影响。促进农业可持续性。
Intensive farming practices have increased the consumption of chemical-based pesticides and fertilizers thereby creating health issues for humans and animals and also causing a deterioration in the natural ecosystem. The promotion of biomaterials synthesis could potentially lead to the replacement of synthetic products and improve soil fertility, protect plants from pathogen attacks, and enhance the productivity of the agricultural sector resulting in less environmental pollution. Microbial bioengineering involving the use and improvement of encapsulation using polysaccharides has the required potential to address environmental issues and promote green chemistry. This article describes various encapsulation techniques and polysaccharides which have an immense applicable capability to encapsulate microbial cells. The review elucidates the factors that may result in a reduced viable cell count during encapsulation, particularly using the spray drying method, where a high temperature is required to dry the suspension, this may damage the microbial cells. The environmental advantage of the application of polysaccharides as carriers of beneficial microorganisms, which do not pose a risk for soil due to their full biodegradability, was also shown. The encapsulated microbial cells may assist in addressing certain environmental problems such as ameliorating the unfavourable effects of plant pests and pathogens, and promoting agricultural sustainability.
