Glucose fermentation by Leuconostoc me8enteroides has been shown to proceed via a mechanism which differs from the classical Embden-Meyerhof glycolytic scheme. DeMoss, Bard, and Gunsalus (1951) found no evidence in cell-free extracts of this organism for the key enzyme aldolae but showed that cellular suspensions ferment glucose to equimolar quantities of ethanol, C02, and lactate as obligatory...

Thc sterilizing effect of supercritical carben dioxide (SC-CO,) is described as compared with gaseous C02(G-CO,) and liquid CO,(L-CO,). Baker's yeast, ltscherichia eoli, Staphylococcus aure us and eonidia'ofAspergiilus niger were sterilized by treating with SC-CO, at 200 atm and 350C when the water contcnt of each microorganism was 70 .90%, However, dry cells with a water content of 2 .1O% coul...

effects of acute systemic hypoxia on the cardiovascular system (cys) and respiration of spontaneously breathing cats were studied in two conditions. 1): hypoxic air (6-8% 02 in n2) was given to the animal to induce systemic hypoxia for 20 minutes. hyperventilation at this condition lowered arterial c02 tension (pac02 hypocapnia). 2): in the second run, induction of hypocapnia was prevented by a...

Objectives: After validation of impedance cardiography (ICG) in healthy children, this same device was tested in children with cystic fibrosis (CF) to validate its capability of measuring cardiac output (Q) in this population. Design: Comparative study of ICG vs the indirect Fick (C02) method. Setting: Tertiary care children's teaching hospital. Patients: Twenty-one CF children with mean FEVX o...

ty, lactic acid bacterial count, and sensery properties. Kimchi sainples treated with pressurized C02 had relatiyely a higher pH value, lower titratable acidity, and smaller lactic acid bacterial population than the untreated sample. A sensory eyaluation showed that the soumess alld overall acceptability of trettted kimchi were better than those ef the contro]. The color, flayor and texture wer...
