The Gram-negative, facultative chemolithoautotrophic bacterium Ralstonia eutropha has
been intensively investigated for almost 50 years. Today it is the best studied 'Knallgas' …

The immobilization of whole cells involves the retention of catalytically active cells within a
restricted region of a bioreactor. Techniques which have been used to immobilize whole …

Oxygen transfer is one of the bottlenecks in conventional fermentation technology and it has
so far been almost totally overlooked with regards to high cell densities and immobilized …

Due to the significant oxygen requirement during citric acid production and the relatively low
solubility of oxygen in water, aeration is critical. The potential use of n-dodecane as an …

The mission of the AWWA Research Foundation is to advance the science of water to
improve the quality of life. Funded primarily through annual subscription payments from over …

Optimization of aerobic processes with immobilized cell reactors has proved very difficult
due to the problem of providing sufficiently high oxygen transfer rates to the immobilized …

Silicone oils were microencapsulated within polyamide (nylon) membranes cross‐linked
with polyethylenimine for use as an oxygen carrier in aerobic fermentation. The use of 20 …

A novel method for supplying oxygen by using a perfluorocarbon as an oxygen carrier in
submerged cultures was demonstrated. Oxygen was transferred to the aqueous phase by …

Bioreactor headspace pressurization represents an excellent means of enhancing oxygen
mass transfer to a culture. This method is particularly effective in situations where stirring or …

The possibility of using hydrogen-peroxide as an oxygen source in immobilized whole cell
systems was investigated. The conversion of glycerol to dihydroxyacetone performed by Ca …
