(v. t.) To sprinkle; to moisten by sprinkling; as, to sparge paper.
Example Sentences:
(1) Reaction of the enzyme with NO2- in the presence of NO increases the amount of N2O product significantly, while trapping the NO product as nitrosylhemoglobin or rapid removal of NO by sparging results in no detectable N2O production.
(2) Fumarate hydratase activity also decreased but alcohol dehydrogenase and the sum of the succinate dehydrogenase and fumarate reductase activities increased when residual O2 was removed from the sparging gas.
(3) Suspensions of Pseudomonas aeruginosa and Bacillus cereus were continuously sparged with nitrogen to remove gaseous products of nitrate reduction.
(4) The potential toxicity of these agents was examined in the absence of sparging (i.e., in spinner flasks) by using the attachment-independent Sf9 insect cell line as a model system.
(5) Furthermore, no physical cell damage caused by bubble sparging was observed.
(6) The use of a fluidized bed prevents biomass buildup, accommodates particulates in the feed stream, is compatible with gas sparging, and allows easy removal or addition of the active materials.
(7) The lag period was shortened in sparged cultures by decreasing both the pO(2) and the pCO(2), indicating that gas medium equilibration had not occurred in shaken cultures.
(8) The method involves growth linked introduction of glucose and ammonia to the culture, sparging with oxygen, and maintenance of aerobic conditions by gradually decreasing the temperature in the culture in order to keep the oxygen demand within the limits of the capacity of supply.
(9) The batch fermentation of suspended C. acetobutylicum NRRL-B-643 and its ability to produce solvents in the presence of membranes as the oxygen-elimination agent are described and compared with the conventional sparging technique used to maintain anaerobiosis.
(10) 1991, following paper in this issue) and the experimental and theoretical work of other researchers, several mechanisms of cell damage as a result of sparging are presented.
(11) The yields varied with sparging rates in agreement with a quantitative model of denitrification (Betlach, M. P., and Tiedje, J.M.
(12) Also a variety of sparging rates and sparger sizes and positions have been employed.
(13) Lungs were perfused for 3 min with oxygen equilibrated buffer, with or without 60 min prior warm anoxia, induced by initial perfusion with argon sparged buffer.
(14) The denitrifier Pseudomonas perfectomarina reduced nitrite under conditions of kinetic competition between cells and gas sparging for extracellular dissolved nitric and nitrous oxides, NOaq and N2Oaq, in a chemically defined marine medium.
(15) With cultures that were continuously sparged with nitrogen gas, glucose was fermented primarily to acetate and butyrate with a fixed stoichiometry.
(16) This was not observed for 2% CO2 immobilized bioreactor as well as shake flask control suspension cultures, which suggests that sparged C. roseus surface-immobilized cell cultures require 2% CO2 supplementation of the gas phase for both maximum growth and retained viability.
(17) Samples are mixed with water and sparged with nitrogen for 1 h with stirring in a water bath at 100 degrees C. The EDB collected on the adsorbent Tenax TA is eluted with hexane and determined by gas chromatography (GC) with electron capture detection (ECD) and confirmed with Hall electrolytic conductivity detection (HECD) using a second GC column.
(18) In addition, serum-free medium devoid of cells was partially degraded under continuous air sparging.
(19) The fit of the model to data at lower sparging rates, where normal denitrification products predominate, implies that the extracellular NOaq pool yield is independent of gas sparging rate.
(20) The proposed model is based on a similarity between heat transfer in gas-sparged pneumatic reactors and turbulent natural convection.
