Abstract

Nowadays in worldwide agriculture, sustainable strategies are implemented to reduce negative effects on ecosystems created by conventional practice, mainly environmental pollution caused by intensive use of fertilizers and chemical plant protection products. Bacteria from the genus Pseudomonas can be considered biocontrol and plant growth-promoting agents due to their various plant beneficial traits e.g., siderophores production, phytohormones synthesis, antagonism against phytopathogenic fungi. This is a reason for increasing researchers' interest in improving of existing or elaborating new technologies that enable the effective application of these bacteria in agriculture. Pseudomonads are non-sporulating bacteria and it is a major constraint for creating bioformulation for commercial use with a sufficiently high stable number of viable cells during shelf-life. Therefore, scientists are making efforts to improve techniques of bioformulations to enable large-scale production and use of pseudomonads under field conditions. The aim of this review is to describe traits of Pseudomonas spp. which are useful in plant protection and growth-promotion and to highlight examined techniques for preparing bioformulations containing pseudomonads with sufficiently long shelf life.

假单胞菌在生物植物保护和促进生长中的应用
如今,在世界范围内的农业中,可持续战略的实施是为了减少传统做法对生态系统造成的负面影响,主要是由于化肥和化学植保产品的大量使用造成的环境污染。假单胞菌属细菌具有多种植物有益特性,如产生铁载体、合成植物激素、拮抗植物病原真菌等,可被认为是生物防治和植物生长促进剂。这就是为什么越来越多的研究人员有兴趣改进现有的或精心设计的新技术,使这些细菌在农业中有效应用。假单胞菌是一种不产孢子的细菌,它是制造用于商业用途的生物制剂的一个主要限制,在保质期内具有足够高的稳定数量的活细胞。因此,科学家们正在努力改进生物配方技术,以便在野外条件下大规模生产和使用假单胞菌。本文综述了假单胞菌在植物保护和促进生长方面的特性,并重点介绍了制备具有足够长保质期的假单胞菌生物制剂的技术。
