Phytotechnology and Photosynthesis Từ một quan điểm thực tế, phytotechnology là việc sử dụng các nhà máy trong các ứng dụng công nghệ sinh học môi trường, và dựa trên nhiều đặc điểm đã được mô tả. Về mặt này, nó không đại diện cho một công nghệ duy nhất, thống nhất, hoặc thậm chí ứng dụng, nhưng thay vì là một chủ đề rộng lớn hơn, xác định hoàn toàn bởi các sinh vật phản ứng được sử dụng. Như vậy phạm vi cơ bản của chương này là rộng lớn hơn và việc sử dụng và cơ chế. | 7 Phytotechnology and Photosynthesis From a practical standpoint phytotechnology is the use of plants in environmental biotechnology applications and draws on many of the characteristics which have already been described. In this respect it does not represent a single unified technology or even application but rather is a wider topic defined solely by the effector organisms used. Thus the fundamental scope of this chapter is broader and the uses and mechanisms described somewhat more varied than for many of the preceding biotechnologies discussed. Plants of one kind or another can be instrumental in the biological treatment of a large number of substances which present many different types of environmental challenges. Accordingly they may be used to remediate industrial pollution treat effluents and wastewaters or solve problems of poor drainage or noise nuisance. The processes of bioaccumulation phytoextraction phytostabilisation and rhizofiltration are collectively often referred to as phytoremediation. Although it is sometimes useful to consider them separately in most functional respects they are all aspects of the same fundamental plant processes and hence there is much merit in viewing them as parts of a cohesive whole rather than as distinctly different technologies. It is important to be aware of this particularly when reading a variety of other published accounts as the inevitable similarities between descriptions can sometimes lead to confusion. Moreover the role of phytotechnology is not limited solely to phytoremediation and this discussion as explained above is more deliberately inclusive of wider plant-based activities and uses. Despite the broad spectrum of potential action exhibited by plants in this respect there are really only three basic mechanisms by which they achieve the purpose desired. In essence all phytotechnology centres on the removal and accumulation of unwanted substances within the plant tissues themselves their removal and .
