Journal ArticleDOI

Reductive dechlorination of 1,2-dichloroethane and chloroethane by cell suspensions of methanogenic bacteria

Christof Holliger, +3 more
- 01 Jan 1990 - 
TL;DR: Cell suspensions of methanogenic bacteria reductively dechlorinated 1,2-dichloroethane via two reaction-mechanisms and stimulated methanogenesis caused an increase in the amount of dechlorination products formed, whereas the opposite was found when methane formation was inhibited.
Journal ArticleDOI

Microbial reduction of manganese coupled to toluene oxidation

Alette A.M. Langenhoff, +6 more
- 01 Feb 1997 - 
TL;DR: Direct contact between the bacteria and the manganese oxide was found to be advantageous for a rapid toluene degradation, and could be further increased by adding organic ligands such as oxalic acid or nitrilotriacetic acid.
Journal ArticleDOI

Energetics of bacterial adhesion

M.C.M. van Loosdrecht, +1 more
- 01 Aug 1990 - 
TL;DR: In this article, two different physico-chemical approaches are described for the description of bacterial adhesion phenomena: surface Gibbs energy balance (SGE) and colloid chemical theories (DLVO theory).
Journal ArticleDOI

13C-NMR study of propionate degradation by a methanogenic coculture

Frans P. Houwen, +4 more
- 01 May 1987 - 
TL;DR: In vivo high-resolution 13C-NMR was used to study propionate oxidation in a methanogenic coculture and gives further evidence for the involvement of the methylmalonyl-CoA pathway.
Journal ArticleDOI

Determination of polyhydroxyalkanoates in activated sludge by ion chromatographic and enzymatic methods.

Rolf P.X. Hesselmann, +5 more
- 01 Mar 1999 - 
TL;DR: Two new detection methods for the determination of poly-beta-hydroxybutyrate (PHB) and -valerate (PHV) are described and are easier to perform than previous methods and are suitable for complex matrices such as activated sludge.
