The Advance of the Enhancement of Plant Heavy Metal Resistance by Plant Growth-promote Bacteria

Abstract:

Recently, phytoremediation is considered to be a promising alternative for extraction of heavy metals from polluted soils. Many plant species are useful resources but not tolerant to heavy metals, making it difficult in practical application. Plant growth-promote bacteria are environmental friendly and highly diversity, which will probably facilitate the practical realization of phytoremediation. With the development in technology and resources, bio-regulation will make phytoremediation more viable and more valuable. This paper reviews the emerging bio-regulation technology in recent years, mainly in screening, identification and application of plant growth-promote bacteria.
