Characteristics of Plants Used for Phytoremediation of Heavy Metals

Plants suitable for phytoremediation should possess a series of characteristics (1) ability to accumulate metals preferably in the aboveground parts, (2) tolerance to metal concentration accumulated, (3) fast growth and high biomass, (4) widespread highly branched root system, (5) easy harvestability, and (6) non consumable by humans and animals (Arthur et al., 2005). However, plant species just can partially fulfill these conditions. For example, those few plants that can accumulate metals to...

Metabolism of Hazardous Phenolic Compounds in Plants

Phyto Degradation

Phenolic Compounds Metabolism and the Green Liver Model It has generally been accepted that several enzyme systems, not necessarily physiologically connected, form a metabolic cascade for the detoxification, breakdown and final storage of organic xenobiotics Schr der et al., 2008 . Detoxification mechanisms described for phenolic compounds, resemble more the reactions in the animal liver than the bacterial metabolism, following the green liver model proposed for the metabolism of other...

The Use of Hydroponics and Plant Tissue Culture Technologies for Dye Degradation

The cultivation of plants and their further experiments with dye degradation can be carried out using hydroponic solutions. These solutions provide a nutrient status which is close to that of the soil in which the plant usually grows. Thus, such solutions are enriched with various macro and micro nutrients and can be used for the cultivation and or maintenance of plants for phytoremediation. The use of hydroponics provides a cost effective method for phytoremediation of dyes. Aubert and...
