Agitation-Aeration in Submerged Fermentation

Agitation-Aeration in Submerged Fermentation

For the successful operation of aerobic fermentations it is essential to supply the microorganiisms with sufficient oxygen to meet their requirements at any stage in the process. Failure to supply enough oxygen may lead to undesirable changes in enzymatic makeup (Rolinson, 1952) or death of the organisms (Hromatka et al., 1951), with a subsequent lower yield of the desired product. In general, ...

Aeration of Bacillus anthracis in submerged fermentation.

An investigationi was undertaken to determine the oxygen absorption rates of a submerged culture of Bacillus anthracis at all stages of its growth cycle. The determination of oxygen absorption rates of a pathogenic fermentation such as this by analysis of the exhaust gases seemed to present fewer technical difficulties than did those methods that depended upon polarographic determination of dis...

Optimization of Aeration and Agitation Rate for Lipid and Gamma Linolenic Acid Production by Cunninghamella bainieri 2A1 in Submerged Fermentation Using Response Surface Methodology

The locally isolated filamentous fungus Cunninghamella bainieri 2A1 was cultivated in a 5 L bioreactor to produce lipid and gamma-linolenic acid (GLA). The optimization was carried out using response surface methodology based on a central composite design. A statistical model, second-order polynomial model, was adjusted to the experimental data to evaluate the effect of key operating variables,...
