3Power output, and with its power outputs lower (Li Lianhua, 2009) of complex compound such as beer waste water etc.And the pilot experiment that Rabaey (2008) etc. carry out is that to have studied volume be 1m to fuel with the beer waste water
3The ruuning situation of microbiological fuel cell; Exist problems such as corrosion and electrogenesis efficient are low during the course; And point out that in second domestic microbiological fuel cell meeting there is bigger problem in microbiological fuel cell as the method for waste water control, but can be used for producing hydrogen.
Plant carries out photosynthesis, fixation of C O through chlorophyll
2Synthetic carbohydrate.According to kind and the environmental condition of plant, nearly 60% the C that is fixed can be input to root.Research shows. 30%～40% root of soil organism sum from root secretion and death.Mainly contain: (1) carbohydrate, organic acid etc.; (2) polymeric carbohydrate and enzyme etc.; (3) cellular material of death; (4) gaseous matter such as ethene.Gransee (2001) etc. utilizes quartz sand to cultivate its water-soluble root secretion composition of corn research; Find that hydrocarbon accounts for 64%, amino acid and amino salt account for 22%, organic acid is 14%. in independent compound analysis, to learn; Hydrocarbon mainly is glucose, fructose and sucrose; Citric acid and butanedioic acid account for organic acid 80%; Mainly contain glutamic acid, aspartic acid and serine .Paynel discoveries such as (2001) in the amino acid, in clover and rye grass amino acid, find in the maximum .Aulakh research rice root secretion such as (2001) of serine and amion acetic acid ratio; Malic acid concentration is the highest in organic acid, secondly is tartaric acid, butanedioic acid citric acid and lactic acid.
