Summary: In this study, a novel internally illuminated mirror photobioreactor (IIM-PBR) was designed to improve microalgae biomass production through providing a homogenous light distribution in cultivation medium. The IIM-PBR increased microalgae growth rate up to 60 % and 30% compared to internally illuminated control photobioreactor (IIC-PBR) and externally illuminated control photobioreactor (EIC-PBR) respectively. Moreover, the IIM-PBR significantly improved nutrients removal and increased total bioproducts production by 89% and 46% compared to IIC-PBR and EIC-PBR, respectively. It also resulted in a significant reduction in total energy consumption (-10 times).

Summary: This study uses Computational Fluid Dynamics and a dynamic photosynthesis model to analyze the efficiency of photosynthesis in different sizes and circulation velocities of tubular photobioreactors. The smallest diameters of reactors were found to have sufficient radial mixing for enhancing photosynthesis under optimal light regime, while high circulation velocities in larger diameters increased operating costs without enhancing photosynthetic productivity. The characteristic frequency of the strain (beta) was shown to be crucial for high productivity.

Summary: A novel flat-plate photobioreactor with inclined baffles was developed for high-density algae cultivation. Computational fluid dynamics model optimization showed that inclined baffles with a small angle could improve swirl flow and light regime performance, with the ratio of the baffle opening distance to the reactor width being a key parameter for light regime performance. Experiments demonstrated a significant increase in algal biomass with the optimal baffle parameters compared to reactors without baffles or with horizontal baffles.

Summary: It is argued in this communication that a high maximal growth rate is not necessarily sufficient or necessary for high phototrophic productivity. Rather, the specific growth rate of a phototrophic microorganism is determined by factors such as light absorption rate, photosynthetic efficiency, and biomass yield per mol photons. Therefore, besides maximal growth rate, photosynthetic efficiency and maximal biomass yield should also be considered as predictors of culture productivity when evaluating fast-growing strains.

Summary: Industrial wastewater containing heavy metals, nutrients, and soluble salts can cause eutrophication in water bodies. Microalgae biomass has the potential to produce various valuable products, but the high production cost and sensitivity of cultivation parameters limit its global output. Combining microalgae cultivation with wastewater treatment, particularly in photobioreactors, can reduce operating costs. However, there is a limited amount of research on using industrial wastewater for microalgae cultivation in photobioreactors. Therefore, optimizing cultivation parameters using industrial wastewater in photobioreactors is crucial.

Summary: Microalgae and microalgae-derived ingredients are a top trend in the food industry, but consumers' acceptance and purchase intention can be influenced by odor and flavor. Surprisingly, there are limited studies on the volatile composition of microalgae and cyanobacteria. This study aimed to investigate the volatile composition of seven microalgal and cyanobacterial strains from marine and freshwater sources and understand their potential impact on odor. The results showed that the composition of volatile organic compounds (VOCs) is mainly driven by the individual strain, but can also be influenced by environmental and taxonomical factors.

Summary: The present study aimed to evaluate the use of microalga Scenedesmus almeriensis for treating untreated urban wastewater. Two 12 m(3) raceway reactors, one supplemented with wastewater and the other with chemical fertilizer, were operated outdoors in a semi-continuous mode for eight months. The results showed that S. almeriensis could be produced in wastewater without affecting the photosynthetic apparatus, with an average productivity of 13 g center dot m(-2)center dot day(-1) in both systems. Moreover, the nutrient content of the wastewater, including nitrogen, phosphorous, and chemical oxygen demand, was reduced to meet European limitations, with average removal rates of 2.2, 0.2, and 3.0 g center dot m(-2)center dot day(-1) respectively. The raceway reactors demonstrated high potential for microalgal production and efficient biotreatment, proving to be robust and reliable. Additionally, an accurate model was developed to evaluate the effect of environmental conditions on biomass productivity in the clean system (R-2 = 0.9, p = 0.0002).

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
