Polarographic measurement of dissolved oxygen in yeast fermentations.
M1illions of cubic feet of air are sparged daily into a commercial baker's yeast fermentation to fulfill the oxygen demands of the organism. The costs for air compression are sizeable and, in some cases, the capacity of the air supply system may impose restrictions on the number or types of fermentations which can be scheduled. The rate of air supply required for each type of yeast fermentation...
متن کاملThe Effect of Pollutants Dissolved Oxygen and Temperature Change (Case Study:Ghezel-Ozen River)
Rivers can absorb certain amounts of contamination relying on different factors such as: river discharge, the primary conditions of the river, the river depth, discharge and the river viscosity of the offloaded wastes in the river. From parameters of water quality point of view, it is recom-mended to determine some parts of the river which are lower than the standard level in order to find out ...
متن کاملDynamic measurement of the volumetric oxygen transfer coefficient in fermentation systems.
Introduction Much has been written and said about the scale-up of fermentation systemsS). In general, it has been agreed that the best scale・,-up method is to maintain a constant voiumetric oxygen mass transfer coeMcient. The problem with this procedure has been the differing methods by which the transfer coeMelent has been obtained. Various investigators have used the su}fite oxidation2), pola...
متن کاملPolarographic Oxygen Electrode
A method has been developed for the continuous monitoring of oxygen tension in solutions and gases. The oxygen is reduced at a platinum surface which is covered with a plastic membrane. The silver-silver oxide reference electrode is also included under the membrane. Drift is less than 10 per cent for a period of days, and temperature compcnsation is possible. A number of uses to which it has be...
متن کاملpolarographic method versus analytical method in determination of dissolved oxygen and n-no3
polarographic method is considered as an alternative laboratory technique for analytical method in determination of dissolved oxygen and n-n03. analytical method is a time consuming technique and is subject to several interferences due to some of constituents in sewage. in this laboratory research, the polar graphic technique with, mercury drop electrodes and titrometric method were applied in ...
