Mixing fffects in coal processing bioreactors

Abstract: In the bioprocessing of high-volume, low-value products like coal it is important to minimize the size and cost of the bioreactor. Optimum reactor design requires attention to the degree to which mixing should be induced or prevented. An analysis of a simple bioprocess in plug-flow and stirred-tank reactors shows that the amount of mixing required depends critically on the amount of microorganisms available from the inoculum and from cell growth. A mixed reactor is preferable when microbes are scarce and is the only possible solution when none are available to inoculate the coal entering the reactor. However, when sufficient cells are available (usually from cell recycling) a plug-flow reactor may be an order of magnitude smaller. The best solution may be a stirred-tank reactor feeding a plug-flow reactor and reactor size estimates for this system are given.

Bioreactor development with respect to process constraints imposed by bio-oxidation and waste remediation

Abstract: Bioreactors serve a central role in biotechnological processes by providing the link between starting materials and final products. In most biological systems, there are complex series of reactions that must be optimized and coordinated in a very specific environment. Despite the complexity of biocatalytic processes, there is usually a rate-limiting step controlling the reaction, as well as a few secondary limitations. These limitations provide the basis for process design and bioprocess equipment specifications. The EIMCO Slurry Bioreactor has been designed to overcome these limitations encountered during the bio-oxidation of refractory gold ores and concentrates and hazardous waste bioremediation.
