“…It was reported that specific growth of Chlorella sorokiniana was 0. [16]. All of those reported values are in the same order with the result of this study for Chlorella pyrenoidosa with specific growth rate of 0.45 d -1 (when subjected to air with around 0.034 % CO 2 , light intensity of 8000 lux and photoperiod of 12 hour) and growth rate of 0.36 d -1 when subjected to 8000 lux but with photoperiod of 16 hours.…”

“…M CO 2 is the molar mass of carbon dioxide and MC is the molar mass of carbon. Typical carbon content of biomass ranges from 41 -51 % of weight of biomass [16]. In our analysis the approach is to use 50% average of carbon content of biomass in Equation (4) following the average carbon content (% weight) resulted from elemental analysis across several CO 2 concentration on C.pyrenoidosa [17].…”

Abstract. Microalgae have been viewed as one of potential solution for CO 2 biofixation or CO 2 sequestration. However, many factors need to be evaluated to support development of CO 2 biofixation. One important environmental factor for the growth of micro algae is related with light requirement. The aim of this study was to evaluate the effect of light intensity and photoperiod on growth of Chlorellapyrenoidosa (C.pyrenoidosa) and CO 2 biofixation. Experiments were carried out in 1000 mL semi batch photo bioreactors, purged continuously with air (0.034% CO 2 ). An Experiment of Factorial Design was employed in which the light intensity was evaluated 4 level at 2000, 4000, 6000 and 8000 lux with 3 level of photo period at L/D (light /dark) 8 hours/16 hours; L/D 12 hours/12 hours and L/D 16 hours/8 hours. The result indicated that both light intensity and photo period had significant effect (p< 0.05) on growth of C. pyrenoidosa. However, the photo period showed stronger effect relative to light intensity on growth of C.pyrenoidosa within the range reviewed. The interaction between the two factors was indicative but statistically not significant. Best growth profile sustained at combination of L/D 16 hours/8 hours of photoperiod and light intensity of 8000 lux with the highest average biomass observed at 0.516 ± 0.069gr/L. An increase in CO 2 biofixation rate of around 2 times was also observed between highest setting (8000 lux; L/D 16/12 hours) relative to that of lowest setting (2000 lux; L/D 8/12 hours).

“…The rate of biofixation of CO 2 by Chlorella sp. was tested and the results showed the values of 700 mg L -1 .d -1 (Adamczyk et al, 2016). The tolerance of CO 2 concentration can divide microalgae into two groups, as follows: sensitive to CO 2 (less than 2-5%) and tolerant to CO 2 (5-20%) (Miyachi et al, 2003).…”

Climate change, global warming, and rising prices for oil and petroleum products caused by the reduction of energy security are the main reasons why researchers are currently focused on renewable energy from microalgae (Mobin et al., 2014). Microalgae have the potential to be a substitute for traditional crops (rapeseed, corn silage) due to rapid growth and their high photosynthetic efficiency. Algae biomass can be cultivated in a number of different types of photobioreactors, water reservoirs or greenhouses. As examined by Tsai, Chen and Ramaraj (2017), microalgae were universally accepted as the ideal solution for monitoring of the greenhouse gas emissions. The research has shown the perfect uptake of CO 2 (the amount of 159 mgL -1.day -1 with 93% of CO 2 consumption efficiency) (Tsai, Chen and Ramaraj, 2017). Microalgae -production of biomassMicroalgae are the simplest autotrophic organisms (mostly microscopic) with undemanding requirements for growth and increasing growth rates depending on the environmental conditions created in the growth medium. The key factors to control the growth of algae are: water, light, CO 2 , temperature and optimum ratio of N : P : K. During the most important growth phase of algae growth -the exponential phase -there can be observed the doubling of biomass in less than 3.5 hours. The microscopic algae can be used to utilise the waste carbon dioxide (CO 2 ), 1 kg of dry biomass of algae will use approximately 1.83 kg of CO 2 (Brennan and Owende, 2009). Microalgae can be considered as a suitable substrate for anaerobic digestion due to high productivity and reduced need for the use of arable land.One of the most important factors for the overall success of microalgae cultivation is the selection of a suitable genus of algae (Bruton et al., 2009). The selection of optimal and proper types of algae results in a more effective conversion of biomass into methane. When selecting an appropriate genus of microalgae, it should be noticed that one of the most important parameters is the characteristic structure of the cell wall of microalgae, which determines the efficiency of the anaerobic process. Some species lack a cell wall, some microalgae have a wall consisting of a protein without cellulose or hemicellulose, and these parameters are the key ones to easier biodegradability. When selecting microalgae species for anaerobic digestion, it is necessary to take into account other parameters, for instance, productivity and sensitivity to contamination. If the selected species of microalgae have strong cell walls and are resistant to the anaerobic digestion process, algae biomass should be first processed before being used as a raw material in a biogas plant.Due to the high photosynthetic efficiency and intense growth in the context of cultivation of microalgae, there is an ongoing study of green microalgae as a promising feedstock for the production of fuels and chemicals. The cultivation of algae biomass for the production of biofuels is an interesting biomaterial for researchers worldwid...
