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 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 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 کاملIn Vitro Alterations in Ruminal Parameters by Megasphaera Elsdenii Inoculation on Subacute Ruminal Acidosis (sara)
SARA is a common and serious problem in well-managed and intensive dairy herds or beef cattle operations, because of triggering other metabolic disorders and causing lactation-fertility losses. It is a metabolic disease in dairy cattle that occurs during early and mid-lactation and has traditionally been characterized by low rumen pH, but lactic acid does not accumulate as in acute lactic acid ...
متن کاملIn vivo Alterations in Ruminal Parameters by Megasphaera elsdenii Inoculation on Subacute Ruminal Acidosis (SARA)
SARA is a common and serious metabolic disorder in early lactation in dairy cattle and in finishing beef cattle, caused by diets with high inclusion of cereal grain. This experiment was performed to determine the efficacy of Megasphaera elsdenii, a major lactate-utilizing bacterium in prevention/treatment of SARA in vivo. In vivo experimentation, it was used eight ruminally cannulated rams and ...
