TL;DR: In this article, a real-time Bacteroides species (AllBac) detection was performed on human, cattle, and equine feces, and the results showed that the AllBac detection can be used to estimate the total amount of fecal contamination in water.

TL;DR: Real-time PCR assays using TaqMan or Molecular Beacon probes were developed and optimized for the quantification of total bacteria, the nitrite-oxidizing bacteria Nitrospira, and Nitrosomonas oligotropha-like ammonia oxidizing bacteria (AOB) in mixed liquor suspended solids from a municipal wastewater treatment plant (WWTP) using a single-sludge nitrification process.

TL;DR: This study extended the knowledge of the comparative compositions of nitrifying bacterial populations in wastewater treatment systems and demonstrated that it was able to quantify these populations, which ultimately will be required for accurate prediction of process performance and stability for cost-effective design and operation of WWTPs.

TL;DR: The importance of adapted microbial populations in the removal of estrogen was shown by the dramatic differences in mineralization of 14C-17β-estradiol by biosolids from a municipal plant compared to that from the industrial plant, 84% versus 4%, respectively.

TL;DR: Estrogen to macronutrient ratios are proportional to areal mass application rates of estrogen to fields and can be used to better predict estrogen loading rates on fields receiving swine and dairy wastes.
