Special Issue Information

Dear Colleagues,

This Special Issue, titled "Bioprocess Engineering and Fermentation Technology", will focus on the latest developments in sustainable bioprocesses for the production of commercial products that have been widely used in food, cosmetics, chemical, pharmaceutical, and biofuel industries via advanced fermentation technologies using microbial cells. Every year, new products are added to the list of compounds derived through various biochemical conversion routes, which is an alternative to classical chemosynthesis routes. In order for these bioprocesses to be commercially feasible at an industrial scale, several issues need to be addressed, from upstream processing and  fermentation, to downstream processing stages by integrating different fields of bioengineering, and at the same time taking into consideration minimizing the impact of these processes on the environment.

Over the years, significant improvements on the overall process performance have been accomplished using various strategies and techniques, including strain improvement via metabolic engineering and adaptive evolution, and by applying different modes of fermentation, such as cell immobilization and fermentation with in situ product recovery (ISPR). Examples of techniques employed for ISPR are extraction and evaporation, electrodialysis, membrane separation, and adsorption.

This Special Issue is devoted to highlighting the recent developments and innovations in microbial bioprocessing. We would like to invite authors to submit both original research and state-of-the-art critical reviews within the scope of the Special Issue, which includes, but is not limited to, strategies that improve the final product titers, yields, and productivities of the bioproducts; overcome the challenges in product recovery; and improve the efficiency and economy of the bioprocesses. Recent advances in thermochemical and chemical pretreatment methods of biomass are also welcome for this Special Issue.

A thermosiphon photobioreactor (TPBR) can potentially be used for biohydrogen production, circumventing the requirement for external mixing energy inputs. In this study, a TPBR is evaluated for photofermentative hydrogen production by Rhodopseudomonas palustris (R. palustris). Experiments were conducted in a TPBR, and response surface methodology (RSM), varying biomass concentration, and light intensity and temperature were employed to determine the operating conditions for the enhancement of both hydrogen production as well as biomass suspension. Biomass concentration was found to have had the most pronounced effect on both hydrogen production as well as biomass suspension. RSM models predicted maximum specific hydrogen production rates of 0.17 mol m−3h−1 and 0.21 mmol gCDW−1h−1 at R. palustris concentrations of 1.21 and 0.4 g L−1, respectively. The experimentally measured hydrogen yield was in the range of 45 to 77% (±3.8%), and the glycerol consumption was 8 to 19% (±0.48). At a biomass concentration of 0.40 g L−1, the highest percentage of biomass (72.3%), was predicted to remain in suspension in the TPBR. Collectively, the proposed novel photobioreactor was shown to produce hydrogen as well as passively circulate biomass. Full article

Third generation biofuels and high-value bioproducts produced from microalgal biomass have been considered promising long-term sustainable alternatives for energy and/or food production, potentially decreasing greenhouse gas emissions. Microalgae as a source of biofuels have been widely studied for bioethanol/biodiesel/biogas production. However, critical research is needed in order to increase the efficiency of microalgae production from high-N agri-waste, not only for biofuels but also for bio-based products, and thus enhance its commercial viability. The growth in the poultry industry has led to increased chicken manure (CM), which are rich in ammonia, phosphate, potassium, and other trace elements. These constituents could be used as nutrients for growing microalgae. In this research, a two-stage (liquid–solid) anaerobic digester treating CM at 20 ± 1 °C was performed, and liquid digestate (leachate) obtained after the digestion process was used as a substrate to grow the microalgal strain Chlorella vulgaris CPCC 90. Considering the high-N content (NH3-N: 5314 mg/L; TKN: 6197 mg/L) in liquid digestate, different dilutions were made, using distilled water to obtain viz. 10%, 30%, 50%, 70%, 90%, and 100% of the digestate concentrations for the microalgae cultivation. Preliminary results showed that Chlorella vulgaris CPCC 90 was able to grow and utilize nutrients from a 10% diluted CM digestate. Future research is underway to enhance microalgal growth at higher digestate concentrations and to optimize the use of microalgae/microalgae-bacteria consortia for better adaptation to high-N content wastes. An AD-microalgae coupling scenario has been proposed for the circulation bioeconomy framework. Full article
