Anaerobic microbial LCFA degradation in bioreactors.
This paper reviews recent results obtained on long-chain fatty acids (LCFA) anaerobic degradation. Two LCFA were used as model substrates: oleate, a mono-unsaturated LCFA, and palmitate, a saturated LCFA, both abundant in LCFA-rich wastewaters. 16S rRNA gene analysis of sludge samples submitted to continuous oleate- and palmitate-feeding followed by batch degradation of the accumulated LCFA dem...
متن کاملDegradation in an Anaerobic Microbial Ecosystem
Anaerobic digestion of biomacromolecules in various microbial ecosystems is influenced by the variations in types, qualities, and quantities of chemical components. Nuclear magnetic resonance (NMR) spectroscopy is a powerful tool for characterizing the degradation of solids to gases in anaerobic digestion processes. Here we describe a characterization strategy using NMR spectroscopy for targeti...
متن کاملMicrobial aspects of anaerobic BTEX degradation.
Combined with conventional methods, developments in both geochemical (delineation of redox processes) and molecular microbial methods (analysis of 16S rDNA genes and functional genes) have allowed us to study in details microorganisms and genes involved in the anaerobic degradation of benzene, toluene, ethylbenzene and xylene (BTEX) under specific redox conditions. This review summarizes recent...
متن کاملAtrazine degradation in anaerobic environment by a mixed microbial consortium.
Atrazine degradation by anaerobic mixed culture microorganism in co-metabolic process and in absence of external carbon and nitrogen source was studied at influent atrazine concentration range of 0.5-15 mg/l. Wastewater of desired characteristic was prepared by the addition of various constituents in distilled water spiked with atrazine. In co-metabolic process, dextrose of various concentratio...
متن کاملLearning to Operate Anaerobic Bioreactors
This chapter describes the main parameters and the different techniques used to characterize an anaerobic bioreactor and how to apply the obtained information to learn how to operate it. In this kind of biological systems, the large number of processes, operating parameters and removed compounds involved makes necessary to combine knowledge from both Microbiology and Chemical Reactor Engineerin...
