Introduction

Formaldehyde is a kind of xxx. As the rapid economic development in China, the residential conditions of people have been greatly improved. Unfortunately, the potential harm of their indoor decoration was always neglected until people get sick. One of the most harmful gases of the indoor pollution could be the formaldehyde. Formaldehyde is a kind of toxic gas with strong stinky smell. It could cause allotrionmia, abnormal lung function, dysimmunity and genetic damages. To decrease the concentration of HCHO, we got Air Exchanges, Physical adsorption, negative air ions, Photocatalyst pathway and etc. We thought that the Biological methods is the best. It’s fast, it’s simple, and it’s safe. Therefore, we decided to cultivate a plant which got the ability to metabolize the formaldehyde. Actually, all kinds plants can degrade the formaldehyde, but we decide to make their formaldehyde degradation system works better. There are two pathways to degrade the formaldehyde in plants. One is the Assimilation pathway, another is Oxidative pathway.
