Re: DIG-L: IC50 for methanogens

["Jerome Gay" <jerome.gay@oser.net>]

Dear all,

 

I have some figures about it. It comes from "short course on design municipal wastewater treatment plants" of Prof. Dr Surapol Saipanich from the Chulalongkorn University in Bangkok. I did not verify this figures and I do not know if it is for methanogen or acetogen microorganisms.

 

Toxic and inhibitory concentrations of selected organic materials in anaerobic digestion :

Compound	Concentration resulting in  50% activity mM
1-Chloropropène	0,1
Nitrobenzène	0,1
Acroléine	0,2
1-Chloropropane	1,9
Formaldéhyde	2,4
Acide Laurique	2,6
Éthyle Benzène	3,2
Acrylonitrile	4
3 Chloro-1,2-Propanediol	6
Croton aldéhyde	6,5
Acide 2-Chloropropionique	8
Vinyle Acétate	8
Acétaldéhyde	10
Éthyle Acétate	11
Acide Acrylique	12
Catéchol	24
Phénol	26
Aniline	26
Résorcinol	29
Propanol	90

Sincerely yours.

Subject: DIG-L: IC50 for methanogens

Dear Friends,

I need to know IC50(50% Inhibition Concentration) values of the following chemicals for the Methanogenic Bacteria.

 

1. Acetone

2.Iso Propyl Alcohol

3.Methyl Acetate

4.Hexane

5.Dimethyl Sulfoxide

6. Dimethyl formamide

 

Does anybody know any University/Research Institue/ Industrial Labs conducting such studies.

 

I would appreciate receiving a feedback .

 

Best Regards,
