“…The microalgal-derived bioelectrochemical devices offer great potential to generate oxygenated conditions by consuming atmospheric CO 2 and light through photosynthesis. Using the algal biomass/cells as biocathodes and bioanodes can provide a sustainable production of bioelectricity. − Apart from bioelectricity, the assimilation of nutrients from wastewater offers an additional benefit of algal-based MFCs to utilize the generated biomass for biodiesel/bioethanol production. In fact, with recent technological advancements, effective utilization of even harmful algal blooms to generate bioelectricity was performed using Microcystis aeruginosa biomass as an electron donor in a MFC .…”

The fuel crisis with the slumping reserves of fossil fuels and the exponential increase in the demand of energy necessitate a paradigm shift to a more sustainable and eco-friendly energy system. Microalgal biofuel has been recognized as one of the most prominent and versatile alternative renewable energy sources because it can be converted into a wide array of biofuels, such as biodiesel, bioethanol, bioelectricity and biogases such as syngas, methane, hydrogen, and hythane etc., with a lower carbon emission profile. To attain the economic viability of algal fuels, a collective biorefinery approach addressing both the operational and technical limitations is quintessential. The current review critically analyzes and categorizes energy aspects of microalgae through various direct and indirect approaches with the perspective of a circular economy. These approaches include complicated thermochemical and biochemical processes integrating the recovery of a wide range of value-added products apart from biofuels, thus defining a cascading approach for a multiproduct-based biorefinery model. A glimpse of recent technological advancements comprising hybrid cultivation systems, prospects of co-culturing, and the role of automated/modeling approaches in the industrial-scale production of "algal-based bioenergy" is also discussed in detail. Further, the review has also scrutinized and highlighted the developments and bottlenecks in genetic and molecular aspects of strain improvement for bioenergy production. Furthermore, the study also correlated the socioeconomic and environmental impacts of producing this green energy by evaluating the prospects and pitfalls to obtain a holistic picture on this alternative fuel for a bio-based sustainable economy.

“…However, by following these methods, some problems such as a long processing time [44], [45] or demanding specific devices [46], [47] will be met. Thus, an easier method to get the algae growth status based on the electricity that generates through the proton exchange membrane [50] was proposed in this work.

In this work, a complementary metal-oxidesemiconductor (CMOS) algae growth period monitor is newly investigated for algaculture applications. The proposed monitor includes an algae sensor and a CMOS converter. The proposed monitor can transform the algae growth period into a duty cycle linearly. Through the duty cycle of the proposed CMOS converter, the algae growth status could be easily and quickly obtained. In addition, in order to be adaptively utilized in different kinds of algae growth environments, the proposed CMOS converter has a wide differential rail-to-rail voltage to the current converter and the adjustment sensitivity circuits. The measured wide-range differential rail-to-rail voltage of the CMOS converter was from −1.5 to 1.5 V, and the range of output duty cycle corresponded from 1.04% to 99.3%. The sensitivities could be varied to 41.21%/V, 32.8%/V, 27.38%/V, and 23.5%/V, respectively. The measured range of algae growth period was 1 to 5.5 days, and the range of output duty cycle was 24.96%-90.19% under different concentrations of algae nutrients (0.6‰, 0.8‰, and 1‰). A 0.49% of the measured maximum linear error was obtained. Lastly, two types of algae (Nannochloropsis sp. and Isochrysis galbana) were experimented. Convinced by the measurements and experiments, the proposed CMOS algae growth period monitor had correct functionalities for algaculture applications.
