Special Issue Information

Dear Colleagues,

Bioprocesses are employed in various fields, including the manufacturing of chemicals, pharmaceuticals, food, feed, and energy. Therefore, the monitoring of bioprocesses is essential for their efficient operation and effective control.

This Special Issue, entitled "Advances in Bioprocess Monitoring and Control", aims to highlight novel strategies that facilitate the monitoring and control of a variety of bioprocesses. The scope of this Special Issue includes, but is not limited to, the following topics:

  • Waste valorization;
  • Wastewater treatment;
  • Pharmaceutical bioprocesses;
  • Stem cell bioprocesses;
  • UV–Vis spectroscopy;
  • NIR spectroscopy;
  • Raman spectroscopy;
  • NMR spectroscopy;
  • Flourescence spectroscopy;
  • Flow cytometry;
  • Biosensors;
  • Microfluidics and microanalysis;
  • Optical sensors.

Aquaponics offers a simple conclusive solution to the food and environmental crisis around the world. This paper presents a comparative analysis of standard aquaponics with vermiponics (aquaponics with earthworms) before and after applying an optimal freshwater replenishment. Fish and plants were grown on a standard aquaponics testbed and a vermiponics testbed for 3 months each, initially without water replenishment, and then with 19% replenishment based on the fishtank volume. Water quality and environmental data were monitored, collected and processed using sensors and internet of things (IoT) devices. Daily growth analysis, the mean productivity of both testbeds before and after replenishment, the percentage of productivity difference and the general productivity comparison between standard and vermiponics testbeds were determined. Results showed an enhanced productivity of 2.83% and 5.54% for the standard testbed and the vermiponics testbed, respectively, when replenishment was applied. The yield improvement after replenishment was proven to be statistically significant, with p < 0.05 reassuring the impact of water replenishment. This research contributes to the understanding of the impact of water replenishment in aquaponics and vermiponics systems. Moreover, it provides insights into the effect of earthworms on both systems’ yield productivity. Full article

There is a growing recognition that food waste (FW) comprises a significant amount of unused energy. Indeed, FW shows great potential to produce methane (CH4)-rich biogas via an anaerobic digestion (AD) process. Nevertheless, to ensure high AD process performance, deepening the knowledge of FW characteristics is required. Furthermore, the biogas yield is strongly influenced by several operational parameters. Taking into account the above, in the current study, based on the data in the literature, the physicochemical parameters of FW generated throughout the world are presented and discussed. In addition, the performance profile of the single-stage anaerobic mono-digestion process with the use of FW as a feedstock was investigated. The performed analysis clearly demonstrated that FW is characterized by significant variations in several parameters, such as pH, the total solid (TS) and volatile solid (VS) contents, the volatile solids to total solids ratio (VS/TS), soluble chemical oxygen demand (sCOD), the concentrations of VFAs and ammonium nitrogen (NH4+-N), and the carbon-to-nitrogen ratio (C/N). Moreover, it was shown that the selected operational parameters, such as temperature, pH, the ratio of food waste to inoculum (I) (FW/I), and the organic loading rate (OLR), may have the most significant impact on the performance of the single-stage anaerobic mono-digestion process. In addition, it was found that most of the experimental investigations presented in the literature were conducted on a laboratory scale. Hence, in future research, more effort should be made to determine the biogas yield with the use of full-scale systems. To summarize, it should be clearly highlighted that the analysis presented in this study may have important implications for the management and application of FW as feedstock for an anaerobic mono-digestion process on an industrial scale.
