This work focused on determining the effect of dissolved oxygen concentration (DO) on growth and metabolism of BHK-21 cell line (host cell for recombinant proteins manufacturing and viral vaccines) cultured in two stirred tank bioreactors with different aeration-homogenization systems, as well as pH control mode. BHK-21 cell line adapted to single-cell suspension was cultured in Celligen withou...
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...
This study was conducted to investigate the occurrence of PAH degrading microorganisms in two river systems in the Western Cape, South Africa and their ability to degrade two PAH compounds: acenaphthene and fluorene. A total of 19 bacterial isolates were obtained from the Diep and Plankenburg rivers among which four were identified as acenaphthene and fluorene degrading isolates. In simulated b...
In the present work, the effects of dual impeller configurations comprising of Rushton turbine (RT) and Concave-bladed disk turbine (CD-6) on the oxygen transfer profile and fermentation performance of kojic acid production by Aspergillus flavus Link 44-1 was investigated. Batch cultivations of A. flavus Link 44-1 were performed in 2 L stirred tank bioreactor. The fermentations were conducted u...
The present work deals with the kinetics of rifamycins production and degradation by Amycolatopsis mediterranei in submerged culture using industrial medium. Cultivations were conducted in shake flasks and stirred tank bioreactor to evaluate the influence of transfer of process to higher scale on overall process kinetics and to obtain better understanding for the kinetics of rifamycins producti...
In this study, a miniature stirred tank bioreactor was designed for treatment of waste gas containing benzene, toluene and xylene. Oxygen mass transfer characteristics for various twin and single-impeller systems were investigated for 6 configurations in a vessel with 10 cm of inner diameter and working volume of 1.77L. Three types of impellers, namely, Rushton turbine, Pitched 4blades and Pitc...
Background During the chronic myelogenous leukemia (CML) the Bcr-Abl oncoprotein is produced, which leads to unregulated cell proliferation. CML is treated with one of several targeting therapies such as imatinib, (formerly STI-571 [Glivec; Novartis, Switzerland]) a selective inhibitor that blocks tyrosin kinase activity of the Bcr-Abl oncoprotein. Apart from the second generation Bcr-Abl inhib...
