ENDOGENOUS RESPIRATION OF STAPHYLOCOCCUS AUREUS

Abstract

The endogenous respiration of Staphylococcus aureus is dependent upon the medium used to 507

Comparative Metabolism of Virulent and Avirulent Staphylococci*

“…Glutamic acid, therefore, functions as only one of the pool amino acids supplying substrate for endogenous respiration of coagulasepositive cells. These results are consistent with those reported by Ramsey (1962). When 11 fresh clinical isolates of coagulase-positive staphylococci were analyzed for their Oz/NH3 ratios during endogenous diminution, the values ranged from 2.0 to 5.5.…”

Some Aspects of the Endogenous Metabolism of Bacteria

“…The utilization of free amino acid pools as endogenous substrates has since been shown to occur in Nocardia rugosa (2) and Staphylococcus aureus (64). During starvation of washed mycelial suspensions of N. rugosa, both the endogenous Qo, and Qo, (glucose) fall by approximately the same value.…”

Production of α-toxin by starved staphylococci

“…Starvation caused reduction of the free amino acid pool (63%) protein (36%) and RNA (36%) ( Table 1). This degree of endogenous turnover is typical for S. aureus [2,5,15]. The number of viable cells remained at the same level throughout the 3 h period.…”
