Abstract
As to the physiological or metabolic features of pathogenic staphylococci, there are only a few reports, compared with those of Escherichia coli which was treated in report I. In this report, the author reports about the physiological aspects, particularly about the terminal respiratory system of Staphylococcus albus, entering from the studies of glutamic acid metabolism: 1) Staph. albus has the so-called citric acid cycle as its terminal respiratory ststem. 2) As a result of oxidative deamination, glutamic acid enters into the citric acid cycle and is further oxidized through this cycle. Glutamic acid is, however, best oxidized of all the intermediates of citric acid cycle and the related compounds. 3) Glutamic-aspartic and glutamic-alanic transaminations are carried out by this organism, in which glutamic acid plays the central role. 4) Divalent metal ions (Mg(++), Mn(++) and Fe(++)) show no remarkable effect on the glutamate-respiration of Staph. albus. 5) Of the various inhibitors tested, sodium azide, 2: 4-dinitrophenol, sodium arsenite and 8-hydroxyquinoline inhibit the glutamate-respiration strongly, and the most remarkable is the inhibitive action of 8-hydroxyquinoline. 6) Of the various antibiotics used, the inhibitive action of aureomycin is the most remarkable. Penicillin also shows some inhibitive action at pH 5.4. 7) The inhibition of the glutamate-respiration of this organism by these various inhibitors and antibiotics shows usually the tendency to rise up in the region of lower pH.
