Effects of temperature on biofilm formation and resource recovery during anoxyphototrophic treatment of fuel‐synthesis wastewater

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Fuel‐synthesis wastewater (FSW), a byproduct of the Fischer‐Tropsch process, requiring efficient treatment and resource recovery strategies. This study aimed to optimize temperature conditions for purple non‐sulfur bacteria (PNSB) biofilm formation and bioproduct recovery while simultaneously treating FSW. Experiments were conducted

Potential pitfalls when using popular chemical extractions to characterize Al‐ and Fe‐containing soil constituents

Journal of Plant Nutrition and Soil Science, EarlyView.
Abstract Wet‐chemical extraction of soil to quantify pedogenic species or to remove specific compounds prior to other analyses is an established approach in analytical soil mineralogy and soil chemistry. Interpretation and informational value of data derived from long‐established and frequently used extractions, for instance involving dithionite ...
