  Tubular and the flat plate are the two most common general designs of microalgal photobioreactors. Desired photobioreactors for microalgal mass production have effective liquid mixing to promote nutrients mixing and gas mass transfer; have adequate surface area for light capture; prevent significant accumulation of oxygen; allow for ease of scale-up; and have low material and maintenance costs, among others. The higher, more stable productivity, the markedly reduced incidence of significant culture contamination, and the greater land- and water-use efficiencies constitute the principal reasons why photobioreactors are considered favorable for the scaled-up production of microalgal biomass for biofuel production compared with open raceways. The principal goal of the photobioreactor scale-up process is to ensure that the desired level of microalgal productivity is maintained as the volume of production transitions from small laboratory scale to intermediate pilot scale, all the way to the large industrial scale. This necessitates that the characteristic hydrodynamic conditions (e.g., degree of mixing) and the accompanying environmental conditions (e.g., lighting) of the specific type of photobioreactor used are maintained or appropriately adjusted with increasing production volume to maintain the desired level of microalgal productivity. The scale-up process of cultivating a specific algal species in a specific photobioreactor is thus the stage-by-stage optimization or reoptimization of the culture with the goal of ensuring that the desired level of microalgal productivity is maintained with each increase in scale.

  More info

  Tertiary-treated effluent from a municipal wastewater treatment plant in Tucson, AZ, was added to recirculating hydroponic bed bioreactors filled with light expanded clay aggregate (LECA) and recirculated for 10 days. Bioreactors were planted with high and low densities of sorghum (Sorghum bicolor), switchgrass (Panicum virgatum) and Bacillus thuringiensis cotton (Gossypium sp.). The experiment also included a non-planted bioreactor treatment and a control bioreactor with neither plants nor substrate medium. Of 46 contaminants of emerging conern assayed with liquid chromatography tandem mass spectrometry (LC-MS/MS), 16 were initially identified at detectable levels in the effluent. After one day, concentrations of Ibuprofen and Diphenhydramine fell below detection limits in all treatments as well as the control. After five days, initial concentrations of atenolol, benzotriazole, carbamazepine, hydrochlorothiazide, iohexol, iopamidol iopromide, primidone, sulfamethoxazole and tris TCPP were reduced by greater than 80% in all treatments, while the control exhibited little to no removal. Diclofenac, simazine and sucralose exhibited variable removal rates among treatments ranging from 44 to 84% after five days. After 10 days, concentrations of DEET, diclofenac, iopromide, primidone and simazine were all below detection levels, while there was near zero removal in the control. Bioreactors planted with cotton had significantly more removal of sulfamethoxazole than unplanted bioreactors by 16-19% after five days and by an additional 18-20% removal after 10 days. The percentage uptake of benzotriazole by every planted treatment was significantly higher than the non-planted treatment after five and 10 days. Significant contaminant removal occurred in the media substrate, likely through adsorption to LECA or microbial degradation. More research is needed to examine specific pathways of degradation and removal by various microbials and plants.

  More info

  A new strategy in photosynthetic hydrogen (photo-H(2)) production from green algae was developed based on theory and successfully demonstrated. The new strategy applied a spectral-selective photosystem I (PSI) activating/photosystem II (PSII) deactivating radiation (or PSI light) that would drive a steady flow of electrons in the electron transport chain for delivery to hydrogenase for photo-H(2) production, but would reduce oxygen production through water photolysis below the respiratory oxygen consumption so that an anoxic condition would be maintained as required by hydrogenase. Implementing the strategy by using a PSI light (692 nm peak, 680-700 nm) on Chlamydomonas reinhardtii cells resulted in relatively sustained photo-H(2) production (total of 0.108 mL H(2)mg(-1)Chl, exceeding 0.066 mL H(2)mg(-1)Chl under white light). The strategy also proved successful and convenient in allowing cells to alternately switch between photo-H(2) production and a recovery period by simply turning on or off the PSI light.
