Thermodynamic assessment of algal biodiesel utilization
Sorguven, Esra; Özilgen, Mustafa - In: Renewable Energy 35 (2010) 9, pp. 1956-1966
In late 1990's some microalgae were found to be capable of producing lipids from carbon dioxide via photosynthesis with thirty times the efficiency of plants in terms of the amount of oil produced per unit area of the land allocated. This process raised hope in the fight against environmental...

Isolation of a new highly CO2 tolerant fresh water Microalga Chlorella sp. KR-1
Sung, K.D.; Lee, J.S.; Shin, C.S.; Park, S.C. - In: Renewable Energy 16 (1999) 1, pp. 1019-1022
A fresh-water microalga, which has tolerance to high concentrations of CO2, was isolated. The KR-1 strain was identified to be as genus Chlorella. Though Chlorella KR-1 showed maximum growth at 10% CO2, the strain showed a good growth rate up to 50% CO2. The results indicated the feasibility of...

Development of an effective acidogenically digested swine manure-based algal system for improved wastewater treatment and biofuel and feed production
Hu, Bing; Zhou, Wenguang; Min, Min; Du, Zhenyi; Chen, Paul - In: Applied Energy 107 (2013) C, pp. 255-263
An effective semi-continuous process was developed to grow a locally isolated green microalga Chlorella sp. on acidogenically digested swine wastewater in bench scale for improved algal biomass production and waste nutrient removal using central composite design (CCD). The influences of two key...

Chlorella sp.: A new strain with highly saturated fatty acids for biodiesel production in bubble-column photobioreactor
Rasoul-Amini, Sara; Montazeri-Najafabady, Nima; … - In: Applied Energy 88 (2011) 10, pp. 3354-3356
The biodiesel production from a naturally isolated strain of Chlorella in 2L bubble-column photobioreactor was studied. The microalgal strain was isolated from the rice paddy-field soil samples during a screening program. After 17days, at the end of exponential phase of growth, the total content...

Influence of influent methane concentration on biogas upgrading and biogas slurry purification under various LED (light-emitting diode) light wavelengths using Chlorella sp.
Yan, Cheng; Zhang, Li; Luo, Xingzhang; Zheng, Zheng - In: Energy 69 (2014) C, pp. 419-426
Raw biogas is a valuable renewable energy but usually requires upgrading. The mixed LED (light-emitting diode) light wavelengths achieved much better microalgae growth than that of the monochromatic. The best LED light wavelength mix ratio for both biogas upgrading and biogas slurry nutrient...
