Containment cells

In general, pilot-plant space can be divided into five basic types separate buildings, containment cells or barricades, open bays, walk-in hoods, and laboratory areas. A summary of the advantages and disadvantages of each has been given (1). 

Determine if placing the process reactor in a containment cell will significantly reduce risk. 

A fermentation broth containing Streptomyces kanamyceticus cells is filtered by a vacuum rotary filter. The feed rate is 120kg h1 each kilogram of broth contains 60g of cells. To improve filtration, filter aids are added at a rate of 10kg-h. The concentration of kanamycin in the broth is 0.05%. The filtrate is collected at a rate of 112 kg h. The concentration of kanamycin in the filtrate is 0.045%. The filter cake contains cells, and filter aid is continuously removed from the filter cloth. 

The burner is operated on natural gas and air in a fuel-rich mode. Fluorine reacts with excess fuel to form HF and CF4. All of the air that goes through the containment cell (hood) is scrubbed with caustic before being released. (We considered destroying the fluorine by reaction with caustic, but our calculations suggested that this reaction was too slow.)...

Expanded-bed adsorption (ERA) has gained popularity in bioprocessing since its commercial introduction in the 1990s because of its ability to handle a crude feedstock that contains cells or other particulates. ERA ehminates the need for a dedicated clarification step by combining sohd-hquid separation and adsorption into a single-unit operation [Hjorth et al., in Subramanian (ed.), op. cit., vol. 1, pp. 199-226 Mattiasson et al., in Ahuja (ed.), op. cit., pp. 417-451].

Human leukocyte antigens (HLA) Groups of genes found on the major histocompatibility complex, which contain cell-surface antigen-presenting proteins. The body uses HLA to distinguish between self-cells and non-self-cells. 

In the inductive mode the magnetic permeability of a solution-containing cell placed in the field of an inductance coil represents the measuring principle of the method however, this property is not very sensitive to differences in solution composition, so that the inductive mode still remains of limited applicability. 

DA-containing cells project into the basal ganglia and the frontal cortex ... 

The cause of the orexin-containing cell loss in typical narcolepsy-cataplexy remains unknown, but the HLA association is intriguing because it suggests that autoimmunity could mediate a central disease process. This is not...
