1. Remoção de nitrogênio em biofiltros aerado e anóxico, com alto índice de vazios e sem remoção de lodo
A disposição inadequada do nitrogênio em corpos receptores gera problemas como: toxicidade para seres vivos; consumo de oxigênio do meio para atender a demanda nitrogenada; eutrofização; e contaminação dos aquíferos por nitrato. Por esta razão é muitas vezes necessário que seja realizado tratamento complementar dos esgotos para eliminar, ou reduz

2. Respirometry kinetics of phenol oxidation by Comamonas testosteroni Pb50 under various conditions of nutritional stress
Kinetics of phenol biodegradation using suspended biomass of Comamonas testosteroni Pb50 (monoculture) was measured under conditions of nutrient abundance, limitation, and prolonged cell starvation in a fed-batch reactor, with phenol being the sole carbon and energy source. The pre-washed cells were applied for measurement of the phenol and oxygen uptake rat

3. Avaliação da aplicação de acido folico em tratamento aerobio de aguas residuarias. / Evaluation of application of folic acid in aerobic wastewater treatment .
They are deficiency of vitamins in sludge of biological wastewater treatment, especially the folic acid, that acts as micronutrient for certain bacteria and stimulating its growth. This work evaluated the effect of different concentrations of folic acid on the sludge in normal physiologic conditions and in endogenous respiration. The system was carried out b

4. Influence of Glutamic Acid on the Endogenous Respiration of Bacillus subtilis
Clifton, C. E. (Stanford University, Stanford, Calif.), and John Cherry. Influence of glutamic acid on the endogenous respiration of Bacillus subtilis. J. Bacteriol. 91:546–550. 1966.—Amino acids serve as the major initial endogenous substrate for Bacillus subtilis. The endogenous activity of freshly harvested washed cells is high and falls off rapidly w

5. Activation of Endogenous Respiration and Anion Transport in Corn Mitochondria by Acidification of the Medium 1
Acidification of the suspending medium of corn mitochondria (Zea mays L., WF9 × Mo17) from pH 7.5 to pH 6.8 to 6.4 initiates osmotic swelling with the transportable anions citrate, sulfate, and phosphate. Swelling becomes pronounced with a combination of citrate plus sulfate or phosphate. Acidification proves to activate endogenous respiration, which is ess

6. ENDOGENOUS RESPIRATION OF STAPHYLOCOCCUS AUREUS
Ramsey, H. H. (Stanford University, Palo Alto, Calif.). Endogenous respiration of Staphylococcus aureus. J. Bacteriol. 83:507–514. 1962.—The endogenous respiration of Staphylococcus aureus is dependent upon the medium used to grow the cell suspension. Within wide ranges, the concentration of glucose in the medium has no effect upon subsequent endogenous

7. Respiration and viability of thermally injured Saccharomyces cerevisiae.
Resting cells of Saccharomyces cerevisiae Y25 were heated at 56 degrees C for 0 to 2 min. Respiratory activity of the cells reflected the severity of the heat stress. The endogenous respiration was approximately 50 microliter of O2/mg per h for cells heated for 2 min at 56 degrees C as compared with 2 microliter of O2/mg per h for nonheated cells. There was

8. ENDOGENOUS RESPIRATION OF BACILLUS CEREUS
Clifton, C. E. (Stanford University, Stanford, Calif.), and J. M. Sobek. Endogenous respiration of Bacillus cereus. J. Bacteriol. 82:252–256. 1961.—The endogenous respiration of washed cells of Bacillus cereus varies with the nature of the growth medium and with time. The respiratory quotient of cells harvested from nutrient agar remained quite constant

9. Endogenous Dark Respiration of the Blue-Green Alga, Plectonema boryanum
Endogenous dark respiration in the blue-green alga Plectonema boryanum is markedly affected by preincubation in the light: it can be increased from a basal rate of 5 nmoles of O2 to 55 nmoles of O2 per mg of cell protein per min after exposure of the cells to light for 8 to 10 hr. Under conditions of enhanced dark respiration, cyanophage multiplication in th

10. Respiration of Bdellovibrio bacteriovorus Strain 109J and Its Energy Substrates for Intraperiplasmic Growth
Measurements of oxidation rates, respiratory quotients (RQ), and release of 14CO2 from uniformly labeled substrates showed that glutamate, α-ketoglutarate, and synthetic and natural amino acid mixtures are oxidized by suspensions of Bdellovibrio bacteriovorus strain 109J. The oxidation of these substrates largely suppress the endogenous respiration of the B

12. NITROGENOUS SUBSTRATES OF ENDOGENOUS RESPIRATION IN PSEUDOMONAS AERUGINOSA
Gronlund, Audrey F. (University of British Columbia, Vancouver, Canada) and J. J. R. Campbell. Nitrogenous substrates of endogenous respiration in Pseudomonas aeruginosa. J. Bacteriol. 86:58–66. 1963.—The nature of the nitrogenous reserves of Pseudomonas aeruginosa that are oxidized during endogenous respiration was studied by following the changes in th
