Series-connected data-based model to estimate effluent chemical oxygen demand in industrial wastewater treatment process.

Continuous monitoring of chemical oxygen demand (COD) is essential to ensure efficient and sustainable wastewater treatment and regulatory compliance. However, traditional hardware measurements are laborious, infrequent and costly. In this research, a cost-effective real-time alternative is presented.

Modification of buffered peptone water for improved recovery of heat-injured Salmonella Typhimurium.

Rapid detection of Salmonella in foods is often limited by the high demand for the sensitivity of detection, poor physiological conditions of the target cells, and high concentration of background flora. In this study, the conditions of nonselective enrichment cultivation were modified in order to improve the quantitative detection of heat-injured Salmonella in minced meat. The effect of the modifications on the recovery was observed by means of RNA-based sandwich hybridization, which was adjusted for the quantification of Salmonella enterica 23S rRNA in crude cell extracts.
