“…The increase in concentrations of biomass, lipid, protein and carbohydrate has been found as 4.4, 5.3, 3.5 and 2.9‐fold for 14 days of growth. One of the probable reasons for the increase in concentration of biomass may be due to the presence of high concentration of nitrogen (nitrate) and phosphorous (phosphate) in the BG‐11 medium (Goli et al ., 2016). Researchers reported that phosphorous is one of the essential nutrients in growth (Lam et al ., 2012; Jebali et al ., 2018).…”

Sequestration of CO2 using microalgae is one of the imperative, cost effective and environment‐friendly processes for carbon sequestration and for production of biomass. In the present study, a cyanobacterial consortium was used for the sequestration of CO2 at diverse initial CO2 concentrations (5–30%), pH of the medium (7–11) and inoculum sizes (5–12.5%). The cyanobacterial consortium showed sustainability in growth upto 30% CO2. The overall CO2 fixation capacity was found as 0.0692 and 0.071 mol CO2/g algae at 15% CO2, pH 9 and at 10% and 12.5% inoculum, respectively, after 14 days. Characterization of dry biomass before and after CO2 sequestration was done using Fourier Transform Infrared spectroscopy. Various algorithm of artificial neural network (ANN) model and a number of activation functions were tried to arrive at best ANN model for such process. Finally, Particle swarm optimization was used for optimization of input variables for maximum sequestration of CO2.

“…It represents a focal challenge for mankind to preserve our planets ecosystem. To alleviate climate change effects there is a demand for innovative technologies that can actively fix and reduce atmospheric CO 2 ( Goli et al, 2016 ; Vo Hoang Nhat et al, 2018 ). Microalgae are a taxonomically diverse group of photosynthetic microorganisms which, due to their superior photosynthetic efficiency, can convert CO 2 up to ten times faster into biomass than any vascular, terrestrial plant ( Goli et al, 2016 ; Adeniyi et al, 2018 ).…”

In context of the global climate change, microalgae processes are gaining momentum as a biotechnological tool for direct fixation and valorization of greenhouse gases. Algae have the metabolic capacity to photosynthetically convert CO2 into high value products, such as food additives, under economic boundary conditions. High cost, commercial flat panel gas-lift bioreactors for microalgae cultivation at laboratory scale provide either small volumes or no sterile operation, which limits academic research. This brief report presents initial data for a new type of sterile operating flat panel gas-lift bioreactor with a unique asymmetrical U-shape. It utilizes automatable process control technologies that adhere to industrial standards to enhance data reproducibility and aid industrial scale up. The practicability was demonstrated using a Chlorella sorokiniana cultivation, which showed the typical growth behavior. Due to the sophisticated implemented control engineering technology, pivotal parameters as pH and temperature can be determined within a range of ±0.1 units, which was confirmed experimentally. The new flat panel gas-lift photobioreactor presented in this brief report fills the technology gap at laboratory scale with an autoclavable volume of 7.2 L. Moreover, it is easy to rebuild by means of the hereby provided blueprint, while exhibiting a six-fold cost reduction compared to commercially available flat panel photobioreactors.

“…The removal of CO 2 from the ambient environment can be achieved by applying a variety of physical and chemical processes such as aqueous solutions of alkanolamine absorption [6], membrane separation [7], and biological capture [8]. Chemical absorption/adsorption is regarded as one of the most promising CO 2 capture technologies.…”

Support-free cross-linked polyethyleneimine sorbent (CPEI) for CO2 capture was evaluated as the regenerable sorbent. The total amines available for the CO2 capture on CPEI were determined by the polyethyleneimine/glutaraldehyde ratio for the synthesis of CPEI. The CO2 capacity of CPEI in the slurry bubble column reactor reached 4.92 mmol/g, which is 1.97 times higher than that obtained under anhydrous conditions. The adsorption kinetics of CPEI in the reactor were investigated in terms of the CPEI amount, the CO2 fraction, the gas flow rate, temperature, and the total amines available. The experimental breakthrough curves for the sorbent were well-fitted with a fractional-order kinetic model. The modeling analysis found the influence of diffusion resistance on the adsorption is more significant than that of the driving force. The CO2 capacity of CPEI remained almost constant during the temperature swing adsorption/desorption cycles.
