Performance of a pilot-scale packed bed reactor for perchlorate reduction using a sulfur oxidizing bacterial consortium.

Amber R Boles et al.

Biotechnology and bioengineering, 109(3), 637-646 (2011-10-22)

A novel sulfur-utilizing perchlorate reducing bacterial consortium successfully treated perchlorate (ClO₄⁻) in prior batch and bench-scale packed bed reactor (PBR) studies. This study examined the scale up of this process for treatment of water from a ClO ₄⁻ and RDX contaminated

Comparison of common lignin methods and modifications on forage and lignocellulosic biomass materials.

Ben M Goff et al.

Journal of the science of food and agriculture, 92(4), 751-758 (2011-11-19)

A variety of methods have been developed for estimating lignin concentration within plant materials. The objective of this study was to compare the lignin concentrations produced by six methods on a diverse population of forage and biomass materials and to

Glyceraldehyde-3-phosphate dehydrogenase: a universal internal control for Western blots in prokaryotic and eukaryotic cells.

Yonghong Wu et al.

Analytical biochemistry, 423(1), 15-22 (2012-02-14)

In the current study, we examined the expression level of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) protein in a number of organisms and the stability of GAPDH under various conditions. Our results revealed that GAPDH is present in multiple Escherichia coli strains, the
