    Notes:
    Transmission versus voltage operating characteristics of a GaAs/AlGaAs multiple-quantum-well light modulator have been measured at temperatures between 4.3 and 290 K. At 4.3 K, the linewidth of the heavy-hole exciton absorption is 1.3 meV, and the modulation ratio is greater than 1000 at a 9-V bias. At room temperature, the exciton resonance is broadened to 5.3 meV by phonon scattering and the maximum modulation ratio is 4.93 at 12 V. The measured temperature and voltage dependence of the exciton absorption energies, linewidths, and intensities have been used with a simple model for the modulator's optical transmission to calculate the operating characteristics as a function of material quality. The upper limit on the room-temperature transmission modulation ratio is estimated to be 5.4 for a device fabricated from 100 quantum wells of width 100 A(ring).

    Notes:
    The production of ethanol from cheese whey lactose has been demonstrated using a single-stage continuous culture fermentation with 100% cell recycle. In a two-step process, an aerobic fed batch operation was used initially to allow biomass buildup in the absence of inhibitory ethanol concentrations. In the anaerobic ethanol-producing second step, a strain of Kluyveromyces fragilis selected on the basis of batch fermentation data had a maximum productivity of 7.1 g ethanol/L/h at a dilution rate of 0.15 h-1, while achieving the goal of zero residual sugar concentration. The fermentation productivity diminished when the feed sugar concentation exceeded 120 g/L despite the inclusion of a lipid mixture previous shown to enhance batch fermentation productivities.
