Presence of lactate dehydrogenase and lactate racemase in Megasphaera elsdenii grown on glucose or lactate.
Activity of D-lactate dehydrogenase (D-LDH) was shown not only in cell extracts from Megasphaera elsdenii grown on DL-lactate, but also in cell extracts from glucose-grown cells, although glucose-grown cells contained approximately half as much D-LDH as DL-lactate-grown cells. This indicates that the D-LDH of M. elsdenii is a constitutive enzyme. However, lactate racemase (LR) activity was pres...
متن کاملButyryl-CoA dehydrogenase from Megasphaera elsdenii
The absorption coefficient of butyryl-CoA dehydrogenase from Megasphaera elsdenii at 450nm is determined as 14.4mM-1 cm-1 in the CoA-free form and 14.2mM-1 cm-1 in the CoA-liganded form (both yellow). The latter value is considerably higher than the earlier published estimate. Phenazine ethosulphate offers great advantages over phenazine methosulphate as a coupling dye in the catalytic assay de...
متن کاملEffects of an Aspergillus oryzae fermentation extract and other factors on lactate utilization by the ruminal bacterium Megasphaera elsdenii.
The objective of this study was to determine the effects of an Aspergillus oryzae fermentation extract (Amaferm) as well as other factors on lactate utilization by the ruminal bacterium Megasphaera elsdenii B159. Addition of Amaferm or a filter-sterilized Amaferm filtrate stimulated L-lactate uptake by both M. elsdenii and the ruminal selenomonad strain H18. Growth of M. elsdenii in medium that...
متن کاملMegasphaera elsdenii endocarditis.
A case of endocarditis caused by Megasphaera elsdenii is reported. This anaerobic grim-negative coccus has rarely been associated with human infections and has not previously been described as a cause of endocarditis.
متن کاملMetabolism and some characteristics of ruminal strains of Megasphaera elsdenii.
Megasphaera elsdenii belongs to the group comprising the ruminal and intestinal lactate- and sugar-fermenting species. In the present study the fermentation characteristics, metabolism of glucose and lactate, and susceptibility to antimicrobial agents of four ruminal strains were investigated. Particular attention was given to the mixed-substrate fermentation pattern and resultant fermentation ...
