Evaluation of growth, nutrient utilization and production of bioproducts by a wastewater-isolated microalga.

Treatment of wastewater while producing microalgal biomass is receiving ever-increasing attention, particularly in the biofuels arena. In this study, a wastewater chlorophyte isolate, Kirchneriella sp., was tested for its ability to be mass cultivated, utilize nutrients from defined media and wastewater, and produce bioproducts of commercial interest.

Potential alteration of U37K' paleothermometer due to selective degradation of alkenones by marine bacteria isolated from the haptophyte Emiliania huxleyi.

The unsaturation ratio of C(37) alkenones (U(37)(K')) produced by haptophyte microalgae such as Emiliania huxleyi is often used as proxy for past sea surface temperature. In this study, 29 bacterial strains were isolated from cultures of the strain E. huxleyi TWP1.
