In this study, the Pb2+ biosorption potential of live and dead biosorbents hydrocarbon-degrading strain Rhodococcus sp. HX-2 was analyzed. Optimal conditions were determined via single factor optimization, which as follows: temperature, 25°C; pH, 5.0, biosorbent dose, 0.75 g L-1. A response surface software (Design Expert 10.0) used to analyze optimal conditions. The data for suitable Freundlich model at a concentration 200 mg At same concentration, maximum capacity 88.74 g-1 (0.428 mmol g-1) 125.5 (0.606 biosorbents. Moreover, in comparison with pseudo-first-order model, pseudo-second-order seemed better depict process. Dead have lower binding strength than biosorbents, showing higher desorption pH 1.0. order influence competitive metal ions on adsorption Cu2+ > Cd2+ Ni+. Fourier-transform infrared spectroscopy analyses revealed that several functional groups involved process Scanning electron microscopy showed attached more readily whereas transmission confirmed transfer biosorbed into cells case both It can thus be concluded are biosorption, they accordingly wastewater treatment.

Fruit-Based Fermented Beverages: Contamination Sources and Emerging Technologies Applied to Assure Their Safety

Foods, Journal Year: 2023, Volume and Issue: 12(4), P. 838 - 838

Published: Feb. 16, 2023

The food and beverage market has become broader due to globalization consumer claims. Under the umbrella of demands, legislation, nutritional status, sustainability, importance safety must be decisive. A significant sector production is related ensuring fruit vegetable conservation utilization through fermentation. In this respect, in review, we critically analyzed scientific literature regarding presence chemical, microbiological physical hazards fruit-based fermented beverages. Furthermore, potential formation toxic compounds during processing also discussed. managing risks, biological, physical, chemical techniques can reduce or eliminate any contaminant from Some these belong technological flow obtaining beverages (i.e., mycotoxins bound by microorganisms used fermentation) are explicitly applied for a specific risk reduction mycotoxin oxidation ozone). Providing manufacturers with information on that could jeopardize drinks strategies lower paramount importance.
