Biological hydrogen production of the genus Clostridium: Metabolic study and mathematical model simulation
Abstract The biochemical hydrogen potential (BHP) tests were conducted to investigate the metabolism of glucose fermentation and hydrogen production performance of four Clostridial species, including… Expand

Investigation of potential application of surfactin and rhamnolipid in stimulating indigenous microorganisms for enhanced bioremediation of diesel-contaminated water and soil confirmed their enhancing capability on both efficiency and rate of diesel biodegradation in diesel/soil systems. Expand
Competition between polyphosphate- and glycogen-accumulating organisms in enhanced-biological-phosphorus-removal systems: effect of temperature and sludge age.
Temperature and sludge age were found to be important factors in determining the outcome of competition between polyphosphate-accumulating organisms (PAOs) and glycogen-accumulating non-polyphosphate… Expand
Bioremediation of petroleum hydrocarbon contaminated soil: Effects of strategies and microbial community shift
Abstract Biodegradation of petroleum hydrocarbon oil (14,000 mg kg −1 ) were investigated in six biopiles batches, differing in the remediation strategy: bioaugmentation (selected consortium and… Expand
Biological treatment of thin-film transistor liquid crystal display (TFT-LCD) wastewater using aerobic and anoxic/oxic sequencing batch reactors.
Batch studies on biodegradation rates for DMSO, MEA, and TMAH under anaerobic, anoxic, and aerobic conditions indicate that effective MEA degradation can be easily achieved under all three conditions examined, while efficient DMSo and T MAH degradation can been attained only under an aerobic and aerobic Conditions, respectively.

Nitrifying community structures and nitrification performance of full-scale municipal and swine wastewater treatment plants.
The results suggest that the swine nitrifying sludge, involving relatively diverse AOB and NOB populations that perform the same task but with distinct growth and survival characters, may allow communities to maintain nitrify capabilities when conditions change such as sudden increases in ammonium concentrations as examined with nitrification kinetic batch tests.

The effect of pH on the production of biohydrogen by clostridia: Thermodynamic and metabolic considerations
Abstract This study evaluates the effect of pH (4–7) on fermentative biohydrogen production by utilizing three isolated Clostridium species. Fermentative batch experiments show that the maximum… Expand
Biological treatment of TMAH (tetra-methyl ammonium hydroxide) in a full-scale TFT-LCD wastewater treatment plant.
Based on batch experiments, inhibitory chemicals present in TFT-LCD wastewater like surfactants and sulfate should be avoided to secure a stable methanogenic TMAH degradation. Expand
Competition between polyphosphate- and glycogen-accumulating organisms in biological phosphorus removal systems--effect of temperature.
It is demonstrated that temperature is an important factor in determining the outcome of competition between polyphosphate-accumulating organisms (PAOs) and glycogen- Accumulating non-poly-P organisms (GAO) and the resultant stability of enhanced biological phosphorus removal (EBPR) systems and the eventual failure of EBPR processes at high temperatures.
