Conventional agricultural practices often rely on synthetic fertilizers and pesticides which have immense and adverse effects on humans, animals and environments. To minimize these effects, scientists world over are now deeply engaged in finding alternative approached for crop production which are less dependent on chemical inputs. One such approach is the use of rhizospheric bacteria as vital components of soil fertility and plant growth promotion (PGP) through their direct and indirect processes in plant rhizospheres. Among the most studied rhizobacteria are the Bacilli, particularly for production of antibiotics, enzymes and siderophores all of which are important aspects of PGP. Despite this, little information is available especially on their potentiality in crop production and their direct application only involves a few species, leaving a majority of these important rhizobacteria unexploited. This paper gives an overview of the unique properties of Bacilli rhizobacteria as well as their different PGP mechanisms that if mined can lead to their successful application and agricultural sustainability. It further points out the missing aspects with regards to these important rhizobacteria that should be considered for future research. This information will be useful in analyzing the PGP abilities of Bacilli rhizobacteria with an aim of fully mining their potential for crop production and environmental sustainability.

芽孢杆菌根瘤菌对可持续作物生产和环境可持续性的潜力

传统的农业实践通常依靠合成肥料和杀虫剂,这些合成肥料和杀虫剂会对人类,动物和环境产生巨大的不利影响。为了最大程度地减少这些影响,世界各地的科学家现在都在致力于寻找替代作物的替代方法,这些替代方法对化学投入的依赖性较小。一种这样的方法是通过根际细菌在植物根际中的直接和间接过程,将其用作土壤肥力和促进植物生长(PGP)的重要组成部分。在研究最多的根际细菌中,有芽孢杆菌,特别是用于生产抗生素,酶和铁载体的细菌,所有这些都是PGP的重要方面。尽管如此,很少获得信息,特别是关于其在作物生产中的潜力,其直接应用仅涉及少数几个物种,这些重要的根际细菌大部分未被利用。本文概述了芽孢杆菌根瘤菌的独特性质,以及它们的不同PGP机制,如果将其开采,可成功应用它们并实现农业可持续发展。它进一步指出了与这些重要的根际细菌有关的缺失方面,应在以后的研究中加以考虑。该信息将有助于分析根际芽孢杆菌的PGP能力,以充分挖掘其在作物生产和环境可持续性方面的潜力。它进一步指出了与这些重要的根际细菌有关的缺失方面,应在以后的研究中加以考虑。该信息将有助于分析根际芽孢杆菌的PGP能力,从而充分挖掘其在作物生产和环境可持续性方面的潜力。它进一步指出了与这些重要的根际细菌有关的缺失方面,应在以后的研究中加以考虑。该信息将有助于分析根际芽孢杆菌的PGP能力,以充分挖掘其在作物生产和环境可持续性方面的潜力。
