Production and harvesting of microalgae for wastewater treatment, biofuels, and bioproducts.
Further investigation and development of large-scale production and harvesting methods for biofuels and bioproducts are necessary, particularly with less studied but promising approaches such as those involving attached algal biofilm cultures. Expand
Rotating algal biofilm reactor and spool harvester for wastewater treatment with biofuels by‐products
A novel rotating algal biofilm reactor (RABR) was designed, built, and tested to operate in the photoautotrophic conditions of open tertiary wastewater treatment, producing mixed culture biofilms made up of algae and bacteria. Expand
Fate of polynuclear aromatic compounds (PNAs) in soil-plant systems
Polycyclic aromatic hydrocarbons (PAH) consist of three or more fused benzene rings in linear, angular, or cluster arrangements. Substitution of carbon in the benzene ring with nitrogen, sulfur,… Expand
Algal biofilm based technology for wastewater treatment
Widespread application of algal biofilm-based systems in wastewater treatment has been limited despite the potential benefits of a low cost nutrient removal option and a source of biomass for… Expand
Evaluation of the use of prairie grasses for stimulating polycyclic aromatic hydrocarbon treatment in soil
Abstract A research project was conducted to evaluate enhanced treatment of toxic organic chemicals in soil using deep rooted grasses. Eight types of prairie grasses were evaluated in the treatment… Expand
Isolation and Characterization of Polycyclic Aromatic Hydrocarbon–Degrading Mycobacterium Isolates from Soil
It is found that dioxygenase genes nidA and nidB are present in each of the Libby Mycobacterium isolates and are adjacent to each other in the sequence nid B-nidA, an order that is unique to the PAH-degrading mycobacteria. Expand

Acetone, butanol, and ethanol (ABE) fermentation by Clostridium saccharoperbutylacetonicum N1-4 using wastewater algae biomass as a carbon source was demonstrated. Algae from the Logan City… Expand
Fate of PAH compounds in two soil types: influence of volatilization, abiotic loss and biological activity.
The fate of 14 polycyclic aromatic hydrocarbon (PAH) compounds was evaluated with regard to interphase transfer potential and mechanisms of treatment in soil under unsaturated conditions.… Expand
Biodiesel from mixed culture algae via a wet lipid extraction procedure.
The capability of the procedure to extract lipids from wet algal biomass, to reduce/remove chlorophyll contamination, to potentially reduce organic solvent demand, and to generate feedstocks for high-value bioproducts presents opportunities to reduce costs of scaling up algal lipid extraction for biodiesel production.

It is indicated that HA dramatically shortens the onset time for PAH biodegradation from 168 to 2 h, which will have large implications for the bioremediation of contaminated soils. Expand
