Special Issue Information

Dear Colleagues,

The growing concerns about the depletion of fossil hydrocarbon resources, global warming and energy security have led to a resurgence of scientific interest in developing a greener approach for the production of biofuels, bioenergy, biopharmaceuticals and other value-added bioproducts from renewable bioresources, such as solid waste and wastewater, using microbial biotechnology. Such production processes are considered sustainable as they promote sustainable waste management, reduce dependency on fossil fuels, reduce greenhouse gas emissions and support the transition to a circular economy. However, it is important to ensure that microbial applications are being continuously developed to increase efficiency, are cost-competitive with conventional fossil-based technologies, and are effectively transitioned from laboratory research to pilot trials and full-scale implementation.

This Special Issue aims to collate research on the innovative applications utilizing natural or synthetic microbial communities to produce bioelectricity, gaseous and liquid biofuels, biopharmaceuticals and biomaterials, or on the other numerous bioprocesses for sustainable resource and energy recovery from various waste and waste streams.

We look forward to receiving your contributions.

This study investigated the effects of single Fenton and Fenton and UV combined processes on the cracking degree of anaerobic sludge under the same conditions. The optimal experimental conditions were obtained by repeated determination of Fe2+ dosage, H2O2 dosage and reaction time, so as to achieve the maximum cracking of sludge. In addition, this study applied three-dimensional fluorescence spectrum analysis technology to analyze the organic matter leached from the treated sludge, and different regions of the three-dimensional fluorescence spectra were analyzed and compared for each treatment condition. Repeated experiments showed that the optimal conditions for Fenton are a pH of 3, reaction time of 40 min, 1.4 g/L of Fe2+ and 9 g/L of H2O2. The Fenton process cracking yielded a protein concentration of 0.66 mg/L and sCOD of 5489 mg/L, and the UV-Fenton pretreatment yielded a protein concentration of 0.74 mg/L and sCOD of 5856 mg/L. The sludge particle size was reduced from the original 54.52 mm to 40.30 mm and 36.37 mm, respectively. In addition to these parameters, it was also demonstrated that the Fenton process has a strong cracking effect on sludge by indicators such as the SEM and sludge water content and that UV irradiation can play a role in assisting and helping sludge cracking.
