Uranium accumulated extracellularly on the surfaces of Saccharomyces cerevisiae cells. The rate and extent of accumulation were subject to environmental parameters, such as pH, temperature, and interference by certain anions and cations. Uranium accumulation by Pseudomonas aeruginosa occurred intracellularly and was extremely rapid (<10 s), and no response(More)
Columnar reactors containing immobilized cells of Zymomonas mobilis were utilized for the continuous production of ethanol from glucose. Two different immobilization strategies were investigated. In one case, cells were entrapped in borosilicate glass fiber pads, while in the other, cells were immobilized via flocculation. The reactors were operated in both(More)
A prototype centrifugal system has been developed that permits parallel photometric monitoring of eluate streams from a radial array of chromatographic columns. The modular rotor design consists of a discoidal center insert for eluent and sample apportionment, the chromatographic columns, and flow-through cuvetts-all mounted on an aluminum base plate.
