Determination of Hydroquinone Dioxygenase Activity
Bio-Protocol, 2015 We recently demonstrated the presence of a quinone detoxification pathway present in Firmicutes. It is based on two enzyme activities, namely a hydroquinone dioxygenase, YaiA, described here, and a hydroquinone reductase, YaiB, described in a separate ...

Potential of Seaweed to Improve the Quality and Shelf Life of Fish and Fishery Products
Food Safety and Health, EarlyView.Growing global demand for safe fish preservation has increased interest in natural alternatives. Seaweed‐derived bioactive compounds possess antioxidant and antimicrobial properties that enhance fish quality, safety, and shelf life. These sustainable preservatives may reduce spoilage and synthetic preservative use, though further research ...

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Upflow anaerobic sludge blanket (UASB) reactors are widely used in low‐ and middle‐income countries, but secondary effluents may still contain organic micropollutants and residual toxicity. This study evaluated UV–Vis photolysis and UV/H2O2 as post‐treatment options for UASB secondary effluent (SE), integrating micropollutant ...
