SummarySegmented, filamentous bacteria (SFBs) are autochthonous, apathogenic bacteria, occuring in the ileum of mice and rats. Although the application of formal taxonomic criteria is imposible due to the lack of an in vitro technique to culture SFBs, microbes with a similar morphology, found in...
SummaryThe information currently available on the breakdown of spermidine and putrescine by microorganisms is reviewed. Two major metabolic routes have been described, one for the free bases via δ1-pyrroline (4-aminobutyraldehyde), the other via N-acetyl derivatives. In both pathways oxidases or...
SummaryOver the last 20 years or so, the obligate methane-oxidizing bacteria (methanotrophs) have attracted considerable interest. As they grow on a relatively cheap and abundant carbon source, they appeared ideal organisms for the production of bulk chemicals, single-cell protein and for use in...
SummaryIn amino acid fermenting anaerobic bacteria a set of unusual dehydratases is found which use 2-hydroxyacyl-CoA, 4-hydroxybutyryl-CoA or 5-hydroxyvaleryl-CoA as substrates. The extremely oxygen-sensitive 2-hydroxyacyl-CoA dehydratases catalysing the elimination of water from (R)-lactyl-CoA...
SummaryThe application of genetically modified microorganisms (GEMMOs) in agriculture has great possibilities. However, the lack of knowledge on the occurrence of unwanted effects on the soil ecosystem still prevents the large-scale use of GEMMOs. Moreover, experimental work in risk assessment...
SummaryAcetate is the precursor of approximately two-thirds of the methane produced in anaerobic bioreactors. Only two genera of methanogenic archae are known to use acetate as sole energy source: Methanosarcina and Methanothrix. Methanosarcina appears to be a generalist with a high growth rate,...
SummaryIn this paper, it is suggested that specificity and non-specificity in (oral) microbial adhesion are different expressions for the same phenomena. It is argued that the same basic, physico-chemical forces are responsible for so-called ‘non-specific’ and ‘specific’ binding and that from a...
