Demystifying polyphosphate-accumulating organisms relevant to wastewater treatment: A review of their phylogeny, metabolism, and detection.

Currently, the most cost-effective and efficient method for phosphorus (P) removal from wastewater is enhanced biological P removal (EPBR) via polyphosphate-accumulating organisms (PAOs). This study integrates a literature review with genomic analysis to uncover the phylogenetic and metabolic diversity of the relevant PAOs for wastewater treatment. The findings highlight significant differences in the metabolic capabilities of PAOs relevant to wastewater treatment.

Evaluation of nutritional composition and technological functionality of whole American Bullfrog (Lithobates catesbeianus), its skin, and its legs as potential food ingredients.

Frog farming systems do not take advantage of their byproducts, which represents health risks and environmental pollution. The present study aimed to evaluate the proximate composition, amino acid, and fatty acid profile of American Bullfrog byproducts (whole frogs (WF), legs (LF), and skin (SF)) and their technological functionality. Results showed that WF, LF, and SF protein content was 47.
