“…Recent studies aim at improving the batch culture by optimizing the light supply so that the phenomena of photolimitation and photoinhibition are reduced, [3,8,14,17]. It was concluded that an incremental light supply reduces energy consumption compared to a conventionally operated PBR, for the same cell production.…”

“…These reactors are operated in continuous 2 or discontinuous mode. 3 Efficient operation of PBRs poses specific challenges in terms of process control. In all cases, considering light as a "substrate" for growth, its distribution inside the bulk governs the performances of the production system.…”

International audienceThis chapter proposes the optimization of batch microalgae cultures in artificially lighted photobioreactors . The strategy consists in controlling the incident light intensity so that the microalgae growth rate is maximized. Two approaches were developed and compared. In the first one, the ratio between the incident light intensity and the cell concentration (light-to-microalgae ratio) is optimized, either offline or online, and then maintained at its optimal value. In the second approach, the cells growth rate is maintained at its optimal value by means of nonlinear model predictive controller (NMPC). The proposed control strategies are illustrated and their efficiency is assessed, in simulation, for Chlamydomonas reinhardtii batch cultures. The proposed lumostatic operation strategies are shown to lead to a higher cell productivity and to a more efficient light utilization in comparison to conventional constant light operation approach

Microalgae are foreseen as a promising alternative source to produce biodiesel due to the potential high oil content in their cells and fast generation to yield a higher biomass. Hence, this study is focused in exploring the feasibility and potential of a locally isolated C. vulgaris strain in producing biodiesel. This comprises of cell growth, biomass productivity, lipid extraction and biodiesel analysis. The results show that C. vulgaris growth is influenced by light intensity whereby cultures illuminated with 2000 lux produces the highest number of cells and biomass. It is found that the combination of chloroform/methanol solvent extracts higher amount of lipid compared to hexane/ether or hexane. The biodiesel produced complies with ASTM standards. Based on this study, C. vulgaris strain is found to be a viable feedstock in the production of biodiesel. © 2015 American Institute of Chemical Engineers Environ Prog, 34: 1215–1220, 2015

In article number 1903707, Yu‐Cheng Chen and co‐workers demonstrate an approach to amplify bio‐nano‐electricity through the encapsulation of living algae in an optical micro‐cavity. The strong energy coupling between the cavity mode and photosynthetic resonance reveal the potential of exploiting optical resonators to amplify biological photocurrent generation and energy‐harvesting efficiency. Potential applications include photocatalysis, electrochemistry, and sustainable biophotonics.
