The present study examined the biodegradation rate of benzene vapors in a two phase stirred tank bioreactor by a bacterial consortium obtained from wastewater of an oil industry refinery house. Initially, the ability of the microbial consortium for degrading benzene was evaluated before running the bioreactor. The gaseous samples from inlet and outlet of bioreactor were directly injected into a...
Citric acid production is generally carried out in an aqueous medium stirred tank reactors (STR), where the solubility of oxygen low and demand microbial cultures high. Thus, for this bioprocess, providing adequate mass transfer rate (OTR) from gas phase into culture main challenge bioreactor selection operation. In study, citric by Yarrowia lipolytica W29 crude glycerol, batch cultures, was pe...
Introduction: In real Conditions, pollution emission are mostly released as mixed components rather than a single pure emission of the chemicals. In this study, a miniature stirred tank bioreactor was optimized for treatment of waste gas containing BTX (benzene, toluene and xylene). . Material and Method: The sludge of an oil refinery was sampled based on the assumption that it contains BTX-d...
The objective of this work was to produce an herbicide by submerged fermentation in a stirred-tank bioreactor and to assess the potential herbicidal in pre-emergence, post-emergence, and in a detached leaves of Cucumis sativus var species. wisconsin (cucumber) and Sorghum bicolor (sorghum) species. Fermentations were carried out in a stirred-tank bioreactor with useful volume of 3L. Stirring ra...
